RESUMO

INTRODUCCIÓN: El quiste óseo aneurismático es una neoplasia benigna que aparece con mayor frecuencia en la segunda década de vida. Clínicamente se presenta como una masa que produce dolor y deformidad de la extremidad afectada; radiológicamente se caracteriza por lesiones líticas con tabicaciones internas y abombamiento de la cortical. Se presenta un caso donde se realizó un aloinjerto estructural para el tratamiento de esta patología. CASO CLÍNICO: Paciente de sexo masculino, de 18 años de edad; con historia de 5 meses de evolución de dolor e impotencia funcional de extremidad inferior derecha; al examen físico se evidenció masa de 15 x 6 cm en tobillo derecho. La radiografía simple demostró una lesión lítica de tercio distal de peroné con adelgazamiento e insuflación de la cortical. El examen histopatológico fue positivo para células gigantes de tipo osteoclasto, cambios simplásticos, estroma miofibroblástico y extravasación eritrocitaria; datos compatibles con quiste óseo aneurismático. EVOLUCIÓN: Se realizó la resección en bloque de la masa tumoral del peroné, para la reconstrucción se utilizó un aloinjerto estructural más estabilización con placa de compresión dinámica y tornillo transindesmal; se realizó además una reconstrucción ligamentaria utilizando la técnica de Watson Jones. El paciente tuvo una evolución favorable, a los 16 meses del procedimiento se observó consolidación completa, además de una función articular conservada; no se evidenció recidiva en los 5 años posteriores de control. CONCLUSIÓN: El quiste óseo aneurismático es una patología benigna que siendo tratada en etapas iniciales, conlleva un mejor pronóstico y requiere de la realización de procedimientos quirúrgicos menos complejos. En pacientes con tumores de gran tamaño no es posible la realización de tratamientos convencionales; siendo la resección en bloque más la colocación de aloinjerto y estabilización ligamentaria, una alternativa terapéutica válida que permita preservar la extremidad.(ua)


BACKGROUND: Aneurysmal bone cyst is a benign neoplasm that presents more frequently in the second decade of life. Clinically It manifests as a mass that causes pain and deformity of the affected limb; radiologically, it is characterized by lytic lesions with internal septations and bulging of the cortex. A case is presented where a structural allograft was performed for the treatment of this pathology. CASE REPORT: 18 year-old male patient, with 5 month history of pain and functional impotence of right lower extremity; physical examination revealed a 15 x 6 cm mass in right ankle. X-ray showed a lytic lesion in the distal third of the fibula, with thinning an insufflation of bone cortex. The histopathological report was positive for giant cells (osteoclast-like cells), symplastic changes, myofibroblastic stroma and erythrocyte extravasation; data compatible with aneurysmal bone cyst. EVOLUTION: An en-bloc resection of the fibular tumor was performed, for the reconstruction a structural allograft plus stabilization with dynamic compression plate and transindesmal screw was used; a ligament reconstruction was also performed using the Watson Jones technique. The patient had a favorable evolution, at 16 months complete consolidation in addition to a preserved joint function was observed; there was no recurrence in the 5 years after control. CONCLUSION: The aneurysmal bone cyst is a benign condition that if treated in initial stages, has a better prognosis and requires less complex surgical procedures. In patients with large tumors, conventional treatment is not possible; en bloc resection plus allograft placement and ligament stabilization, is a valid therapeutic alternative to save the limb.(au)

RESUMO

Pigmented villonodular synovitis (PVNS) is a rare benign condition that is locally aggressive and may destructively invade the surrounding soft tissues and bone causing functional loss of the joint and the limb. The knee is the most affected joint (range, 28% to 70%) but involvement of the bone is not a common feature seen at this site. We present a rare case of diffuse PVNS of the knee associated with subchondral cyst of the lateral femoral condyle. This posed a diagnostic dilemma because of bone invasion. The radiological image of synovitis was pathognomonic of PVNS but etiology of the osteolytic lesion was confirmed only on histopathology. The large osteochondral defect was eventually managed in a staged manner with bone grafting and osteochondral autograft transfer.

