'Chest gossypiboma after spinal surgery, not so easy to forget'.

During any surgical procedure, complications may arise, some of which are fortuitous, whereas others, unfortunately, occur because of errors of the surgical team. Fortunately, most are minor and do not affect the patient's recovery, but others can cause severe morbidity and even mortality. A retained cotton or gauze surgical sponge inadvertently left in the body during an operation is known as a gossypiboma. This dreadful oversight is a marked complication that can cause serious postoperative complications, a severe economic burden on the healthcare system, and many medicolegal implications. We report the case of a 30-year-old male, who suffered a spinal fracture which was repaired through an anterior fixation approach 12 years ago in a local state hospital without complications. Suddenly, he presented with chest pain and cough, and sought medical attention. An 8 × 5 × 8 cm low-density heterogeneous mass was discovered on his chest; after successful surgery, a gossypiboma formed by several gauzes without radiopaque markers was discovered.

Gossypiboma discovered 24 years after prostate surgery, a forgotten but never forgiven complication.

Forgetting gauze or "a surgical drape" inside a patient after surgery is a rare medical error. It can lead to severe complications, high hospital costs and medico-legal implications. As a result, this complication is often not reported, mainly to avoid retaliation and because it can initiate extensive critical press coverage. This technical oversight may be just the tip of an iceberg concerning the reality of surgical errors; therefore, the entire surgical team must focus on prevention, continuing medical education and strict adherence to protocols and counting guidelines to minimize their incidence. We present the case of a 76-year-old patient with an acute abdomen; after an initial evaluation, a gossypiboma was discovered, which was forgotten 24 years after prostatectomy.

Textiloma abdominal: actualización y aporte al diagnóstico desde las imágenes

Textiloma es un término utilizado para describir una masa formada por textiles quirúrgicos olvidados al interior de un paciente y la reacción a un cuerpo extraño que los rodea. Su incidencia ha disminuido considerablemente, sin embargo, su alto impacto legal y social ha motivado su revisión. Se realizó una búsqueda de artículos relacionados con textilomas vía Pubmed y SCielo, incluyendo un total de 25 referencias. La presentación clínica es variada e inespecífica; la ubicación, tiempo de evolución y tipo de respuesta inflamatoria inciden en un amplio espectro de escenarios clínicos, desde un hallazgo incidental en imágenes hasta un cuadro grave secundario a complicaciones (abscesos, obstrucción intestinal, sepsis, entre otros). En este contexto se hace fundamental el apoyo imagenológico. La radiografía simple suele ser el acercamiento inicial por su fácil acceso e interpretación, pero el marcador radiopaco puede desintegrarse o distorsionarse con el tiempo. La tomografía computada permite una mayor sensibilidad para el diagnóstico, pero puede ser fácilmente malinterpretada como una neoplasia, absceso o hematoma si no se conocen las características distintivas. La presencia de una masa de contenido espongiforme hipodenso con burbujas en su interior y una pared que realza con contraste o la de una masa reticular rodeada de una corteza calcificada deben orientar a su diagnóstico. Los textilomas son en definitiva problemas complejos, no sólo desde el ámbito legal y social sino también desde un punto de vista médico, siendo el estudio de imágenes y el antecedente de un procedimiento quirúrgico las claves para un diagnóstico oportuno.

Gossypiboma is a term used to describe a mass formed by textiles left inside a patient during surgery and the foreign body reaction that surrounds it. Its incidence has considerably decreased over time; however, its legal and social impact has motivated its revision. Articles were searched via PubMed and SCielo and a total of 25 references were included from it. Gossypibomas have a wide and nonspecific clinical presentation; location, time of evolution, and type of inflammatory response determine the wide spectrum of clinical scenarios that can go from an incidental diagnosis in images to severe clinical condition secondary to complications (abscess, bowel obstruction, sepsis, within others). In this context, imaging support becomes essential. Plain radiography is usually used as the initial approach due to its easy access and interpretation; however, the radiopaque marker can distort or disintegrate over time. The computed abdomen tomography allows an increased sensitivity for the diagnosis but findings can easily be misinterpreted as a neoplastic disease, abscess or hematoma if the distinctive characteristics are not known. The finding of a hypodense spongiform mass with air bubbles inside and contrast enhanced wall or a reticular mass surrounded by a calcified cortex should guide us to its diagnosis. Gossypiboma is definitely a complex issue, not only from a legal and social scope but also from a medical point of view, being the study by images and the history of surgical procedures the keys for a timely diagnosis.

