脊髓肿瘤合并视神经乳头水肿和颅内压增高者少见,仅占脊髓肿瘤的3％,常被误诊。我院在经手术证实的80例脊髓肿瘤患者中发现了3例,为3.7％。此三例来我院前均被误诊。例1:女性14岁,腰骶部剧疼并向下肢放散10个月,曾诊断为“蛛网膜下腔出血”。治疗无效,1979年12月来我院就诊。入院检查双视乳头水肿,表现典型园椎马尾综合征。腰穿压力300mmH_2O,脑脊液微黄细胞数正常、蛋白200mmg％、糖及氯化物正常,Queck-ensted’s test 通畅,椎管造影见腰_2水平完全梗阻,呈倒杯口状充盈缺损。手术证实为园椎肿瘤,病理诊断为室管膜瘤。近全切除后一个月视乳头水肿消退,园椎马尾综合症恢复,术后辅以放疗随访2年8个月未见异常。例2:女性41岁,右上 Spinal cord tumors combined with optic nerve head edema and increased intracranial pressure were rare, accounting for only 3% of spinal cord tumors, often misdiagnosed. In our hospital, 80 cases of spinal cord tumors confirmed by surgery were found in 3 cases, 3.7%. All three cases were misdiagnosed in our hospital. Example 1: A 14-year-old woman with a lumbosacral pain and a 10-month excretion to the lower extremity was diagnosed as “subarachnoid hemorrhage”. Treatment is invalid, in December 1979 to our hospital. Hospital double check nipple edema, the performance of typical Park cauda equina syndrome. Lumbar puncture pressure 300mmH_2O, normal cerebrospinal fluid micro yellow cells, protein 200mmg%, normal glucose and chloride, Queck-ensted’s test patency, vertebral angiography see lumbar _2 level of complete obstruction, was inverted cup filling defect. Surgery confirmed Park tumor, pathological diagnosis of ependymoma. A month after subtotal resection, astigmatism edema subsided, Park cauda equina syndrome recovery, radiotherapy combined with radiotherapy follow-up of 2 years and 8 months showed no abnormalities. Example 2: Female 41 years old, upper right