RESUMO

PURPOSE: This study reviewed the common conditions associated with displacement of inferior alveolar nerve canal. MATERIALS AND METHODS: General search engines and specialized databases including Google Scholar, Pub Med, Pub Med Central, Science Direct, and Scopus were used to find relevant studies by using keywords such as “mandibular canal”, “alveolar canal”, “inferior alveolar nerve canal”, “inferior dental canal”, “inferior mandibular canal” and “displacement”. RESULTS: About 120 articles were found, of which approximately 70 were broadly relevant to the topic. We ultimately included 37 articles that were closely related to the topic of interest. When the data were compiled, the following 8 lesions were found to have a relationship with displacement of mandibular canal: radicular/residual cysts, dentigerous cyst, odontogenic keratocyst, aneurysmal bone cyst, ameloblastoma, central giant cell granuloma, fibrous dysplasis, and cementossifying fibroma. CONCLUSION: When clinicians encounter a lesion associated with displaced mandibular canal, they should first consider these entities in the differential diagnosis. This review would help dentists make more accurate diagnoses and develop better treatment plans according to patients' radiographs.

RESUMO

OBJECTIVE@#To evaluate clinical effect of autogenous iliac bone graft in treating osteochondral lesion of the talus with subchondral cyst.@*METHODS@#Twenty-two osteochondral lesion of talus patients with subchondral cyst were collected from January 2011 to December 2014, including 18 males and 4 females aged from 34 to 58 years old with an average of (46.4± 6.9) years old. All patients manifested pain and swelling of ankle joint, 7 patients manifested partially limited activity of ankle joint, 2 patients manifested unstable of ankle joint, and 2 patients manifested poor force line of foot. All lesions located on the medial side of talus dome. The area of cartilage injury ranged from 64 to 132(101.6±27.1) mm2, and diameter of subchondral cyst ranged from 9 to 15(10.5±1.8) mm. VAS score and AOFAS score were used to evaluate pain releases and recovery of ankle joint function before operation, 12 and 24 months after operation. Healing condition of autograft was assessed under arthroscopy after removal of internal fixation at 1 year after operation.@*RESULTS@#All patients were followed up from 24 to 60 months with an average of(42.5±9.9) months. Postoperative MRI at 12 months showed autograft healed well but little cyst still seen. Bone grafting and talus healed well, and formation of fibrocartilage well under arthroscopy. Postoperative MRI at 24 months showed combination of bone grafting and surrounding bone well, and small cyst could seen but less than before. VAS score at 12 months after operation 2.8±0.8 was less than that of before operation 6.2±1.5, but had no differences compared with 24 months after operation 2.6 ±0.8 (>0.05). AOFAS score at 12 months after operation 83.0±5.6 was less than that of before operation 55.3±13.7, but had no differences compared with 24 months after operation 83.7±6.6(>0.05).@*CONCLUSIONS@#Autogenous iliac bone graft in treating osteochondral lesion of the talus with subchondral cyst could have a good synosteosis and fibrous cartilage on surface, and relieve clinical symptoms.