Arritmia ventricular maligna asociada a un gossypiboma: reporte de un caso / Malignant ventricular arrhythmia associated to gossypiboma: clinical case report / Arritmia ventricular maligna vinculada a gossypiboma: reporte de um caso clínico

Un gossypiboma, oblitoma o textiloma se define como todo cuerpo extraño olvidado en el interior de un paciente durante una intervención quirúrgica. Representa una complicación posquirúrgica poco frecuente pero de consecuencias potencialmente graves. En general, se manifiesta con cuadros clínicos variables: una masa o pseudotumor, sangrados, fiebre, dolor, varios meses o años después de la cirugía original. También puede ser un hallazgo accidental. Describimos el caso clínico de una paciente con un gossypiboma vinculado a una cirugía cardíaca que se realizó 40 años antes al cuadro clínico actual, que se presenta con arritmia ventricular maligna.

A gossypiboma, oblitoma or textiloma is defined as a surgical object left in the interior of the body after surgery. It represents an uncommon but potentially life threatening post-surgery complication. Clinical manifestations are variable and depend on location, relations and size, from pseudo-tumoral masses, bleeding, fever, pain and other nonspecific presentations. The onset of symptoms is unpredictable, occurring from months or years after surgery. Patients may course asymptomatically and be diagnosed incidentally as an imaging finding. We describe a case of a patient with gossypiboma diagnosed 40 years after undergoing cardiac surgery, who presented with a malignant ventricular arrhythmia.

Um gossypiboma, oblitoma ou textiloma está definido como todo corpo estranho esquecido no interior de um paciente durante um procedimento cirúrgico, representando uma complicação pos cirúrgica pouco frequente, mas com consequências potencialmente graves. Geralmente, se manifesta com quadros clínicos variáveis: uma massa ou pseudotumor, sangramentos, febre, dor, varios meses ou anos após a cirurgia original ou ser um hachado acidental. Descrevemos o caso clínico de uma paciente com um gossypiboma vinculado a uma cirurgia cardíaca realizada 40 anos antes do quadro clínico atual, que se apresenta com arritmia ventricular maligna.

Gossypiboma vesical: reporte de 2 casos y revisión de la literatura / Bladder gossypiboma: report of 2 cases and review of the literature

La presencia de gasas intracavitarias posterior a procedimientos quirúrgicos es una situación que genera importantes complicaciones, con graves repercusiones médico-legales. El objetivo de este estudio es describir la presencia de un cuerpo extraño vesical como complicación iatrogénica. Se presentan dos casos, el primero es de un hombre de 63 años de edad, con antecedente de prostatectomía simple por hiperplasia prostática benigna, quien acude por episodio de retención aguda de orina (RAO); y el segundo es de una mujer de 65 años, con antecedente de histerectomía abdominal por leiomiomatosis uterina, quien presenta dolor pélvico crónico e infecciones urinarias a repetición. A los pacientes se les realizó un ecosonograma pélvico que reportó lesión ocupante de espacio en vejiga, la urotomografia (urotac) evidencia un cuerpo extraño intravesical de apariencia radiopaca, y en la uretrocistoscopia se visualiza material sintético intravesical flotando. Al primer paciente se le realiza una cistotomía con extracción de material compatible con gasa y a la segunda paciente se le realiza extracción endoscópica de la misma, ambos presentando evolución satisfactoria. La revisión del sitio quirúrgico y el contaje transoperatorio de gasas antes de la síntesis final de los tejidos es un paso fundamental para el éxito de una cirugía pélvica(AU)

