Twenty-two cases of unusual intracranial meningioma associated with a cyst are reported and 144 published cases reviewed. The complex mechanisms leading to the formation of the cyst within the meningioma are analyzed on the basis of the surgical and histopathological evidence. The neuroradiological features (Computed Tomography and Angiography) which supply a correct preoperative diagnosis are discussed. It is clear from the literature how difficult preoperative diagnosis is, being possible only in 38% of cases with CT scanning and in 13% with angiography. It is necessary to remove not only the solid portion of the meningioma but also the cyst wall in order to prevent a recurrence. This is technically difficult for the type II intratumoural variety of Nauta's classification.
报告了22例伴有囊肿的特殊颅内脑膜瘤病例，并对144例已发表病例进行了回顾。根据手术和组织病理学证据分析了导致脑膜瘤内囊肿形成的复杂机制。讨论了有助于术前正确诊断的神经放射学特征（计算机断层扫描和血管造影）。从文献中可以清楚地看出术前诊断是多么困难，CT扫描仅在38%的病例中能够实现，血管造影则仅在13%的病例中可行。为防止复发，不仅要切除脑膜瘤的实体部分，还必须切除囊肿壁。对于Nauta分类中的II型肿瘤内囊肿，这在技术上具有挑战性。