RESUMO

OBJECTIVE@#To evaluate the efficacy of autogenous bone marrow injection and elastic intramedullary injection in the treatment of bone cyst in children.@*METHODS@#From January 2012 to December 2016, 56 children with simple bone cyst were divided into two groups: autogenous bone marrow blood injection group and elastic intramedullary needle group. There were 28 cases in the autogenous bone marrow blood injection group, 16 boys and 12 girls, aged (7.7±1.9) years old, 10 cases of proximal humerus, 8 cases of proximal femur, 6 cases of proximal tibia and 4 cases of femoral shaft. In the elastic intramedullary needle group, there were 28 cases, 18 boys and 10 girls, aged(7.5±2.2) years old, 11 cases of proximal humerus, 7 cases of proximal femur, 5 cases of proximal tibia, 4 cases of femoral shaft and 1 case of distal femur. The treatment effect was evaluated by Capanna standard.@*RESULTS@#All the patients were followed up, including 17 to 35(25.6±4.2) months in the elastic intramedullary needle group and 19 to 35(27.4±4.8) months in the autogenous marrow blood injection group. According to Capanna's evaluation standard of bone cyst, 27 patients in the elastic intramedullary needle group were treated effectively(25 patients cured, 2 patients healed but some remained lesions), 1 patients recurred, 0 patient had no response to treatment; 18 patients in the autogenous bone marrow blood injection group were treated effectively(13 patients cured, 5 patients healed but some remained lesions), 8 patients of cyst recurred, 2 patients had no response to treatment; the difference between the two groups was statistically significant(<0.01). The overall cure time was calculated by the follow-up of 25 cases in the elastic intramedullary injection group and 13 cases in the autogenous marrow blood injection group. The cure time was(20.2±3.5) months in the elastic intramedullary injection group and(27.7±4.9) months in the autogenous marrow blood injection group. The difference was statistically significant(<0.05).@*CONCLUSIONS@#For the treatment of bone cyst in children, the therapeutic effect of elastic intramedullary needle is better than that of autogenous bone marrow blood injection, and the cure time is shorter.

RESUMO

Chondroblastoma is a rare benign tumor that produces giant cells and cartilage matrix. The tumor occurs in people between 10 and 25 years with slightly higher incidence in males. The condition occurs in the proximal epiphysis of the tibia and humerus, distal epiphysis of the femur, but its occurrence in the talus is relatively rare, accounting for 4% of the total number of chondroblastoma cases. Chondroblastoma is often misdiagnosed as a primary aneurysmal bone cyst, giant cell tumor, chondromyxoid, and lesion of a secondary aneurysmal bone cyst by fibrous dysplasia. The most commonly used surgical method for chondroblastoma is broad curettage with bone grafting. In general, an aneurysmal bone cyst is associated with a second degree chondroblastoma, which is approximately 20%. Chondroblastoma of the talus and secondary aneurysmal bone cysts can be misdiagnosed as primary aneurysmal bone cysts. This paper reports a case of a young male patient with chondroblastoma of the talus, which was initially misdiagnosed as an aneurysmal bone cyst with involvement of the talo-navicular joint.

RESUMO

El quiste óseo aneurismático es una lesión ósea benigna que se presenta a edad temprana; su comportamiento suele ser agresivo por lo cual, la resección quirúrgica y la prevención de su recidiva son los pilares fundamentales de el tratamiento. Presentamos el caso de una paciente de 6 años de edad residente en Gualaceo, Ecuador, con masa de crecimiento progresivo y deformante en el codo izquierdo. Por las características de los exámenes de imagen y el cuadro sintomático se dignostica quiste óseo aneurismático que fue tratado con cirugía de resección intralesional y terapia adyuvante (fresado de alta velocidad, coagulación térmica y crioterapia). Se confirmó el diagnostico mediante el estudio histopatológico posquirúrgico


The aneurysmal bone cyst is a benign osseous lesion of presentation at an early age whose behavior is usually aggressive, so its surgical resection and the prevention of its recurrence is the fundamental pillar for the treatment. We present the case of a girl of 6 years of age living in Gualaceo, Ecuador, with a mass of progressive and deforming growth in the left elbow. By characteristics in the imaging tests and clinical picture it was considered as an aneurysmal bone cyst which was treated with intralesional resection surgery and adjuvant therapy (high speed burr, thermal coagulation and cryotherapy). The diagnosis was confirmed with postoperative histopathological study

RESUMO

ABSTRACT Osseous tumors of the hindfoot are not usual in the literature, the diagnosis in these cases is difficult and can often go unnoticed. Besides that, surgery and reconstruction are complicated due to the complexity of the local anatomy, which makes these lesions even more challenging for the orthopedic oncological professionals. On the following article two cases of aneurysmal bone cyst of the hindfoot are reported, as well as the alternatives and peculiarities in conducting these cases according to the oncological principles. When the subject are hindfoot tumor lesions, the early diagnosis is extremely important, as well as the proper staging and the management of the case by the orthopedic oncological professional according to oncological principles.


