Dorsalis pedis artery pseudoaneurysm: an uncommon cause of soft tissue mass of the dorsal foot in children.

Pseudoaneurysm of the dorsalis pedis artery is an extremely rare entity with only 3 pediatric cases previously presented in the English literature. We describe a new case and discuss the clinical presentation and surgical management. A 6-year-old boy was referred to our clinic because of a pulsatile tumor of the right dorsal foot increasing in size. A focused history found a low grade trauma to the dorsal foot one year previously. Magnetic resonance imaging revealed a pseudoaneurysm of the DPA. Resection of the pseudoaneurysm was completed without complications. Pseudoaneurysm of the DPA is a very uncommon cause of soft tissue mass of the dorsal foot. It can appear after low grade trauma. Treatment is surgical.
