Idiopathic pseudoaneurysm of the dorsalis pedis artery mimicking pigmentedvillonodular synovitis

Pseudoaneurysm of the dorsalis pedis artery is uncommon and is usually asso ciated with a history of trauma to the vessel. Without such a history, the diagnosis may be challenging, because the mass may be confused with other c ommon soft tissue masses in the foot. This case report describes a 67-year- old man with an idiopathic pseudoaneurysm of the dorsalis pedis artery that mimicked pigmented villonodular synovitis.
