True aneurysm of the anterior tibial artery.

Most anterior tibial aneurysm cases described in the literature are pseudoaneurysms resulting from trauma. Since 1967, only 8 cases published on true anterior tibial artery aneurysms were atraumatic. Recent experience with an atraumatic aneurysm of the anterior tibial artery prompted a literature review regarding their incidence, and accordingly, we feel the need exists for greater recognition and understanding of this entity.