The presence of intracavitary gauzes after the surgical procedures is a situation that generates important complications, with serious medico-legal repercussions. The objective of this study is describe the presence of a bladder foreign body as an iatrogenic complication. Two cases are presented, the first is from a 63-year-old man with a history of simple prostatectomy for benign prostatic hyperplasia who presents with episodes of acute urinary retention; and the second is a 65-year-old woman with a history of abdominal hysterectomy due to leiomyomatosis that presents with chronic pelvic pain and recurrent urinary tract infections. A pelvic ecosonogram was performed on the patients who reported a bladder space-occupying lesion, urotac showed an intravesical foreign body with a radiopaque appearance, and intravesical synthetic flotation material was visualized in the urethrocystoscopy. The patient underwent a cystotomy with gas-compatible material extraction and the patient underwent endoscopic extraction, both showing a satisfactory evolution. Surgical site revision and transoperative gauze infection before the final synthesis of tissues is a fundamental step for the success of pelvic surgery(AU)

Intraconal gauze mass: An unusual complication of orbital fracture repair - a case report.

Gossypiboma and textiloma are terms used to describe tumor-like masses caused by retained gauze or surgical sponges after any operation. It is a rare surgical complication, usually difficult to diagnose due to its variable clinical presentation and nonstandard radiological appearance. We describe here a rare case of orbital gossypiboma in a child after surgical correction of an orbital blowout fracture.

Oblitos en Cirugía: análisis de casuística y estrategias para su prevención / Foreign body: case analysis and prevention strategies / Oblitos em Cirurgia: análise de caso e estratégias de prevenção

Introducción: El oblito es un evento de muy baja frecuencia pero que puede generar morbilidad grave. Si bien se han reconocido algunos factores de riesgo y desarrollado sistemas complementarios de detección, continua siendo un gran problema desde el punto de vista sanitario y médico legal. Objetivos: Analizar una casuística del Hospital Maciel, su forma de presentación y complicaciones. Pacientes y métodos: Se presentan 7 pacientes asistidos en los Servicios de Cirugía General y Urología del Hospital Maciel, en el período comprendido del 2013 - 2016. Las principales variables que se analizan son la forma de presentación y complicaciones, así como presencia de factores de riesgo. Resultados: El hallazgo fue de compresas en todos los pacientes. En 2 casos el oblito fue asintomático y en otros 4 sintomático. En los últimos, 2 tuvieron una presentación temprana y 2 tardía. El recuento de material fue incorrecto solamente en un caso. Ningún paciente falleció por las complicaciones resultantes. Discusión: El oblito en cirugía es un problema que seguirá existiendo en tanto existan los procedimientos quirúrgicos, por lo que es necesario hacer énfasis en el abordaje sistemático, existiendo también métodos auxiliares de diagnóstico que podrían comenzar a implementarse. Conclusiones: Encontramos casi sin excepción la presencia de factores de riesgo conocidos en nuestra serie, si bien el número de casos es reducido. También la incidencia impresiona ser algo más elevada de la señalada en la literatura.

Introduction: Retained foreign items are infrequent but can generate serious morbidity. Although some risk factors have been recognized and complementary detection systems developed, it continues to be a major problem from a health and medical legal point of view. Objectives: to examine a case study at Hospital Maciel, focusing on clinical presentation and complications. Patients and methods: 7 patients treated at the General Surgery and Urology Departments in Hospital Maciel, between 2013-2016. The main results analized are clinical presentation and complications, as well as the presence of recongnized risk factors. Results: In all patients, the foreign bodies were compresses. In 2 cases the foreign body did not elicit symptoms whereas in 4 cases it did. In the latter, 2 had an early and a late presentation. The material count was incorrect in only one case. No patient died from the resulting complications Discussion: Because retained surgical ítems will be a problem as long as surgical procedures are performed, it is necessary to emphasize on a systematic approach accompanied by complementary diagnostic tools that are also available in cases of item miscount. Conclusions: Risk factors were present almost without exception in our casuistry. Also, the incidence seems to be higher than that reported in the literature.