RESUMO Os tumores do retropé são raros na literatura, o diagnóstico é difícil e muitas vezes é feito pelo profissional menos experiente. Acrescente-se a isso o fato de o tratamento cirúrgico e a reconstrução serem complicados pela intrincada anatomia local. Essas lesões são desafiadoras para o ortopedista oncológico. Relatamos dois casos de cisto ósseo aneurismático do retropé e nossas opções e particularidades na condução deles de acordo com os princípios oncológicos. Nas lesões tumorais do retropé é importante a suspeita diagnóstica precoce, bem como o estadiamento adequado e a condução do caso de acordo com os princípios oncológicos, preferencialmente pelo ortopedista oncológico.

RESUMO

This report presents a case of cervical pneumatocysts as an incidental finding on cone-beam computed tomography. Pneumatocysts are gas-containing lesions of unknown etiology. They usually present in the ilium or sacrum, adjacent to the sacroiliac joint. In the literature, 21 case reports have described cervical pneumatocysts. Cervical pneumatocysts should be differentiated from other lesions, such as osteomyelitis, osteonecrosis, and neoplasms, as well as post-traumatic and post-surgical cases. Computed tomography, cone-beam computed tomography, and magnetic resonance imaging are appropriate tools to diagnose cervical pneumatocysts.

RESUMO

PURPOSE: To evaluate osseous changes of temporomandibular joint (TMJ) in patients with rheumatoid arthritis (RA) using cone-beam computed tomography (CBCT) and to correlate the imaging findings with the severity of TMJ dysfunction, clinical findings, and laboratory findings. MATERIALS AND METHODS: This study consisted of 28 subjects, including 14 RA patients and 14 controls, who were scheduled to undergo CBCT imaging for the diagnosis of a complaint not related to or affecting the TMJ. The Fonseca's questionnaire was used to assess the severity of TMJ dysfunction. Rheumatoid factor (RF) and the erythrocyte sedimentation rate (ESR) were assessed in the RA patients. CBCT was then performed in all subjects and osseous TMJ abnormalities were assessed. RESULTS: According to the Fonseca's questionnaire, 14.3% of the patients had no TMJ dysfunction, while 50%, 21.4%, and 14.3% had mild, moderate, and severe dysfunction, respectively. RF was positive in 64.3% of patients, and the ESR level was high in 100%. Imaging findings revealed a statistically significantly higher prevalence of erosion (85.7%), flattening (89.3%), osteophyte formation (32.1%), subchondral cyst (32.1%), sclerosis (64.3%), and condylar irregularities (28.6%) in the RA patients than in the controls. No correlations were found between CBCT findings and the clinical findings, the severity of TMJ dysfunction, disease duration, or laboratory results. CONCLUSION: RA patients might show extensive osseous abnormalities with no/mild clinical signs or symptoms of TMJ dysfunction that necessitate TMJ imaging for these patients. CBCT is a valuable and efficient modality that can assess osseous TMJ changes in RA patients.

RESUMO

Aneurysmal bone cyst (ABC) is a rare non-neoplastic bone lesion that involves mostly the long bones and vertebrae and may occur very rarely in the craniofacial bones. ABCs may occur as secondary bony pathologies in association with various benign and malignant bone tumors and with fibrous dysplasia (FD). FD is a common non-neoplastic bony pathology mostly affecting craniofacial bones. Secondary ABC occurring in craniofacial FD is extremely rare, with only approximately 20 cases reported in the literature to date. Here, we report on a case of secondary ABC in a 25-year-old woman who has had a craniofacial deformity for over 10 years and who presented to us with a rapidly growing painful pulsatile mass in the right frontal region that began over 2 months prior to admission. On thorough examination of computed tomography and magnetic resonance imaging brain scans taken at two-month interval, an aggressive, rapidly enlarging ABC, arising from the right frontal FD, was diagnosed. The patient underwent preoperative embolization followed by gross total resection of the ABC and cranioplasty. The 6-month follow up showed no recurrence of the ABC, nor was any progression of the FD noticed.

