ABSTRACT

Se presenta el caso de un paciente masculino VIH positivo con historia de cefalea y rigidez nucal. Dada su condición clínica el paciente es hospitalizado en sala. La radiografía de tórax es normal y se realiza tomografía de tórax de alta resolución debido a la historia clínica de VIH encontrándose un nódulo pulmonar solitario en el pulmón derecho con márgenes irregulares al cual se realiza biopsia dirigida por tomografía resultando un diagnóstico de micosis pulmonar.


A case of a positive VHI male patient with a history of headache and nuchal stiffness is reported. Gi­ven his clinical condition, the patient is hospitalized in the emergency room. The chest x­ray is nor­mal and a high­resolution chest tomography is performed due to the clinical history of HIV, finding a solitary pulmonary nodule in the right lung with irregular margins to which a biopsy directed by tomo­graphy is performed, resulting in a diagnosis of pulmonary mycosis.

ABSTRACT

Pulmonary placental transmogrification (PT) is a rare entity with less than 40 cases reported in the literature. Most reported cases are associated with either bullous emphysema or with pulmonary fibrochondromatous hamartomas. We present only the second case of PT associated with adenocarcinoma of the lung. A 67-year-old female with multiple chronic medical ailments presented with shortness of breath and was found to have a 6-cm mass in the upper lobe of her right lung. A computed tomography (CT) guided core biopsy was performed that showed a well-differentiated adenocarcinoma. Interestingly the normal lung tissue showed placental villous architecture. A unique feature of our case is that the diagnosis was made on a needle core biopsy, unlike all the other cases in the literature. We also provide a comprehensive review of this rare entity.

ABSTRACT

La definición clásica de nódulo pulmonar solitario corresponde a una imagen radiológica de menos de 3cms que puede corresponder a múltiples condiciones tanto benignas como malignas. Sin embargo con la masificación del uso del TAC de tórax se detectan actualmente diferentes tipos de NP pequeños, incluso subcentrimétricos: sólidos, en vidrio esmerilado (VE) y mixtos. Cada uno con diferente ritmo de crecimiento y diferente potencial de malignidad. Los recientes avances en oncología torácica, tanto en procedimientos diagnósticos como terapéuticos, han hecho que la definición clásica sea insuficiente para incorporar todas las variaciones en el comportamiento de los diferentes nódulos pulmonares que se pesquisan actualmente. Aparte del enfrentamiento habitual de nódulos sólidos de mayor tamaño, se ha definido el manejo de nódulos pequeños sólidos y subsólidos. Se ha establecido claramente que las lesiones en VE tienen un mayor riesgo de malignidad, existiendo una buena correlación entre el aspecto radiológico y el grado histológico. Las lesiones mixtas que persisten en el tiempo y las lesiones en VE en que se desarrolla un componente sólido son las de más alto riesgo de representar un Adenocarcinoma invasor. Por tanto, todos los nódulos, incluso más pequeños subcentrimétricos, deben ser evaluados por equipos multidisciplinarios, con experiencia en los diferentes algoritmos de manejo y seguimiento. Determinando qué nódulos biopsiar de manera de poder resecar tumores iniciales potencialmente curables. Los tumores pequeños pueden ser operados con técnicas quirúrgicas mínimamente invasivas, incluso resecciones sublobares, con similares resultados oncológicos, pero con menor riesgo y menor deterioro de la capacidad funcional.


The definition of a solitary pulmonary nodule corresponds to a radiological image of less than 3cms that may correspond to multiple conditions both benign and malignant. However with the extended use of Chest CT a great number of small sub-centrimetric Pulmonary Nodules are detected: solids, ground-glass opacities (GGO) and mixed lesions. Each with different growth rates and malignant potential. Diagnostic and treatment advances in thoracic oncology, made the classic definition insufficient to incorporate all the difference in growth rate and behavior of the different lung nodules currently detected. In addition to the management larger solid nodules, new diagnostic and treatment algorithms for small GGO and mixed nodules have been defined. It has clearly established that GGO lesions have an increases risk of malignancy, with correlation between radiologic imaging and pathology. Mixed lesions that persist or enlarge during follow-up, or GGO lesions that develop a solid component have the higher risk of representing an invasive adenocarcinoma. Therefore, all nodules, even small sub-centrimetric, should be evaluated by multidisciplinary teams, with experience in management and treatment algorithms determining when to resect potentially curable tumors. Small tumors can be resected by minimally invasive surgery, including sub lobar resections, with equivalent oncologic outcomes, lower risks and better preservation of pulmonary function.

