目的:探讨粟粒性脑结核瘤和脊髓结核瘤的MRI特点。方法:回顾性分析12例粟粒性脑结核瘤、5例脊髓结核瘤患者的MRI影像资料。结果:MRI平扫表现不典型,增强后粟粒性脑结核瘤表现为幕上幕下在大脑、脑干、小脑弥漫分布的小环状或结节状强化灶,大小趋向一致,约2 mm,可合并结核性脑膜炎及脑积水;脊髓结核瘤表现为脊髓内多发小环状或结节状强化灶。结论:粟粒性脑结核瘤和脊髓结核瘤MRI增强表现有一定特征性,平扫见到脑内或脊髓内多发水肿影患者应行增强检查。
Objective: To investigate the MRI features of miliary brain tuberculosis and spinal tuberculosis. Methods: MRI images of 12 patients with miliary brain tuberculosis and 5 patients with spinal tuberculosis were retrospectively analyzed. Results: The manifestations of MRI were not typical. Miliary tuberculoma showed enhanced distribution of small annular or nodular lesions in the brains, brainstems and cerebellum. Merged with tuberculous meningitis and hydrocephalus; spinal tuberculosis showed multiple intra-spinal cord or nodular enhancement. Conclusions: Mild tuberculoma and spinal tuberculoma MRI enhancement has some characteristics, to see the brain or spinal cord scan multiple edema shadow should be enhanced examination.
