Feature of 18F-FDG PET-CT in mycosis fungoides: report of one case and review of literature
Pages: 363-365
Year: Issue:  6
Journal: Journal of Leukemia & Lymphoma

Abstract: 目的探讨18F-FDG PET-CT在蕈样肉芽肿(MF)分期、疗效评价及预后评估中的价值.方法分析1例MF在治疗前、治疗中和治疗后18F-FDG PET-CT显像结果及临床资料,并进行文献复习.结果患者为中年女性,因全身红斑肿块伴皮肤瘙痒4年,加重半年入院.头面部肿块活组织检查确诊为MF,治疗前PET-CT提示皮肤广泛受侵,全身多处淋巴结及双侧乳腺、心包及胰腺受累.治疗中PET-CT提示病灶18F-FDG代谢减低,病情部分缓解;而治疗中头颅磁共振成像(MRI)显示颅内淋巴瘤浸润,提示病情进展.改变化疗方案继续化疗,治疗后PET-CT提示全身未见18F-FDG代谢异常增高灶;患者出院后2个月复查头颅MRI,显示颅内新出现淋巴瘤浸润病灶,提示病情进展.后患者经过多次化疗及放疗,终因病情进展死亡.结论18F-FDG PET-CT在MF分期中具有重要的价值,而治疗中、治疗后PET-CT的疗效判断存在一定的假阴性,颅内浸润的MF患者仍需行头颅MRI以明确诊断.
