Calcification such as psammoma body is sometimes found especially in spinal cord meningioma but ossification of the meningeal tumor was rarely observed. Two cases of ossificated spinal cord meningiomas, located extramedullary intradurally apart from spinal bone, were clinicopathologically analyzed. The patients were 75-year-old female with meningioma at T9-10 level and 60-year-old female with one at T6-8 level. With pathological examination, concentration of psammoma bodies is not related to the formation of bone tissue. Metaplasia of arachnoid cell is seemed to be the origin of the bone structure.
有时会发现钙化，如砂粒体，尤其是在脊髓脑膜瘤中，但脑膜瘤的骨化很少见。对两例位于髓外硬膜内、远离脊椎骨的骨化性脊髓脑膜瘤进行了临床病理分析。患者分别为一名75岁女性，其T9 - 10水平患有脑膜瘤，以及一名60岁女性，其T6 - 8水平患有脑膜瘤。经病理检查，砂粒体的聚集与骨组织的形成无关。蛛网膜细胞化生似乎是骨结构的起源。
