Trombosis venosa profunda secundaria a aneurisma de la arteria poplítea: caso clínico-radiológico y revisión de la literatura / Deep vein thrombosis secondary to popliteal artery aneurysm: literature review and presentation of case

Popliteal artery aneurysms is the most frequent peripheral aneurysm, predominantly affects men over 60 years of age and has a high morbidity associated to his complications, among which are ischemic complication, which can often end in amputation of the limb. Less frequent complications such as neuropathic and venous complications, particularly deep vein thrombosis, are equally relevant. Case presentation: Patient with an aneurysm of the popliteal artery complicated by thrombosis of the adjacent popliteal vein. Color Doppler ultrasound plays a fundamental role in the diagnosis.

Incontinencia urinaria de esfuerzo por osteocondroma familiar múltiple tardío / Urinary incontinence due to late multiple family osteochondroma

La osteocondroma múltiple familiar hereditaria es una enfermedad benigna, que por su posibilidad de malignización y el avance de sus deformaciones requiere controles periódicos. El objetivo del trabajo fue presentar un caso con diagnóstico de un tumor después de un largo periodo de tiempo de extirpación de su última lesión. Se presenta una paciente, de 62 años de edad, con antecedentes de osteocondroma múltiple familiar hereditaria desde los 8 años de edad. Es operada en varias ocasiones durante la infancia. Acude ahora por presentar incontinencia urinaria y aumento de volumen región vaginal, que aumentó en los últimos 8 meses. Antecedentes de la enfermedad en el padre, el hijo y la nieta. Se observan cicatrices en miembros y deformidades. Al tacto vaginal y rectal se encontró un tumor pétreo que ocupa la pared anterior y lateral derecha de la vagina. En estudios radiográficos y tomografía axial computarizada de abdomen se observa tumor en rama isquiopubiana derecha. La paciente fue operada y realizó la resección del tumor. La evolución fue satisfactoria. Anatomía Patológica informó tumor de 6 x 5 cm con actividad elevada de los condrotocitos. En la paciente destaca la aparición de un tumor de la misma enfermedad en la rama isquiopubiana, localización de baja frecuencia, el cual apareció 50 años después del último extirpado. La laparotomía extraperitoneal fue excelente para lograr la exéresis del tumor(AU)

Hereditary family multiple osteochondroma is a benign disease that requires systematic control on account of its possible malignization and advance of deformations. The objective of this paper was to present a patient diagnosed with a tumor after a long period of time elapsed from the excision of her last lesion. Here is a female patient aged 62 years, with history of hereditary family multiple osteochondroma since she was 8 years-old. She had been operated on several times in her childhood. She went to the hospital because she suffered urinary incontinence and volume increase in the vaginal region for the last 8 months. Her father, son and niece had the same problem. Scars and deformities were observed in limbs. On the vaginal and rectal exam, a stony tumor was found, which occupied the right anterior and lateral wall of the vagina. The radiographic studies and the abdominal CT showed a tumor in the right ischiopubic ramus. The patient was operated on to remove the tumor and her progress was satisfactory. The pathological anatomy report confirmed a 6 x 5 cm tumor with high activity of chondrocytes. In this patient, a tumor of the same disease located in the ischiopubic ramus occurred 50 years after the last excision of another tumor. The extroperitoneal laparatomy was an excellent method to achieve tumor excision(AU)

Osteochondrolipoma Presenting as a Popliteal Cyst

Here, we describe a popliteal mass that was initially misdiagnosed as a simple popliteal cyst, which finally turned out to be osteochondrolipoma. A 63-year-old housewife presented with sustained knee pain in association with a palpable mass on the popliteal fossa. The mass was in the posteromedial area and soft, non-tender, non-movable in the posteromedial area. Using plain radiography, the mass appeared as a round, soft tissue density lesion containing bony fragments. We performed an ultrasound-guided needle biopsy in conjunction with magnetic resonance imaging, followed by an open excisional biopsy. Microscopically, histological sections showed a lipoma with cartilaginous and osseous differentiation, finally diagnosed as osteochondrolipoma. In conclusion, popliteal masses are not always simple cysts, and the evaluation of masses in the popliteal fossa is always necessary.

Osteocondroma: diagnóstico radiológico, complicaciones y variantes / Osteochondroma: diagnostic imaging, complications and variants

Understanding and recognising the spectrum of appearances of osteochondroma is important because it represents the most frequent pseudotumoral bone lesion. There are pathognomonic radiological features that are evident with the currently available imaging methods. The recognition of these features and their potential complications and variants, enables a correct diagnosis to be made, the identification of possible complications and is a guide for the therapeutic decisions of non-conclusive cases.

Conocer el espectro de apariencias del osteocondroma es importante, ya que representa lesión pseudotumoral más frecuente del hueso y posee unas características radiológicas patognomónicas evidenciables con los distintos métodos de imagen disponibles actualmente. El reconocimiento de estas características radiológicas, de sus posibles complicaciones y variantes permite establecer el diagnóstico correcto, identificar las posibles complicaciones y guiar el manejo terapéutico de los casos no concluyentes.

