【摘要】目的 探討粟粒性腦結核及與其需要鑒別疾病的MRI特點。方法 2007年12月-2009年10月，對11例粟粒性腦結核患者的MRI平掃及增強表現進行分析，總結其MRI特征性表現。結果病史上粟粒性腦結核多存在血行播散型肺結核，平掃表現為多發小片影，增強后表現為彌漫分布的小環狀或結節狀強化灶，大小趨向一致，多為2 mm左右，可合并結核性腦膜炎及腦積水。結論粟粒性腦結核的MRI平掃表現不典型，增強表現有一定特征性，認識其特點可以和其它常見的顱內多發病變進行鑒別。
【Abstract】 Objective To analyze the MRI appearances of cerebral military tuberculosis and other diseases that need to differentiate. Methods From December 2007 to October 2009, the MRI appearances of 11 cases on the plain scan and the enhanced MRI scan after injection of Gd-DTPA were reviewed and summarized. Results The cases of cerebral military tuberculosis usually had the history of military pulmonary tuberculosis, showed multiple lesions in fragments on plain scan, and the lesions distributed diffusely after enhancement, showed as ring form or nodosity. The size tended to be uniform, often 2 mm in diameter approximately. Tuberculosis meningitis and hydrocephalus could accompany. Conclusion The manifestation of plain MRI is not typical, and the enhancement MRI is imperative. Some characteristic appearances can be found after injection of Gd-DTPA, and these characteristic appearances could be helpful to differentiate with other multiple intracranial diseases.
