A large hemangiopericytoma was located posterocentrally. The patient presented with headaches and papilledema. Surgical management consisted of total gross excision by a combined right occipital transtentorial and right occipitoparietal transfalcine approach under magnification in three stages over a 6-week period. Removal was aided by dilatation of the right temperooccipital horn ("trapped ventricle") and meningioma-like encapsulation allowed separation of the tumor from the brain and surrounding structures after internal debulking of the tumor. Subsequent peritoneal shunting of the trapped ventricular horn and 5000 rads of radiotherapy were given to the patient. She remains well with an inferior quadrantanopsia on the left side more than 1 year after treatment. Meningiomas of the pineal region, the relationship of meningioma to hemangiopericytoma and malignant mesenchymal tumors (sarcomas) are considered in reference to presumed cells of origin.
一个巨大的血管外皮细胞瘤位于后中央。患者表现为头痛和视乳头水肿。手术治疗包括在6周内分三个阶段，通过联合右枕下入幕和右枕顶经镰状窦入路在显微镜下进行全瘤切除。通过扩张右侧颞枕角（“被困脑室”）辅助切除，肿瘤内部减压后，类似脑膜瘤的包膜使肿瘤与脑及周围结构分离。随后对被困的脑室角进行腹腔分流，并给予患者5000拉德的放射治疗。治疗后1年多，她情况良好，仅左侧有下象限视野缺损。参考假定的起源细胞，讨论了松果体区脑膜瘤、脑膜瘤与血管外皮细胞瘤及恶性间叶肿瘤（肉瘤）的关系。
