title: Spontaneous inferior epigastric artery pseudoaneurysm.
abstract: A case of spontaneous pseudoaneurysm of the inferior epigastric artery-diagnosed on Doppler sonography-is presented. A 19-year-old boy presented with a lump in the anterior abdominal wall. Clinically a smooth, nontender, and noncompressible mass was present above umbilicus to the right of midline. A bruit was heard over the swelling. Doppler sonography demonstrated an oval hypoechoic structure in the right rectus sheath with turbulent flow. The pseudoaneurysm could be traced to the inferior epigastric artery. Surgical excision of pseudoaneurysm was performed. Histopathology showed myxoid changes in the wall of the pseudoaneurysm with no inflammatory changes.
