A Case Report: Spinal Meningioma Indicating Extensive Calcification on X-ray

Abstract

Meningioma is a common benign tumor that accounts for about 25% of spinal neoplasms, rarely it is possible to detect see the presence of a mass shadow indicating calcification on X-ray in spinal meningioma. In this paper, we report a case in which we detected a calcification mass in spinal meningioma by simple X-ray with literature. A 73-year-old woman had low back pain and right calf pain in July 2003. She also noticed progressive muscle weakness below the anterior tibiolis. By a X-ray, we found the presence of a mass shadow indicating considerable calcification and spondylolisthesis at the level of the L4 vertebrae. We performed laminectomy from Th12 to L2 and from L4 to L5, and tumor resection. Histologically we diagnosed psammomatous meningioma, in terms of many variable-shaped psammomatous bodies against S-100 positive.