Introdução: Oblito é um evento de baixa freqüência, mas que pode gerar uma grave morbidade. Embora alguns fatores de risco tenham sido reconhecidos e desenvolvidos sistemas de detecção complementares, continua a ser um grande problema do ponto de vista da saúde e do direito médico legal. Objetivos: Analisar uma casuística do Hospital Maciel, sua apresentação e complicações. Pacientes e métodos: sete pacientes foram atendidos nos Serviços de Cirurgia Geral e Urologia do Hospital Maciel, no período entre 2013 e 2016. As principais variáveis analisadas são a apresentação e complicações, bem como a presença de fatores risco. Resultados: a descoberta foi de compressas em todos os pacientes. Em 2 casos, o oblito foi assintomático e em 4 casos foi sintomático. No segundo, em 2 a apresentação foi temprana e em 2 foi tardia. A contagem de materiais estava incorreta em apenas um caso. Nenhum paciente morreu pelas complicações resultantes. Discussão: o oblito em cirurgia é um problema que continuará a existir enquanto houver procedimentos cirúrgicos, por isso é necessário enfatizar a abordagem sistemática, e também há métodos de diagnóstico que podem ser implementados. Conclusões: encontramos quase sem exceção a presença de fatores de risco conhecidos em nossa série, embora o número de casos seja pequeno. A incidência também parece ser um pouco maior do que a relatada na literatura.

What type of imaging work-up will help to confirm the diagnosis of gossypiboma in the limb? Review of literature.

UNLABELLED: Gossypiboma imaging features are not well known and are often confused with soft tissue tumours. Publications on this topic mainly consist of case reports and small cohorts. Its appearance on various imaging modalities is not well defined. This led us to carry out a review of literature to determine specifically: (1) which imaging modalities should be used in cases of suspected gossypiboma, (2) what are the most common imaging findings that contribute to the diagnosis of gossypiboma. An exhaustive review of literature was carried out in June 2015 in the Medline, PubMed and Cochrane databases using the keywords "gossypiboma/textiloma/foreign body". We found 205 articles describing one or multiple cases of gossypiboma in various locations. Of these, the 32 articles that had imaging data were chosen - 16 for the limbs and 16 for other locations. The type of imaging carried out, description of the gossypiboma and circumstances of the discovery and occurrence were recorded. Descriptive statistics were generated to define the type of imaging used and the various findings. Imaging consisted of X-rays in 21/32 cases (66%), computed tomography (CT) in 14/32 cases (43%), magnetic resonance imaging (MRI) in 21/32 cases (65%) and ultrasonography in 14/32 cases (43%). On X-rays, bone involvement was found in 9/15 cases (60%); there was peripheral contrast product uptake on the CT scans in 9/14 cases (64%), a hypointense signal on T1-weighted sequences on MRI in 6/13 cases (46%) and lack of vascularisation in 8/13 cases (62%) and a acoustic shadow on ultrasonography in 9/14 cases (64%). In a patient presenting with a soft tissue lump and history of surgery, an imaging work-up including X-rays, ultrasonography and MRI must be performed. Bone involvement on X-rays, acoustic shadowing on ultrasonography and hypointense signal on T1-weighted MRI sequences with lack of vascularisation in combination with a history of surgery can bring up the possibility of gossypiboma. If there is a possibility of soft tissue tumour, the case should be discussed in a multidisciplinary meeting and a biopsy should be performed first. LEVEL OF EVIDENCE: IV - systematic analysis of published retrospective studies.

[Intestinal occlusion secondary to a retained surgical item]. / Oclusión intestinal secundaria a oblito quirúrgico.

BACKGROUND: Retained surgical items after a surgical procedure is a real, existing, and preventable problem that affects the safety of the surgical patient. Its incidence is not exactly known due to under-reporting of occurrence, due to the potential risk of lawsuits. CLINICAL CASE: A 31 year-old women that had an elective caesarean, apparently without complications. In the immediate post-operative period, clinical features appeared that were compatible with intestinal obstruction, such as inability to channel gas, bloating, abdominal pain and vigorous peristalsis. The diagnosis is made by the recent history of abdominal-pelvic surgery and the finding of a foreign body on a simple x-ray of the abdomen. The patient was operated upon, with a satisfactory outcome, and was discharged 5 days later. CONCLUSION: A retained surgical instrument is an under-reported event that represents a medical-legal problem, leading to various complications, including death if it is not diagnosed and treated early. It is important to know the risk factors and adopt a culture of prevention through perioperative monitoring of equipment and instruments used during the surgical act.

