Intrabursal vein abrasion and thrombosis An unusual complication of femoral osteochondroma

the tibia.1 Complications are commonly associated with these exophytic masses and include cosmetic and osseous deformity, fracture, vascular compromise, neurologic sequelae, overlying bursa formation, and malignant transformation. Variants of osteochondroma include subungual exostosis, dysplasia epiphysealis hemimelica, turret exostosis, traction exostosis, bizarre parosteal osteochondromatous proliferation, and florid reactive periostitis. Although radiography is often diagnostic, additional imaging modalities including bone scintigraphy, ultrasonography, computed tomography, and magnetic resonance imaging is frequently employed in evaluation of these lesions, particularly when they are symptomatic or in unusual locations.2 Vascular complications associated with osteochondroma include vessel displacement, stenosis, occlusion, and formation of pseudoaneurysm.3 The aim of this report is to present a patient with clinical signs of right lower limb deep vein thrombosis (DVT) due to osteochondroma intrabursal vein thrombosis. The patient consented to publish medical information of her osteochondroma. Case report. In January 2008, a 21-year-old female was admitted to Dubai hospital with one week history of acute right leg pain that started, while she stood up from squatting position. Prior to this, she was perfectly fit and healthy. Her medical history was unremarkable and had no history of trauma. Examination of her right lower limb showed diffuse swelling on the medial aspect of mid thigh. The right thigh circumference was 57 cm compared to the left thigh of 48 cm and right calf was 46 cm against 38.5 cm on the left side. Neurological examination of both legs was normal and all distal pulses were felt. The x-ray of the right femur showed pedunculated osteochondroma located medially between middle and lower thirds of the femoral shaft. Complete blood count, creatine phosphokinase, prothrombin time, partial thromboplastin time, liver function test, creatinine, and glucose tests were normal, but D-dimer was 0.8 mg/L, then increased to on
