Arteriovenous malformations commonly cause ulcers, but less emphasis has been placed on the fact that venous hypertension in the leg is responsible. We report the case of a 25-year-old man with a venous leg ulcer caused by an arteriovenous malformation, who presented with a painful left dorsal foot ulcer that had not healed for over a month. Contrast-enhanced computed tomography showed an arteriovenous malformation with a feeder from the three branches of the lower leg on the medial side of the ulcer. After three rounds of embolization and wound management, although arteriovenous malformations remained, the shunt volume was reduced, and the ulcer became epithelialized. It is important to distinguish arteriovenous malformations from venous leg ulcer-like lesions in young patients. We recommend performing multidisciplinary treatment, including embolization, at a specialized institution at an early stage.
