Angioma in the paraspinal muscles complicated by spinal epidural hematoma. Case report.

This case of angioma in the paraspinal muscles with extension into the epidural tissue was complicated by epidural hematoma in the thoracolumbar region. The hemorrhage was caused by rupture of the part of the angioma lying in the epidural tissue. A spinal bruit was of great value in diagnosing the angioma. Percutaneous embolization of the feeding arteries of the angioma reduced bleeding during surgery and contributed to successful surgical treatment.
