Ⅰ.はじめに
髄膜腫は神経膠腫についで多い頭蓋内腫瘍であるが,嚢胞を形成した髄膜腫に遭遇することはきわめてまれで,髄膜腫の1.218)−2.2%4)にすぎない.
嚢胞性髄膜腫についてわれわれが知りえた限りでは,44例が報告されており,このうち,本邦では川淵9)の1例をはじめとして15例が報告されているにすぎない.
Cystic changes are rare in meningioma. The authors reported two cases of the cystic meningioma.
1) The first case was 56-year-old female, whose complaints were motor weakness and hypesthesia on the right side. At the operation, a hen egg-sized tumor with a large cyst was removed totally from the left frontoparietal mid-convexity. Multiple cystic cavities were contamed in the tumor. Histologically the tumor was compatible with meningocytic meningioma with angiomatous component and showed numerous myxomatous degeneration and swollen vessel-walls.