ABSTRACT

OBJECTIVE: To investigate the clinical application of CT and CT-guided percutaneous transthoracic needle biopsy (CT-PTNB) in patients with indeterminate pulmonary nodules (IPNs). METHODS: We retrospectively studied 113 patients with PNs undergoing CT and CT-PTNB. Variables such as gender, age at diagnosis, smoking status, CT findings, and CT-PTNB techniques were analyzed. Data analysis was performed with the Student's t-test for independent samples the chi-square test, and normal approximation test for comparison of two proportions. RESULTS: Of the 113 patients studied, 68 (60.2%) were male and 78 (69%) were smokers. The diameter of malignant lesions ranged from 2.6 cm to 10.0 cm. Most of the IPNs (85%) were located in the peripheral region. The biopsied IPNs were found to be malignant in 88 patients (77.8%) and benign in 25 (22.2%). Adenocarcinoma was the most common malignant tumor, affecting older patients. The IPN diameter was significantly greater in patients with malignant PNs than in those with benign IPNs (p < 0.001). Having regular contour correlated significantly with an IPN being benign (p = 0.022), whereas spiculated IPNs and bosselated IPNs were more often malignant (in 50.7% and 28.7%, respectively). Homogeneous attenuation and necrosis were more common in patients with malignant lesions (51.9% and 26.9%, respectively) CONCLUSIONS: In our sample, CT and CT-PTNB were useful in distinguishing between malignant and benign IPNs. Advanced age and smoking were significantly associated with malignancy. Certain CT findings related to IPNs (larger diameter, spiculated borders, homogeneous attenuation, and necrosis) were associated with malignancy. .


OBJETIVO: Investigar a aplicação clínica da TC e da biópsia transtorácica percutânea guiada por TC (BTP-TC) em pacientes com nódulos pulmonares indeterminados (NPIs). MÉTODOS: Foram estudados retrospectivamente 113 pacientes portadores de NPIs submetidos a TC e BTP-TC. Foram analisadas variáveis como sexo, idade ao diagnóstico, tabagismo, achados tomográficos e técnicas de BTP-TC. A análise dos dados foi efetuada por meio do teste t de Student para amostras independentes, teste do qui-quadrado e teste de comparação de duas proporções por aproximação normal. RESULTADOS: Dos 113 pacientes estudados, 68 (60,2%) eram do sexo masculino e 78 (69%) eram tabagistas. O diâmetro das lesões malignas variou de 2,6 a 10,0 cm. A maioria dos NPIs estava localizada na região periférica (85%). O resultado da biópsia foi maligno em 88 pacientes (77,8%) e benigno em 25 (22,2%). O adenocarcinoma foi o tumor maligno mais frequente, acometendo pacientes com idade mais avançada. O diâmetro dos NPIs foi significativamente maior nos pacientes com malignidade (p < 0,001). Houve uma associação significativa entre NPIs com contorno regular e lesões benignas (p = 0,022), enquanto os de tipo espiculado e bocelado foram mais frequentes em pacientes com lesões malignas (50,7% e 28,7%, respectivamente). Atenuação homogênea e necrose foram mais frequentes em pacientes com lesões malignas (51,9% e 26,9%, respectivamente). CONCLUSÕES: A TC e a BTP-TC foram úteis no diagnóstico diferencial entre lesões malignas e benignas nos pacientes com NPIs nesta amostra. Idade mais avançada e tabagismo associaram-se significativamente com malignidade. Houve associações de achados tomográficos (diâmetro maior, contorno espiculado, atenuação homogênea ...