Duodenal gossypiboma: a case report and literature review / Gossypiboma duodenal: reporte de un caso y revisión de la literatura

Gossypiboma is a retained surgical cotton matrix material in the body after a surgical procedure. Cases are rarely reported due to medico-legal concerns. Although infrequent, it causes serious morbidity and even mortality if left undiagnosed. We present the case of a trans-mural migration of gossypiboma and a review of the literature. Gossypiboma’s trans-duodenal migration is a rare complication of retained gauzes. Cases reported in the literature were easy to diagnose based on clinical grounds and endoscopic studies.

La palabra gossypiboma define una gasa o matriz de algodón retenida en el organismo después de un procedimiento quirúrgico. Se reportan con poca frecuencia debido a las implicaciones médico-legales. A pesar de ser poco frecuentes, pueden ser causa de morbilidad si no se diagnostican. En el presente trabajo se reporta un caso de un gossypiboma con migración transduodenal. La migración transduodenal de un gossypiboma es una complicación rara que suele diagnosticarse sin dificultad con base a la clínica y a la endoscopía.

Gossipiboma após operação abdominal é situação clínica desafiadora e sério problema médico legal / Gossypiboma after abdominal surgery is a challenging clinical problem and a serious medicolegal issue

INTRODUÇÃO: O termo gossipiboma refere-se à matriz que contém material têxtil e à reação tecidual formada ao redor deste corpo estranho. As gazes e as compressas cirúrgicas são os materiais mais frequentemente retidos após laparotomias. OBJETIVO: Estudar a incidência e as causas de gossipiboma abdominal, além das medidas preventivas para reduzir a sua frequência e morbimortalidade. MÉTODO: Foi realizada revisão da literatura na língua inglesa no Medline / Pubmed. A pesquisa envolveu os últimos 10 anos, selecionando os seguintes descritores - gossipiboma, textiloma, corpo estranho retido e cirurgia abdominal.Trinta artigos foram considerados para a revisão. RESULTADOS: A incidência é subestimada, principalmente pelas implicações legais decorrentes de tal achado, mas também porque muitos pacientes permanecem assintomáticos. Ocorrem em 1/1000 a 1/1500 operações abdominais. A apresentação clínica é variável e depende da localização do corpo estranho e do tipo de reação inflamatória apresentado pelo hospedeiro. A migração transmural é rara. O tratamento recomendado é a excisão, realizado por via endoscópica, laparoscópica ou por laparotomia, com o objetivo de evitar as complicações que podem atingir alta mortalidade. A abordagem mais importante é a prevenção. As medidas preventivas incluem o uso de material têxtil com marcadores radiopacos, exploração detalhada da cavidade abdominal ao final do procedimento operatório e contagem meticulosa do material cirúrgico. CONCLUSÃO: Gossipiboma é problema médico-legal antigo, cuja incidência aparentemente está aumentando e que precisa ser reabordado para que medidas preventivas efetivas sejam adotadas na sala de operação.

INTRODUCTION: The term "gossypiboma" refers to a textile matrix surrounded by foreign body reaction. Gauze and surgical dressings are the most commonly retained materials after laparotomy. AIM: To evaluate the incidence of abdominal gossypiboma, its causes and the preventive measures to reduce the frequence and morbimortality. METHOD: Was conducted a literature review in Medline/Pubmed in english. The survey was about the last 10 years, selecting the headings: gossypiboma, textiloma, retained foreign body and abdominal surgery. Thirty articles were considered in this review. RESULTS: The incidence of gossypiboma is underreported, mostly due to the legal implications of their detection but also because many patients remain asymptomatic. Occur in 1/1000 to 1/1500 of intra-abdominal operations. Clinical presentation is variable, and depends on the location of the foreign body and on the type of inflammatory reaction presented by the host. The recommended course of treatment is excision, which can be accomplished endoscopically, laparoscopically, or via the open route, and seeks to prevent the complications that lead to a high mortality rate. The most important approach is prevention. Preventive measures required include exploration of the abdominal cavity at the end of the procedure, use of textiles with radiopaque markers and a meticulous account of surgical materials. CONCLUSION: Gossypiboma is a former medical-legal problem, whose incidence is apparently increasing. Therefore needs to be revised to take preventive measures in the operating room.