Pseudoaneurisma de artéria poplítea secundário a osteocondroma femoral: relato de caso / Popliteal artery pseudoaneurysm caused by a femoral osteochondorma: case report

Osteochondromas are the most common benign tumor of the bone. They are sometimes responsible for vascular complications involving either veins or arteries, principally around the knee. Pseudoaneurysms are considered a rare condition. The authors describe the occurrence of a pseudoaneurysm of the popliteal artery in association with a femoral osteochondroma in a 30-years-old man.

Osteochondroma of the temporomandibular joint: a case report

Osteochondroma of the mandibular condyle has been found in the oral and maxillofacial region rarely. This paper describes a case of osteochondroma of the mandibular condyle in a 20-year-old woman, who was referred to our service with facial asymmetry, prognathic deviation of chin, cross-bite to the contralateral side, changes in condylar morphology, limited mouth opening, and malocclusion. Computed tomography (CT) was performed for better evaluation to the pathological conditions on the temporomandibular joint. Based on the clinical examination, patient history, and complementary exams, the hypothesis of osteochondroma was established. Condylectomy was performed using a preauricular approach with total removal of the lesion. After 3 years of postoperative follow up and orthodontic therapy, the patient is symptom-free, and has normal mouth opening with no deviation in the opening pattern.

Osteocondroma de côndilo mandibular é raro na região craniofacial. Este artigo descreve um caso de osteocondroma de côndilo mandibular em uma mulher de 20 anos que foi encaminhada ao nosso serviço apresentando assimetria facial, desvio de mento, mordida cruzada para o lado contralateral, alterações na morfologia condilar, limitação de abertura bucal e maloclusão. Tomografia computadorizada foi realizada para melhor avaliação da condição patológica da ATM. Devido à base no exame clínico, histórico do paciente e exames complementares, foi estabelecida uma hipótese de osteocondroma. Um procedimento de condilectomia utilizando abordagem preauricular com uma total remoção da lesão foi executado. Após três anos de acompanhamento pós-operatório e ortodôntico, o paciente está livre dos sintomas e tem uma abertura normal sem desvio de padrão durante a abertura.

Intrabursal vein abrasion and thrombosis: an unusual complication of femoral osteochondroma

A 21-year-old female with right distal femoral pedunculated osteochondroma is presented. She was admitted for severe lower limb pain, and swelling of one week duration. Clinical findings supported deep vein thrombosis [DVT] but Doppler ultrasound, and venography were normal. Surgical exploration revealed a large bursa around the tumor with a big vein abraded and thrombosed inside the bursa

Osteosarcoma arising from a solitary osteochondroma of the tibia

We present a case of osteosarcoma arising from an osteochondroma of the right tibia in a 71 year old man. The radiographic studies were suggestive of a malignant lesion. Histologic examination showed a conventional osteosarcoma that eroded the cartilagenous cap. The patient received postoperative chemotherapy with no evidence of metastasis until three years following the operation. The occurrence of osteosarcoma out of osteochondroma is an extremely rare event and very few cases have been reported

Hereditary multiple exostosis complicated by popliteal artery pseudo-aneurysm and common peroneal nerve palsy

We describe a rare case of a twenty-five-year old male patient with a history of hereditary multiple exostoses who presented with a right popliteal fossa swelling and right foot drop following a mild trauma. The swelling proved to be a popliteal artery pseudo-aneurysm complicating a femoral osteochondroma. The management and surgical treatment are discussed

Osteocondromas: avaliação por imagem das complicações / Imaging of osteochondroma complications

O osteocondroma é a entidade mais comum entre os diversos tumores ósseos conhecidos. Sendo uma lesão com alta capacidade expansiva e em certos casos com crescimento contínuo, pode determinar complicações, principalmente devido à ocupação de espaços que promove. Pode se apresentar de forma solitária ou múltipla, estando esta última relacionada à maior tendência para transformação sarcomatosa, que é a complicação mais temida. O objetivo do presente estudo édemonstrar, por meio de um ensaio iconográfico, as complicações mais comuns causadas pelos osteocondromas, correlacionando seus aspectos clínicos e radiológicos.

Osteochondroma is the most common entity beyond all the known osseous tumors. It is a lesion with a high enlargement capacity and a continuous growing in some cases, and it may determine complications, mainly due to mass effect. It may be present in a solitary or multiple forms, and the last one is related with a higher tendency to sarcomatous transformation, which is the most frightening complication. The purpose of the present study is to demonstrate, through an iconographic assay, the most common complicationscaused by the osteochondromas, making the correlation of its clinical and radiological aspects.

Extraskeletal Osteochondroma of the Buttock

Osteochondromas are common and typically arise from the metaphyseal ends of long bones. An osteochondral neoplasm of the soft tissue, which is a lesion of uncertain pathogenesis, is uncommon and usually arises from the synovial tissue in joints and tendon sheaths. Rarely, extraskeletal osteochondromas also arise outside of synovial compartments. Most of the reported cases were presented in the hands and feet, especially in the fingers. Here we describe a 44-yr-old female patient who presented with a pain in the left buttock. A well-defined osseous mass was detected in the buttock. It consisted of sharply demarcated, mature hyaline cartilage that was covered with a fibrous capsule, which changed gradually into cancellous bone, more pronouncedly at the center. The diagnosis of an extraskeletal osteochondroma should be considered when a discrete, ossified mass is localized in the soft tissues. A case of pathologically proven extraskeletal osteochondroma of the buttock is presented with a literature review, magnetic resonance imaging, and radiological findings.
