Traumatic pseudoaneurysm of the anterior tibial artery simulating soft tissue malignancy

Two patients presenting with false aneurysm of the anterior tibial artery are illustrated. Presentation was remote from the time of trauma and the diagnosis of neoplasm was initially considered in both because of the bony and soft tissue changes. The purpose of this report is to bring attention to the possibility of delayed vascular injury simulating tumor by describing the radiographic features of these two proven cases.
