We report the F-18 FDG PET-CT appearance of recurrent gliosarcoma (GS) with extracranial extension in a 47-year-old man who underwent surgical resection of a right frontal GS 5 months earlier. F-18 FDG PET demonstrated moderate uptake in the recurrent disease. GS is a very rare, biphasic primary neoplasm of the central nervous system, composed of glioblastoma multiforme mixed with a sarcomatous component. It occurs in adults of middle age and carries a poor prognosis. The median survival reported is less than a year. The results suggest that F-18 FDG PET imaging may be useful in detecting recurrent GS.
我们报告了一名47岁男性复发性胶质肉瘤(GS)伴颅外扩展的F-18 FDG PET-CT表现,该患者5个月前接受了右额叶GS的手术切除。F-18 FDG PET显示复发性病变有中度摄取。GS是一种非常罕见的中枢神经系统双相原发性肿瘤,由多形性胶质母细胞瘤与肉瘤成分混合组成。它发生于中年成年人,预后较差。报告的中位生存期不到一年。结果表明,F-18 FDG PET成像可能有助于检测复发性GS。
