囊性脑膜瘤极为罕见,本文报告两例。例1,女,15岁。因头痛2年入院。神经系统检查:双侧视乳头水肿及腱反射对称亢进。颅骨平片示蝶鞍扩大,颅骨冠状缝分离。左侧颈动脉造影示左额部有一大的无血管肿物。行左额、颞部开颅,在额叶表面有一囊肿,肉眼诊断为星形细胞瘤。从囊内抽出黄色液体约150ml后,囊肿变小,液体迅速凝固。囊壁表面光滑,囊肿壁外下方有一实体性富有血管的肿块,肿物全切除。病理检查为混合型脑膜瘤。例2,男,24岁。因头痛,右侧听力丧失及周围性面瘫而入院。神经系统检查:双侧视乳头水肿,右侧Ⅶ、Ⅷ颅神经受累,左侧肢体轻瘫,双侧腱反射亢进。右侧颈动脉造影示右额、颞肿物,有颈外动
Cystic meningiomas are extremely rare and two cases have been reported in this article. Example 1, female, 15 years old. He was admitted to hospital with a headache for 2 years. Nervous system examination: bilateral papilledema and tendon reflex symmetry hyperthyroidism. Skull flats show that the sella expands and the coronal sutures of the skull separate. The left carotid angiogram showed a large non-vascular mass in the left frontal area. Left frontal and orbital craniotomy, with a cyst on the frontal surface, astrocytoma diagnosed by naked eye. After about 150 ml of the yellow liquid was removed from the capsule, the cyst became smaller and the liquid quickly solidified. The surface of the capsule wall was smooth, and there was a solid, massive vascular mass below the cyst wall. The tumor was completely resected. Pathological examination was mixed meningioma. Example 2, male, 24 years old. He was admitted to hospital because of headache, right hearing loss and peripheral facial paralysis. Nervous system examination: bilateral papilledema, right VII, VIII cranial nerve involvement, left limb frivolous, bilateral tendon hyperreflexia. The right carotid angiogram shows the right frontal, orbital mass, and extracranial motion
