【摘要】:正患者男,47岁,因"头痛2周"入院。全身检查未发现异常。血常规及血细胞计数正常,脑脊液细胞学检查示淋巴细胞比例85%,嗜酸性粒细胞1%。颅脑MRI示幕上及幕下脑实质内不均匀分布多个大小不等的结节,多数结节周围可见轻度水肿。与脑白质相比,结节表现出不同的MR信号特征(图1A~1C):(1)T1WI呈不均匀高信号,T2WI呈不均匀低信号,增强后中等
[Abstract]:Is 47 year old male patient, headache for 2 weeks before admission. Systemic examination found no abnormalities. Blood routine and blood counts were normal, cerebrospinal fluid cytology examination showed 85% of the proportion of lymphocytes, eosinophils 1%. brain MRI showed cerebral supratentorial and infratentorial uneven distribution in multiple sizes of the most nodules. Around the nodules visible mild edema. Compared with brain white matter, the nodules showed characteristics of different MR signals (Fig. 1A~1C): (1) T1WI shows high signal, T2WI showed inhomogeneous low signal, enhanced medium
