Cystic meningiomas are uncommon tumors that are easily confused with metastatic or glial tumors that have cystic components. We have retrospectively reviewed all of the meningiomas operated on at the University of Puerto Rico in a 5-year period (1989-1993) and found only five cystic meningiomas (4.3% of total meningiomas). There is still debate about the etiology of the cyst wall; thus, multiple biopsies and frozen sections are recommended. Magnetic resonance imaging has improved diagnostic accuracy with its ability to demonstrate the dural attachment of the tumor.
囊性脑膜瘤是罕见肿瘤，很容易与具有囊性成分的转移性肿瘤或胶质瘤相混淆。我们回顾性研究了波多黎各大学在1989年至1993年这5年期间接受手术的所有脑膜瘤病例，仅发现5例囊性脑膜瘤（占脑膜瘤总数的4.3%）。关于囊肿壁的病因仍存在争议；因此，建议进行多次活检和冰冻切片检查。磁共振成像凭借其显示肿瘤硬脑膜附着情况的能力提高了诊断准确性。