RESUMO

Surgery for pathologic hip fracture poses significant challenges regarding the fixation of fracture and management of the original tumor lesion. An extensive destruction of the femoral neck and intertrochanteric region by benign or malignant lesions complicated by a pathological fracture generally necessitates total hip arthroplasty; however, in adolescents and young adults, preservation of the hip is preferable. We present a 14-year-old female patient, who sustained a pathological intertrochanteric fracture through a pre-existing aneurysmal bone cyst. Several operative interventions with internal fixation and bone graft were unsuccessful, and combined nonunion and progression of osteolysis around the compression hip screw eventually caused femoral head collapse, mimicking osteonecrosis. Hip preservation and resolution of the original tumor were achieved by free vascularized fibular graft.

RESUMO

Stafne bone defect or mandibular bone depression is defined as a bone developmental defect usually filled with soft or salivary gland tissue. Lingual posterior variant incidence is less than 0.5%. We reported a case of an 80 years old Asian female asymptomatic patient who underwent routine panoramic radiographic examination and a radiolucent area in mandible was noticed as an incidental finding, with initial provisional diagnosis of traumatic bone cyst, aneurysmal bone cyst and lingual mandibular bone defect. The patient was then referred to multislice computed tomography and magnetic resonance imaging. Computed tomography showed a hypodense area with discontinuity in mandible base. Magnetic resonance imaging demonstrated a hyperintense image eroding mandibular body in contact with submandibular gland, which corresponded to fatty tissue and due to these imaging findings, the final diagnosis was lingual mandibular bone defect. Although the defect is a benign lesion and interventional treatment is not necessary, radiolucencies in mandible should be detailed investigated, due to their radiographic features that can resemble to other intrabony lesions. Imaging examinations can provide great defect details, especially magnetic resonance imaging, which can allow the identification of glandular tissue continuity to the mandibular defect.(AU)


O defeito ósseo do Stafne ou o defeito ósseo da mandíbula é definido como uma cavidade óssea geralmente preenchida com tecido glandular salivar. A incidência de variante lingual posterior é inferior a 0,5%. Neste relato, foi descrito um caso de paciente de paciente de 80 anos, etnia asiática e assintomática que foi submetida a exames radiográficos panorâmicos de rotina no qual observou-se incidentalmente uma área radiolúcida na mandíbula. Os diagnósticos iniciais foram de: cisto ósseo traumático, cisto ósseo aneurismático e defeito ósseo mandibular. A paciente foi encaminhada para realização de tomografia computadorizada multislice e ressonância magnética. A tomografia computadorizada mostrou uma área hipodensa com descontinuidade na base da mandíbula. A ressonância magnética demonstrou uma imagem hiperintensa no corpo da mandíbula, em contato com a glândula submandibular, correspondendo a tecido adiposo. Devido a estes achados imaginológicos, o diagnóstico final foi de defeito ósseo mandibular. Embora este defeito seja uma lesão benigna sem necessidade de tratamento intervencionista, as radiolucências na mandíbula, por conta de sua semelhança com outras lesões intraósseas, devem ser devidamente investigadas. Os exames de imagem podem fornecer detalhes do defeito, especialmente imagens de ressonância magnética, que podem permitir a identificação da continuidade do tecido glandular ao defeito mandibular.(AU)

RESUMO

El Quiste Óseo Traumático de la mandíbula es una cavidad intraósea sin revestimiento epitelial, considerado Pseudoquiste. Ha recibido diversas denominaciones debido a su etiología y patogenia inciertas, como Quiste Óseo Traumático, Quiste Óseo Solitario, Quiste Óseo Idiopático, entre otros. Es una lesión asintomática, que a menudo se diagnostica accidentalmente durante el examen radiológico de rutina, como una radiolucencia unilocular con bordes festoneados cuando está localizado entre las raíces dentarias. Presentamos un caso raro de Quiste Óseo Traumático en la sínfisis mandíbular, identificado radiográficamente, en una paciente de 14 años sin historia clara de trauma, diagnosticado y tratado con éxito.


