Between April 1983 and April 1991, we studied nine cases of intracranial meningioma with cystic change out of 100 intracranial meningioma patients. The incidence was 9%. The patient's ages ranged from 40 years to 75 years old. There were five men and four women, of them, three had intratumoral cysts, and six had peritumoral cysts. Histologically, 7 cases were diagnosed as meningothelimatous type, one as psammomatous and the other one as angioblastic type. All the tumors with cystic change in this series were greater than two centimeters in diameter. Because the morphology was indistinct, Nauta's type II cystic meningioma was easily misdiagnosed as glioma or metastatic tumors preoperatively. Microsurgery is the best way for complete removal of the cyst wall to prevent recurrence.
1983年4月至1991年4月期间，我们在100例颅内脑膜瘤患者中研究了9例伴有囊性变的颅内脑膜瘤。发病率为9%。患者年龄在40岁至75岁之间。男性5例，女性4例，其中3例有瘤内囊肿，6例有瘤周囊肿。组织学上，7例诊断为脑膜上皮型，1例为砂粒体型，另1例为血管母细胞型。本系列所有伴有囊性变的肿瘤直径均大于2厘米。由于形态不清晰，术前Nauta II型囊性脑膜瘤容易被误诊为胶质瘤或转移瘤。显微手术是完全切除囊肿壁以防止复发的最佳方法。
