Persistent sciatic artery is a congenital vascular anomaly of the arterial
supply to the lower extremity. Thrombosis, distal embolization, aneurysmal
dilatation, and rupture of this vessel with compression of the sciatic
nerve have been recorded. Although rare in occurrence, complications of
persistent sciatic artery should be included in the differential diagnosis
of sciatic neuropathy. We present a case of an acute sciatic neuropathy
secondary to pseudoaneurysm formation of a persistent sciatic artery. We
demonstrate the diagnostic usefulness of magnetic resonance imaging.