The Traumatic Bone Cyst of the mandible is an intraosseous cavity without an epithelial lining, considered a pseudocyst. It has received various names due to its uncertain etiology and pathogenesis, such as Traumatic Bone Cyst, Solitary Bone Cyst, Idiopathic Bone Cyst, among others. It is an asymptomatic lesion, which is often diagnosed accidentally during routine radiological examination, as a unilocular radiolucency with scalloped edges when located between the dental roots. We present a rare case of Traumatic Bone Cysts in the mandibular symphysis, identified radiologically, in a 14-year-old patient without clear history of trauma, diagnosed and successfully treated .

RESUMO

El quiste óseo aneurismático es una lesión expansiva, de pared fina, de contenido quístico, y con niveles líquido-líquido. Su etiología es incierta, suele asociarse a traumatismo, probablemente debido a obstrucción venosa o a la formación de fístulas que se producen tras la contusión. Los pacientes refieren dolor, que puede ser de comienzo insidioso o abrupto debido a una fractura patológica. Los quistes óseos aneurismáticos se clasifican, según su etiología, en primarios o secundarios a una lesión subyacente, como displasia fibrosa, condroblastoma, tumor de células gigantes u osteosarcoma. Se presenta el caso de una paciente que consulta por dolor localizado en la región plantar izquierda, no asociado a traumas, a quien se le diagnosticó un quiste óseo aneurismático, con hallazgos definitivos en resonancia magnética (RM) y comprobación histológica.


The aneurysmal bone cyst is an expansive, thin-wall lesion with cystic content, and with the presence of liquid-liquid levels. Its etiology is uncertain, usually associated with trauma, probably due to a venous obstruction or the formation of fistulas that are produced by contusion. Patients report pain, which may be of insidious onset or abrupt onset due to a pathological fracture. Aneurysmal bone cysts are classified according to their etiology in primary, or secondary to an underlying lesion, such as fibrous dysplasia, chondroblastoma, giant cell tumor or osteosarcoma. We present the case of a patient who consulted for pain located in left plantar region, not associated with trauma, who was diagnosed with an aneurysmal bone cyst, with definitive magnetic resonance findings and histological verification.

RESUMO

Background: Magnetic resonance imaging [MRI] is defined as one of the most important modalities used for diagnosing lesions of small and complex structures in the body [1]. We aimed to investigate the most common wrist pathologies detected by MRI in KAUH [King Abdulaziz University Hospital] in Jeddah


Methodology: A retrospective study was done with a total sample size of 127 individuals who underwent wrist MRI investigation at KAUH in Jeddah [Saudi Arabia], between 2010-2016. The data entry was performed by using Microsoft Excel 2014, and statistical analysis was performed by SPSS V21


Results: The results of the analysis showed that the most common wrist pathology was ganglion cysts, constituting 17.8% of the 157 findings we observed. Other common findings were Tenosynovitis [10.2%], TFCC [Triangular fibrocartilage complex] tear [10.2%], TFCC degeneration [5.7%] and subchondral cysts [3.8%]. There was also a significant relation between normal/abnormal findings in individuals and their age of presentation. Age mean was 29.27 [ +/- 7.46 SD] for those with normal findings, and 37.33 [ +/- 15.62 SD] for those with abnormal findings, [P value less than 0.001]. Regarding X-ray investigation, we found that most of the sample [65.4%] did not undergo X-ray prior to MRI


Conclusion: It has been found that there is variance between all findings that were discovered by MRI, that there are differences between our study and those of others, and that due to the different sorts of cases that were presented to the hospital. We also found that most of the individuals with wrist pathologies did not get X-rays before MRI, so we recommend a clear policy of ordering MRI, also proper history and examination should be the essential tool to reach hand and wrist diagnoses. That will help in saving resources