ABSTRACT

A síndrome de Swyer James-Mc Load é uma entidade rara descrita pela primeira vez em 1953 sendo caracterizada por hipoplasia ou agenesia das artérias pulmonares, resultando em hiperlucência pulmonar unilateral. Embora a patogênese ainda não tenha sido completamente elucidada, acredita-se que seja uma complicação pós-infecciosa de bronquiolites ocorridas na infância. O objetivo deste estudo estudo foi analisar a melhor conduta terapêutica na síndrome de Swyer James-Mc Load e o impacto na qualidade de vida das pessoas acometidas. Relata-se dois casos desta síndrome diagnosticados em pacientes adultos, sendo que uma delas apresenta asma persistente grave e a outra é ex-tabagista e já realizou cirurgia para ressecção de um nódulo pulmonar no pulmão contralateral ao acometido. A terapêutica conservadora foi capaz de estabilizar a condição clínica dos pacientes, mantendo uma boa qualidade de vida. No entanto, pacientes que não se estabilizam com tal terapêutica provavelmente devem ser incluídos à intervenção invasiva, visto que fornece ao paciente melhora na qualidade e expectativa de vida. Uma breve revisão da literatura pertinente foi realizada para melhor compreensão do assunto...


The Swyer-James Mc Load syndrome is a rare entity first described in 1953 and is characterized by hypoplasia or agenesis of the pulmonary arteries, resulting in unilateral lung hyperlucency. Although the pathogenesis has not yet been fully elucidated, it is believed to be a post-infectious complication of bronchiolitis occurring in childhood. The objective of this article was analyzing the best treatment for SSJM and its impact on affected people's lives. We report two cases of this syndrome diagnosed in adult patients, one of whom has severe persistent asthma and the other is a former smoker and has undergone surgery for resection of a pulmonary nodule in the contralateral lung to the affected. We concluded that conservative therapy is able to stabilize the clinical condition of patients maintaining a good quality of life. However, patients who do not stabilize with such therapy are likely to be included in invasive intervention, since it improves the quality of life and life expectancy of the patient. A brief review of the literature was conducted to better understand the subject...

ABSTRACT

La cirugía mínima invasiva constituye uno de los grandes avances de la medicina en las tres últimas décadas. La cirugía pediátrica no ha escapado a este progreso, y hoy en día son muchas las indicaciones de esta técnica en el niño. El nódulo pulmonar solitario se define como una lesión esférica rodeada por parénquima sano, no asociada a atelectasia y sin adenopatías mediastinales, Se reporta el caso deescolar femenino de 9 años de edad quien presentó evidencia radiológica de nódulo pulmonar solitario ubicado a nivel de la base del campo pulmonar derecho. Se realizó resección toracoscópica del mismo. Fueron descartadas patologías oncológicas, tuberculosis, micosis y enfermedades de depósito. Únicamente fue positiva la serología para Chlamydia pneumoniae (IgM), sin embargo, la pacientenunca presento clínica de infección respiratoria baja antes de su ingreso. La biopsia evidenció una lesión inflamatoria encapsulada inespecífica. Se concluye que la toracoscópia debe ser el método de primera elección ante cualquier lesión torácica y a cualquier edad enpediatría


Minimally invasive surgery constitutes one of the greatest advances of medicine in the last three decades. Pediatric surgery has not escaped this progress; in fact, nowadays there are many indications to perform this technique on children. Solitary pulmonary nodule is defined as a spherical lesion surrounded by healthy parenchyma, not associated with atelectasia and without mediastinallymphadenopathy. We present a nine-year-old girl, with radiological evidence of a solitary pulmonary nodule located at base of the right lung field. A thoracoscopic resection was performed. Oncological pathologies, tuberculosis, mycosis and deposit illnesses werediscarded. The only positive serology was for Chlamydia pneumoniae (IgM); however, the patient never presented clinical lower respiratory infection before her admission. The biopsy determined an encapsulated nonspecific inflammatory lesion. We conclude thatthoracoscopy should be the method of choice for any thoracic injury in children

