Calcification of spinal cord tumors: report of two cases.

Two cases of calcification of spinal cord tumors were detected by computed tomography and magnetic resonance imaging. The first; a 27-year-old male, with a very rare astrocytoma accompanied by calcification of the thoracic spinal cord, and the second; a 62-year-old female, with a rare calcified neurilemmoma in the upper cervical extradural space. The purpose of this paper is to draw attention to the fact that some spinal cord tumors occasionally contain areas of calcification, and review the literature on this subject.