RESUMO

Ankle injury is one of the most common injuries, and osteochondral lesions of the talus occur in up to 70% of acute ankle sprains or fractures. The number of sports injuries have increased due to the increase in leisure activities, and the development of diagnostic techniques to evaluate the cartilage status leads to a higher prevalence of osteochondral lesions of the talus. Although osteochondral lesions of the talus with no symptoms can be treated conservatively, adult patients are usually treated by surgery because they are more likely to fail after non-surgical management. Recovery to normal cartilage is important, but there has been no surgical treatment established for effective cartilage regeneration. Bone marrow stimulation, such as arthroscopic microfracture, is a commonly used surgical procedure and an effective treatment for lesions that are small or failed after non-operative treatment. In addition, there are treatments, such as osteochondral autograft transplantation, osteochondral allograft transplantation and autologous chondrocyte implantation. The selection of the methods depends on the size and location of the lesion, the presence of subchondral cysts, and the results of previous surgery. Many surgical procedures have shown good results in short and mid-term follow-up studies but the results of long-term follow-up have been unclear. Various treatment methods, such as hyaluronan, platelet-rich plasma, mesenchymal stem cells, and bone marrow aspirate concentrate, have been available recently due to the development of various biological agents.

RESUMO

Los neumoquistes intraóseos, son lesiones cavitadas de contenido gaseoso, las cuales generalmente son encontradas como hallazgos incidentales en exámenes imagenológicos a nivel sacroiliaco, pubis, sacro, clavícula, cabeza humeral, columna cervical, torácica y en menor medida, en la columna lumbar. La tomografía computarizada es el examen de elección para realizar la confirmación diagnóstica y descartar diagnósticos diferenciales, y su patrón característico se describe como una lesión de aspecto quística con atenuación por gas intralesión con rangos entre -950 y -580 H. El diagnóstico diferencial debe incluir otras posibles causas de gas intraóseo como osteomielitis, osteonecrosis, quistes óseos o subcondrales, entre otros. Si bien la progresión natural del neumoquiste intraoseo es desconocida, distintos autores han descrito que en seguimientos radiológicos hasta 4 años, el tamaño de las lesiones se mantiene estable, e incluso en otros casos se han resuelto de manera espontánea, sin embargo, en otros se ha reportado un crecimiento progresivo en seguimiento de 16 meses. En cuanto al manejo del neumoquiste intraóseo, en la mayoría de los casos reportados se ha observado una evolución benigna, con manejo conservador de las lesiones, sin embargo frente a lesiones de gran tamaño con riesgo de fractura patológica se debe plantear la posibilidad de manejo quirúrgico con corpectomía e injerto óseo. Debido a la escasa evidencia respecto de esa lesión, es que se reporta un caso de neumoquiste vertebral lumbar, describiendo su estudio, evolución y manejo.


The intraosseous pneumatocyst, is a rare condition in which there is gas-filled cystic lesion in the bone which is incidentally discovered on imaging studies and has been observed in relation to iliosacral joint, the humeral head, medial end of the clavicle, cervical spine, and thoracolumbar spine. The computer tomography (CT) is the most useful radiological tool for the diagnosis of the pneumatocyst and the pathognomonic finding is a cystic-like lesion with attenuation that ranges from 950 to 580 Hounsfield units, indicating gas, surrounded by a sclerotic rim. Main differential diagnosis includes other possible causes of intraosseous gas such as infectious osteomyelitis, osteonecrosis, solitary bone cysts, and subchondral cysts. The natural progression of the intraosseous pneumatocyst is unclear. Some authors suggest that these lesions remained unchanged up to 4 years of follow up with CT, and even spontaneous resolution of the pneumatocyst have been reported, but others authors found progressive growth of the lesions in few weeks, months or years. Surgical treatment could be indicated in symptomatic patients or with progressive growth of the lesion at CT follow up that could increase the potential risk of vertebral fracture. We report a case of vertebral body intraosseous pneumoatocyst in lumbar spine describing the diagnosis process and management.