Retained surgical sponge mimicking GIST: Laparoscopic diagnosis and removal 34 years after original surgery.

The term gossypiboma denotes a cotton foreign body retained inside the patient during surgery, a rare surgical complication. The symptoms following this entity are non-specific, such as pain, palpable mass and fever, which make clinical diagnosis difficult. The computerized tomography (CT) scan is the most useful method for diagnosis; however, sometimes the preoperative diagnosis remains uncertain even after the imaging exam. In that case, laparoscopy arises as a valuable diagnostic tool, as well as a prompt treatment option. However, when diagnosis is made years after the original surgery, the laparoscopic approach becomes harder. Our patient presented without clear symptoms, remaining asymptomatic for 34 years. The CT scan presumptive diagnosis was a gastrointestinal stromal tumour, and laparoscopy was performed providing an accurate diagnosis and treatment in the same surgical time.

[Postoperative intra-abdominal foreign body resemblance to neoplasm. Report of a case and review of the bibliography]. / Cuerpo extraño intra-abdominal postquirúrgico simulador de neoplasia. Presentación de un caso y revisión de la bibliografía.

INTRODUCTION: Gossypibomas or textilomas are materials remain in the abdomen after surgery. It is very difficult to assess its impact due to medico-legal implications, hence the interest in the publication of this type of pathology. CLINICAL CASE: Women of 76 years who had undergone a hysterectomy and double anexectomy 6 months before admission to our hospital, apparently without perioperative complications. When she was assessed in our hospital she had a clinical picture simulating a malignancy. In our case, the patient had signs and symptoms of advanced intra-abdominal malignancy, such as chronic anemia, significant weight loss and palpable abdominal mass. The diagnostic procedure combined computed tomography and colonoscopy, aiming to find the signs of intra-abdominal gossypiboma. Three bowel resections were performed to extract the foreign body, with satisfactory postoperative results and remaining asymptomatic to date. CONCLUSION: Intra-abdominal gossypibomas are exceptional, although the diagnosis is made through imaging and, if suspected GI neoplasm, endoscopic studies. The primary differential diagnosis must be made with intra-abdominal malignancies.

Gossypiboma: el sempiterno problema de los cuerpos extraños retenidos y el privilegio del internista / Gossypiboma: the always present problem of surgical strange object`s retention and the internis` privilege

La retención de objetos quirúrigicos o cuerpos extraños durante un acirugía, es un problema ampliamente reconocido en el sistema de atención de la salud. Causa daño a los pacientes, proveedores, hospitales, comunidades y al sistema de atención dela salud como todo. También resulta en gastos inncesarios. La retención de objetos quirúrgicos es un problema totalmente evitable. Se presenta el caso de una mujer diabética que presentó una parálisis incompleta tercer nervio central y durante la explotación física integral, privilegio del internista, se encontró un tumor abdominal asintomátco. La tomografía computarizada fue compatible con una retención de objetos quirurgicos. Este artículo exmina los factores de riesgo para que ocurra la retención, examina los métodos actuales de prevención y los estudios de las nuevas tecnologías que se han desarrollado para evitar este error médico

The retention of surgical objects is a widely recognized problem within the health care system. It causes harm to patients, providers, hospitals, communities, and to the health care system as a whole. It also results in needless expense. The retention of surgical objects is a problem completely preventable. We presented the case of a diabetic woman who presented with incomplete third nerve palsy and incidentally, as an internist`s privilege, an asymptomatic abdominal tumor was clinicaly found. The computarized tomography scan was compatible with a retention of surgical objects. This article reviews the risk factors for retention of surgical objects, examines the current methods of prevention, and surveys the new technologies that have been developed to prevent this medical error

