Abstract

We report a rare case of a 60-year-old man with diffuse metastases in bilateral penile corpus cavernosum after radical nephrectomy for left renal carcinoma. F-FDG PET/CT demonstrated diffuse hypermetabolic lesions in bilateral penile corpus cavernosum, hypermetabolic tumor recurrences in left renal operation region, and left pulmonary metastasis. Biopsy confirmed penile metastasis from renal clear cell carcinoma. Diffuse penile metastatic carcinoma from renal cancer is extremely rare and associated with poor prognosis. F-FDG PET/CT is helpful for diagnosis of penis metastasis and accurate staging of primary cancer.

摘要

我们报告了一例罕见病例，一名 60 岁男性，左肾癌根治性肾切除术后双侧阴茎海绵体弥漫性转移。F-FDG PET/CT 显示双侧阴茎海绵体弥漫性高代谢病变，左肾手术区域高代谢肿瘤复发，左肺转移。活检证实为肾透明细胞癌阴茎转移。弥漫性阴茎转移性肾癌极为罕见，预后不良。F-FDG PET/CT 有助于诊断阴茎转移和准确分期原发性癌症。
