ANGIOLEIOMYOMA INVOLVING THE SCIATIC-NERVE - CT DEMONSTRATION CASE-REPORT

An angioleiomyoma adjacent to the sciatic nerve was responsible for an 11-year history of pain and dysfunction in the sciatic nerve distribu tion, which required numerous therapeutic procedures and intermittent use of narcotic analgesics. Diagnosis was finally made when results of a sciatic nerve block suggested possible mechanical compression of th e nerve and computed tomography examination of the pelvis was extended further caudad than usual, demonstrating the tumor adjacent to the sc iatic nerve near the ischial tuberosity. Only one previous case of ner ve dysfunction due to impingement by an angioleiomyoma has been report ed.
