A 21 year old male who presented with painful enlargement of both the breasts and a hyperestrogenic state, was found to harbor a heterogeneous mass arising from the right adrenal on contrast enhanced Computed Tomography abdomen. The mass was hypermetabolic with no regional, nodal or distant metastases on Fluorine-18 Fluorodeoxyglucose Positron Emission Tomography /Computed Tomography examination. Notably, substantial tracer uptake was seen in bilateral gynecomastia. The patient underwent a right adrenalectomy with the histopathology report confirming adrenocortical carcinoma. This case demonstrates utility of FDG PET/CT in adrenocortical carcinoma. However, when interpreting FDG PET/CT as a staging tool in oncological male patients, one should consider gynecomastia as a possible cause for increased FDG uptake in the breast as it may lead to a false positive interpretation.
一名21岁男性，出现双侧乳房疼痛性肿大及雌激素过多状态，腹部增强计算机断层扫描（CT）发现右侧肾上腺有一异质性肿块。氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（FDG PET/CT）检查显示该肿块代谢活跃，无区域、淋巴结或远处转移。值得注意的是，双侧男性乳房发育处可见大量示踪剂摄取。患者接受了右侧肾上腺切除术，组织病理学报告证实为肾上腺皮质癌。本病例显示了FDG PET/CT在肾上腺皮质癌中的应用价值。然而，在将FDG PET/CT作为肿瘤男性患者的分期工具进行解读时，应考虑男性乳房发育可能是乳房FDG摄取增加的原因，因为这可能导致假阳性解读。
