A 45-year-old man presented with a headache. The medical history included a partial thyroidectomy, a colon polypectomy, and stomach tumors (all benign adenomas) 34, 2, and 1 year earlier, respectively. CT showed a space-occupying lesion in the left cerebellar hemisphere with calcification. The mass showed a striated pattern of hyperintensity on T2-weighted images. An FDG-PET scan was performed after the intravenous administration of 250 MBq (6.8 mCi) F-18 FDG. The images of the brain showed a hypermetabolic area in the left cerebellar hemisphere. The whole body images showed no abnormal accumulation other than physiologic uptake. A presumptive diagnosis of Lhermitte-Duclos disease (LDD) was made.
一名45岁男性因头痛就诊。病史包括分别于34、2和1年前进行的部分甲状腺切除术、结肠息肉切除术以及胃肿瘤（均为良性腺瘤）。CT显示左小脑半球有占位性病变伴钙化。该肿块在T2加权图像上呈条纹状高信号。静脉注射250 MBq（6.8 mCi）F-18 FDG后进行了FDG-PET扫描。脑部图像显示左小脑半球有高代谢区。全身图像除生理性摄取外未显示异常聚集。初步诊断为Lhermitte-Duclos病（LDD）。
