Introduction: Osteochondromas are common benign bone tumors that can cause vascular complications, such as vessel perforation, thrombosis, and pseudoaneurysm formation. This case report presents a rare instance of popliteal vein thrombophlebitis caused by a tibial exostosis in a young adult.

Case Report: A 25-year-old patient presented with a swollen and red leg, initially diagnosed as thrombophlebitis of the left popliteal vein. Radiographic investigations revealed an exostosis on the posterior aspect of the proximal tibia, compressing both popliteal artery and vein. The patient underwent exostosectomy, and histopathological examination ruled out malignant transformation. At a 12-month follow-up, the patient demonstrated a favorable functional outcome.

Discussion: Vascular complications associated with exostosis are rare, with pseudoaneurysms being the most common. The popliteal artery is frequently involved due to its proximity to the knee and anatomical constraints within the Hunter's canal. Prompt diagnostic measures, including radiographs, Doppler ultrasound, and angiography, are crucial when vascular concerns arise in young patients. Surgical intervention is urgent, particularly in cases of arterial thrombosis. Controversy exists regarding preventive measures for vascular complications, with decisions influenced by factors such as arterial Doppler signs or contact with vessels.

Conclusion: Vascular complications associated with bone exostoses are rare but require prompt surgical treatment. Systematic removal of every exostosis near a vascular pathway should not be routine. However, abnormalities during clinical examination or concerning appearance should prompt an angioscan to assess relationships between vessels and the tumor, potentially leading to a recommendation for exostosis excision.