Avaliação por imagem dos gossipibomas abdominais / Imaging findings of abdominal gossypibomas

O termo gossipiboma é usado para descrever uma massa formada a partir de uma matriz de algodão cercada por uma reação inflamatória/granulomatosa. Sua incidência é estimada em 0,15 por cento a 0,2 por cento. O corpo estranho na cavidade abdominal pode servir de nicho para a proliferação de microrganismos e agir como foco primário para formação de abscessos e de peritonite. Vários estudos têm demonstrado a importância da correlação clínica com os diversos métodos de imagem (radiografia convencional, ultrassonografia, tomografia computadorizada e ressonância magnética) no diagnóstico dos gossipibomas. Este ensaio tem por objetivo demonstrar uma série de casos típicos de gossipibomas abdominais e ilustrar suas diversas formas de apresentação, com ênfase nos achados dos diferentes métodos de imagem, visando a familiarizar os radiologistas com esta enfermidade e seus principais diagnósticos diferenciais.

Gossypiboma is a term utilized to describe a mass developed from a matrix of cotton fibers surrounded by inflammatory granulomatous reaction. Its incidence is estimated at 0.15 percent to 0.2 percent of laparotomies. A foreign body within the abdominal cavity may provide a niche for proliferation of microorganisms, acting as primary focus for development of an abscess and peritonitis. Several studies have demonstrated the relevance of clinical correlation with the findings of different imaging methods (conventional radiography, ultrasonography, computed tomography and magnetic resonance imaging) in the diagnosis of gossypibomas. The present pictorial essay is aimed at demonstrating a series of typical cases of abdominal gossypibomas and illustrating the several presentations of such mass, with emphasis on the findings at different imaging methods in order to familiarize radiologists with this entity and with the main differential diagnosis.

Características de imagem na ressonância magnética de gossipiboma intracraniano: relato de caso e revisão da literatura / Magnetic resonance imaging findings of intracranial gossypiboma: a case report and literature review

Vários trabalhos têm descrito as características de gossipibomas por meio de radiografias convencionais e tomografia computadorizada, porém, seus achados na ressonância magnética são menos conhecidos. O objetivo deste estudo foi descrever as características de imagem de gossipibomas, ilustrando um caso de uma paciente com quadro clínico de febre e confusão mental com antecedente de cirurgia encefálica.

Many reports in the literature have described findings of gossypibomas at conventional radiography and computed tomography. However, magnetic resonance imaging findings are still to be completely known. The purpose of the present study was to describe imaging findings of gossypibomas in a patient with previous history of brain surgery, presenting fever and mental confusion.

Corpo estranho intratorácico: achados radiológicos / Intrathoracic gossypiboma: imaging findings

Os autores relatam três casos de corpo estranho intratorácico, que é definido como uma massa de matriz de algodão, e geralmente se refere a compressa cirúrgica retida, uma rara complicação das cirurgias torácicas. Os pacientes foram examinados por radiografia de tórax e tomografia computadorizada,sendo os achados de imagem confirmados por toracotomia e estudo anatomopatológico. Os principais achados de imagem são de massas intratorácicas em pacientes com história de cirurgia prévia apresentando sintomas relacionados ao trato respiratório inferior em tempo variávelapós a intervenção cirúrgica. Foram analisados os principais achados de imagem dos três casos de corpo estranho intratorácico e correlacionados com revisão da literatura.

The authors report three cases of intrathoracic foreign body that is defined as a cotton matrix mass, mostly retained surgical sponge, a rare complication of a thoracic surgery. The patients wereevaluated by chest radiography and computed tomography with the imaging findings confirmed after thoracotomy and anatomopathological study. The mainly imaging findings consisted of intrathoracic masses in patients with previous thoracic surgery that return to hospital with lower respiratory tract symptoms in different period after surgery procedure. The three cases were related with a brief review of the literature.