ABSTRACT

OBJETIVO: Analisar características clínicas e radiográficas que influenciaram o diagnóstico anatomopatológico de nódulo pulmonar solitário (NPS) e comparar/validar dois modelos probabilísticos de malignidade do NPS em pacientes com NPS no Brasil. MÉTODOS: Análise retrospectiva de 110 pacientes com diagnóstico de NPS submetidos à ressecção em um hospital terciário no período entre 2000 e 2009. As características clínicas estudadas foram gênero, idade, presença de comorbidades sistêmicas, história de neoplasia maligna ao diagnóstico de NPS, diagnóstico histopatológico do NPS, tabagismo, carga tabágica e tempo de cessação do tabagismo. As características radiográficas avaliadas em relação ao NPS foram presença de margens espiculadas, tamanho do maior diâmetro transversal e localização anatômica do NPS. Foram utilizados dois modelos matemáticos, criados em 1997 e 2007, respectivamente, para determinar a probabilidade de malignidade do NPS. RESULTADOS: Houve associações significantes entre malignidade do NPS e idade (p = 0,006; OR = 5,70 para idade >70 anos), presença de margens espiculadas (p = 0,001) e diâmetro maior do NPS (p = 0,001; OR = 2,62 para diâmetro >20 mm). O modelo probabilístico de 1997 mostrou-se superior ao de 2007 - área sob a curva [ASC] ROC = 0,79 ± 0,44 (IC95%: 0,70-0,88) vs. ASC = 0,69 ± 0,50 (IC95%: 0,59-0,79). CONCLUSÕES: Idade elevada, maior diâmetro do NPS e presença de margens espiculadas tiveram associações significantes ao diagnóstico de malignidade do NPS. Nossa análise mostrou que, embora os dois modelos matemáticos sejam eficazes na determinação de malignidade do NPS nessa população, o modelo de 1997 mostrou-se superior.


OBJECTIVE: To analyze clinical and radiographic findings that influence the pathological diagnosis of solitary pulmonary nodule (SPN) and to compare/validate two probabilistic models for predicting SPN malignancy in patients with SPN in Brazil. METHODS: This was a retrospective study involving 110 patients diagnosed with SPN and submitted to resection of SPN at a tertiary hospital between 2000 and 2009. The clinical characteristics studied were gender, age, presence of systemic comorbidities, history of malignancy prior to the diagnosis of SPN, histopathological diagnosis of SPN, smoking status, smoking history, and time since smoking cessation. The radiological characteristics studied, in relation to the SPN, were presence of spiculated margins, maximum transverse diameter, and anatomical location. Two mathematical models, created in 1997 and 2007, respectively, were used in order to determine the probability of SPN malignancy. RESULTS: We found that SPN malignancy was significantly associated with age (p = 0.006; OR = 5.70 for age > 70 years), spiculated margins (p = 0.001), and maximum diameter of SPN (p = 0.001; OR = 2.62 for diameters > 20 mm). The probabilistic model created in 1997 proved to be superior to that created in 2007-area under the ROC curve (AUC), 0.79 ± 0.44 (95% CI: 0.70-0.88) vs. 0.69 ± 0.50 (95% CI: 0.59-0.79). CONCLUSIONS: Advanced age, greater maximum SPN diameter, and spiculated margins were significantly associated with the diagnosis of SPN malignancy. Our analysis shows that, although both mathematical models were effective in determining SPN malignancy in our population, the 1997 model was superior.

ABSTRACT

Biópsia percutânea dirigida por tomografia computadorizada tem sido amplamente utilizada como um procedimento efetivo e seguro para obtenção de diagnóstico histológico em muitas situações clínicas e em diversos órgãos. No pulmão, a biópsia percutânea tornou-se uma das principais escolhas para investigação de nódulos e massas. Sua versatilidade permite o acesso de lesões nas diversas localizações do pulmão, podendo ser utilizada para lesões periféricas e profundas mesmo de pequenas dimensões. Discutiremos as indicações, os aspectos técnicos do procedimento e os índices esperados de sucesso e complicação das biópsias percutâneas de nódulos e massas pulmonares.


