报道209例无定位体征高颅压综合征的CT所见。CT阳性者132例(63.2％),其中脑转移癌8例,脑囊虫11例,脑部炎症14例,脑积水、脑室对称性扩大18例,脑肿块66例,其他15例。CT阴性者77例(30.8％),其中61例符合良性高颅压(BIH)的诊断。这些病例与国外所见到的典型BIH似有不同,其原因有待进一步探讨。根据本文资料,以下各点常提示CT有阳性所见,尤应特别重视:(1)年龄≤9岁及≥60岁者;(2)病程在6个月以内者;(3)有视乳头水肿和(或)“软”体征;(4)脑电图(EEG)有重度及局灶异常者。
209 cases of non-location signs of intracranial hypertension syndrome seen in CT. CT positive in 132 cases (63.2%), including 8 cases of brain metastases, 11 cases of cerebral cysticercosis, brain inflammation in 14 cases, hydrocephalus, enlarged ventricular symmetry in 18 cases, 66 cases of brain tumor, the other 15 cases. There were 77 cases (30.8%) with negative CT, of whom 61 cases were diagnosed with benign intracranial hypertension (BIH). These cases seem to be different from the typical BIH seen abroad, for reasons to be further explored. According to the information in this article, the following points are often prompted to see a positive CT, especially should pay special attention to: (1) age ≤ 9 years and ≥ 60 years of age; (2) duration of less than 6 months; (3) Edema and / or “soft” signs; (4) EEG with severe and focal abnormalities.
