Deep vein thrombosis (DVT) is a condition classically associated with blood stasis, hypercoagulability, or injury to the vasculature. As blood stasis is usually associated with patient immobility, DVT occurrence in young active patients with no underlying haematological conditions is a rarity.
An exostosis, also known as osteochondroma, is a cartilage capped lesion. If solitary, they represent low malignant potential and unless symptomatic, they are rarely excised.
A 23 year old, active gentleman, presented to hospital with pain and swelling in the left lower leg. It was a deep, non-radiating pain, exacerbated by exercise. Wells' Criteria score for DVT was two. Ultrasonography identified thrombosis in the superficial femoral and popliteal veins. Haematological causes of thrombosis were out-ruled. X-ray showed a posterior femoral exostosis. It was determined that compression by the exostosis was the cause of the thrombosis.
DVT in this setting is uncommon with few reported cases identified in the literature.
We present a case of DVT secondary to osteochondroma formation in a young male. We also review the current literature and management of this rare entity.