Computed tomography-guided needle biopsy has been widely utilized as an effective and safe diagnostic procedure in many clinical settings. In the lungs, transthoracic needle biopsy has become one of the primary choices to investigate nodules and mass lesions. The procedure versatility allows access to either peripheral or central lesions at almost any site, even in cases of small nodules. In this article, indications, technical aspects of the procedure, expected success and complication rates of computed tomography-guided transthoracic needle biopsy of pulmonary nodules and masses are discussed.

ABSTRACT

JUSTIFICATIVA E OBJETIVOS: O nódulo pulmonar solitário (NPS) é definido radiologicamente como uma le­são pulmonar intraparenquimatosa com menor que 3 cm de diâme­tro e que não está associada com atelectasia ou adenopatia. Destes nódulos, 90% são achados radiológicos incidentais. O objetivo deste estudo foi discutir as causas e característi­cas dos NPS e como proceder com a investigação. CONTEÚDO: A abordagem do paciente com um NPS deve basear-se na estimativa da probabilidade de câncer, de acordo com o tamanho do nódulo, a presença de tabagis­mo, a idade do paciente e as características das margens do nódulo na tomografia computadorizada (TC). Exames de imagem modernos, como a TC dinâmica, a tomografia com emissão de pósitrons (PET) e a biópsia com agulha guiada por TC são altamente sensíveis na identificação do NPS, mas a especificidade dos exames de imagem é variável e geralmente baixa. CONCLUSÃO: O objetivo da avaliação do NPS é a pronta identificação de todos os pacientes com nódulos malignos, bem como evitar toracotomias em pacientes com nódulos benignos.

ABSTRACT

Normalmente as metástases pulmonares apresentam-se como nódulos múltiplos, bilaterais e distribuídos perifericamente. A presença de múltiplos nódulos pulmonares assintomáticos é uma condição que, muitas vezes,impõe dificuldades quanto à investigação diagnóstica até mesmo a médicos experientes. Embora a principal hipótese frente a este quadro imaginológico seja o de doença metastática, etiologias diferentes podem levar aquadros similares, dentre elas: infecções granulomatosas, sarcoidose, granulomatose de Wegener (GW), neoplasias benignas, artrite reumatóide, síndrome de Churg-Strauss e hamartomas múltiplos. No presente trabalho, são apresentados dois casos de patologias distintas identificadas incidentalmente por exames imaginológicos que inicialmente simularam metástases pulmonares em pacientes assintomáticos. Em um deles fez-se o diagnóstico de linfangioleiomiomatose pulmonar e o tratamento vem sendo feito com tamoxifeno 20mg/dia há um ano e quatro meses, com lesões inalteradas. O segundo revelou tratar-se de vasculite linfocítica compatível com GW, sendo tratado com pulsoterapia com prednisolona, ciclofosfamida e azatioprina e encontra-se no momento com um nódulo residual calcificado.

ABSTRACT

The aim of this study was to assess the diagnostic potential of [18]F-FDG Positron Emission Tomography imaging in the evaluation of patients with solitary pulmonary nodules, by comparing the diagnostic criteria in single time point imaging method to two different diagnostic criteria in dual-time-point imaging. This retrospective study was conducted in the Hospital of the University of Pennsylvania, and data was collected and analyzed in the period from September 2005 to March 2006, from the pooled hospital studies for the last eight years. Two hundred sixty five patients were included [161 men, 104 women, age range: 41-92 years]. All had solitary pulmonary nodules on computed tomography, and the diagnosis was confirmed by biopsy or by follow up computed tomography. All 265 patients underwent whole body FDG PET scan, and 255 of them had PET scan two time points. The maximum standardized uptake values of nodules were calculated for both time points. On single time point imaging we set the maximum standardized uptake value of 2.5 as a cutoff criterion for malignancy. On dual time point imaging, first criterion of malignancy was set as any increase in the maximum SUV from the first to second time point. The second criterion was set as either no change or increase in the maximum standardized uptake value between the two time points. Sensitivity, specificity and accuracy were calculated for the three methods by using the biopsy results and clinical follow up as gold standard. Biopsy and follow-up revealed 72 patients with malignant lung nodules, whereas 193 patients had benign nodules. Single time point imaging with a threshold maximum standardized uptake value of 2.5 had a sensitivity, specificity and accuracy of 63%, 92% and 85% respectively. On dual-time-point imaging, for the initial criterion for malignancy, the sensitivity, specificity and accuracy were 81%, 95% and 91% respectively. On dual time point imaging, for the second criterion for malignancy, the sensitivity, specificity and accuracy were 92%, 93%, and 92% respectively. Dual-time-point FDG PET imaging using both criteria has higher sensitivity, specificity and accuracy compared to single time imaging. Dual-time-point FDG PET imaging should be included in the clinical workup of patients with pulmonary nodule

