Abstract

An 84-year-old man with history of left forehead melanoma was found on a restaging F-FDG PET/CT scan with hypermetabolic lung nodules and a mildly FDG-avid soft tissue nodule posterior to the umbilicus. Biopsy of a right lower lobe nodule revealed metastatic melanoma. Follow-up posttreatment PET/CT scan showed complete resolution of lung nodules and unchanged FDG uptake at the level of the umbilicus. Review of the patient's medical history revealed a remote history of umbilical hernia repair. We present a case of postsurgical plugoma mimicking the appearance of melanoma metastasis on FDG PET/CT.

摘要

一位 84 岁男性，有左侧额部黑色素瘤病史，在 restaging F-FDG PET/CT 扫描时发现肺部高代谢结节，脐后有轻度 FDG 摄取的软组织结节。右下肺结节活检显示转移性黑色素瘤。治疗后随访 PET/CT 扫描显示肺部结节完全消退，脐水平 FDG 摄取无变化。回顾患者病史，发现有脐疝修补的既往史。我们报告了一例术后 Plugoma 在 FDG PET/CT 上模拟黑色素瘤转移的外观。
