摘　　要：目的探讨脑结核的CT表现特点。资料与方法经临床和/或手术病理证实的脑结核患者40例,治疗前均做CT检查。其中平扫加增强扫描36例,单纯平扫4例。结果 40例中,结核性脑膜炎32例,结核性脑膜炎并结核瘤4例,单纯性脑结核瘤和结核性脑脓肿各2例。32例结核性脑膜炎表现为脑底池明显强化,鞍上池变窄、闭塞,合并脑积水30例,脑梗死18例。6例脑结核瘤和2例结核性脑脓肿增强扫描呈结节状和环状强化,多数灶周有轻至中度脑水肿。结论根据临床和CT表现,多数可提示脑结核的诊断。Objective To explore the CT features of intracranial tuberculosis. Materials and Methods 40 patients with intracranial tuberculosis,all proved by clinical method and/or postoperative pathology,were collected. All cases were examinated with CT before treatment. Among them,there were 32 cases with tuberculous meningitis,4 cases with tuberculoma accompanied by tuberculous meningitis ,2 cases with pure tuberculoma and 2 cases with cranial tuberculous abscess. The pre-contrast CT scan were performed in all cases. Contrast enhancement CT were performed in 36 cases simultaneity. Results After the administration of contrast medium,there was homogeneous enhancement of basal cisterns in 32 cases with tuberculous meningitis. Narrow or obliteration of the the suprasellar cisterns was demonstrated. Hydrocephalus in 30 cases and cerebral infarctions in 18 case were found. Tuberculoma in 6 cases and tuberculous abscess in 2 cases appear as tubercle or ring enhancement. Conclusion Most of intracranial tuberculosis can be diagnosed according to clinical and CT features.