ABSTRACT

Clear cell tumor of the lung is a rare and very unusual benign pulmonary tumor. As clear cell tumor of the lung contains abundant cytoplasmic glycogen, this tumor is called "sugar tumor". We report a case of sugar tumor in a 64-yr-old man presenting as a round pulmonary nodule. On dynamic computed tomography (CT) scans, the solitary pulmonary nodule showed early wash-in enhancement with an early washout pattern like a lung malignancy. The patient underwent wedge resection for the tumor. Pathologic examination, including immunohistochemical studies, revealed that the nodule was a benign clear cell tumor, so-called "sugar tumor". Because only a small number of cases have been reported previously, clinical aspects, radiological characteristics on dynamic contrast-enhanced CT, and differential diagnosis of the tumor are not well established. Herein we present a clear cell tumor of the lung and discuss the clinical, radiological, and pathological features of the tumor.

ABSTRACT

Doença de Castleman é uma doença rara que se manifesta geralmente como nódulo mediastinal, com grande variabilidade de apresentação em relação a idade, manifestações clínicas e evolução. Descreve-se paciente do sexo feminino de 40 anos de idade, com dor torácica incaracterística há alguns anos, com imagem hipotransparente à direita em raio X de tórax. A tomografia computadorizada e a arteriografia pulmonar não elucidaram o diagnóstico. O mesmo só foi possível ao exame anatomopatológico após ressecção cirúrgica do nódulo, que evidenciou características de hiperplasia angiofolicular ou doença de Castleman. O artigo ressalta a importância de se acrescentar esta doença na lista de morbidades para diagnóstico diferencial em nódulos pulmonares solitários.


Castleman disease is a rare disorder generally characterized by a mediastinal nodule, with a great variety of alternative presentations regarding age, clinical manifestations and evolution. This case report describes a 40-year-old female patient presenting with uncharacteristic chest pain for a few years. A chest X-ray revealed a hypotransparency on the right side. Computed tomography and pulmonary arteriography did not elucidate the diagnosis, which was made through surgical resection and anatomopathological examination of the nodule, which presented characteristics of angiofollicular hyperplasia, or Castleman disease. This article emphasizes the importance of adding this disease to the list of morbidities in the differential diagnosis of pulmonary solitary nodules.

ABSTRACT

El concepto de nódulo pulmonar solitario (NPS) corresponde a una imagen radiológica aumentada de densidad, en general esférica, de bordes bien delimitados, que mide menos de 3cm de diámetro.El NPS ha sido siempre una situación de difícil manejo, que requiere de un enfoque ordenado y especializado. Es por esto, que la aproximación diagnóstica en un paciente con NPS debe basarse en una estimación de la probabilidad de tener cáncer, de esta forma, cuando la posibilidad de cáncer sea baja, el nódulo puede ser seguido por medio de tomografía computada de alta resolución cada tres meses el primer año y cada seis el segundo. En caso de alta sospecha de cáncer, la resección quirúrgica es justificada, idealmente mediante videotoracoscopía. Para pacientes con nódulos indeterminados, puede utilizarse el PET para determinar el riesgo de cáncer. A raíz de los múltiples avances de la medicina y los nuevos métodos diagnósticos disponibles hoy en día, creemos importante revisar este tema entregando herramientas actuales y concretas para el estudio de un paciente con NPS.
