Angiolipoma on the Lumbar Spine

ABSTRACT

Angiolipomas are composed of mature adipose tissue and blood vessels. Spinal angiolipomas are rare benign tumors with a good prognosis, and most symptoms are due to progressive compression of the spinal cord and root. The treatment of choice is total resection without any additional therapy. We report a case of an epidural angiolipoma on the lumbar spine in a 69-year-old man with weakness of the lower extremities. Lumbar magnetic resonance images revealed a well-enhanced epidural mass. He underwent laminectomy, and the tumor was completely removed. Pathologic examination confirmed the tumor was an angiolipoma. The patient’s symptoms gradually improved postoperatively.
