摘　　要：目的探讨颅内结核病的MSCT表现及其分型。方法回顾性分析25例颅内结核病患者的临床和CT资料,所有患者均经临床和脑脊液检查确诊。CT检查采用平扫和双期增强扫描。增强扫描采用动脉期、延迟期(延迟5 min)双期扫描。结果 25例患者中,脑膜型结核14例;脑实质型结核7例,其中脑结核瘤5例,结核性脑脓肿2例;混合型结核4例。增强后动脉期CT表现:颅内动脉血管充盈良好,结核病灶仅轻度强化;延迟期CT表现:结核病灶仍持续明显强化,颅内血管影已基本上不显示,病灶显示清晰。结论 MSCT可为颅内结核的临床诊断、分型、治疗提供可靠依据。Objective To investigate the MSCT （Multi-Slice Computed Tomography） features and classification of intracranial tuberculosis. Methods Clinical materials and CT data of 25 patients who had been confirmed as intracranial tuberculosis clinically and through cerebrospinal fluid examinations were analyzed retrospectively. MSCT with flat and dual-phase （arterial phase and delayed phase with 5-minute delay） enhancement scanning were carried out. Results Among 25 cases of patients, there were 14 cases with tuberculosis meningitis; 7 cases with brain parenchyma tuberculosis （including 5 brain tuberculoma and 2 with tuberculous brain abscess） and 4 cases with mixed cerebral tuberculosis. The enhanced artery-phase CT features included the well-filled intracranial artery and mildly-enhanced tuberculosis lesions. The enhanced delay-phase CT features included the constantly significantly-enhanced tuberculosis lesions, none-display of intracerebral arteries and clear display of lesions. Conclusion MSCT could provide reliable foundations for clinical diagnosis, clarification and treatment of intracranial tuberculosis.
