The authors describe the clinical and pathological features of a solitary fibrous tumor of the tentorium, a rare location for the tumor in the CNS. A 52-year-old lady presented to the neurosurgical services with headache of four months and vertigo of one and a half months duration. On examination, she had left-sided cerebellar signs and bilateral papilloedema. Cranial MR imaging showed an enhancing tumor based on the left tentorium. Clinical impression was a meningioma. The patient underwent left suboccipital craniectomy. The tumor was firm and vascular, extending above the tent through a defect. Total excision was achieved. The correct diagnosis of solitary fibrous tumor could be made only by histopathology. Solitary fibrous tumors of the tentorium, though rare, should be included in the differential diagnosis of dural based masses.
作者描述了小脑幕孤立性纤维瘤的临床和病理特征，该肿瘤在中枢神经系统中是一种罕见的部位。一名52岁女性因持续四个月的头痛和一个半月的眩晕症状前往神经外科就诊。检查发现，她有左侧小脑体征和双侧视乳头水肿。头颅磁共振成像显示左侧小脑幕有一个强化肿瘤。临床诊断为脑膜瘤。患者接受了左枕下颅骨切除术。肿瘤质地硬且有血管，通过一个缺损延伸至小脑幕上方。实现了肿瘤全切。只有通过组织病理学才能做出孤立性纤维瘤的正确诊断。小脑幕孤立性纤维瘤虽然罕见，但在硬膜下肿块的鉴别诊断中应予以考虑。
