We present benign high-flow priapism with intensive F-FDG uptake as an unusual finding in a case of testicular teratocarcinoma with a history of left orchiectomy and chemotherapy. F-FDG PET/CT scan showed pulmonary metastases, left obturator node involvement, and intense F-FDG uptake in the penis. Upon examination, the patient had a painless erection that lasted for couple of days. Because of pulmonary metastases, second-line chemotherapy regimen was started by his physician. The patient's priapism resolved spontaneously, with no episode of recurrence at 2 years' follow-up.
我们呈现了一例罕见的病例，即良性高流量性阴茎异常勃起，伴有强烈的 F-FDG 摄取，该病例为有左侧睾丸切除术和化疗史的睾丸胚胎癌。F-FDG PET/CT 扫描显示肺部转移、左侧闭孔淋巴结受累以及阴茎强烈的 F-FDG 摄取。检查时，患者出现无痛性勃起，持续了几天。由于肺部转移，他的医生开始采用二线化疗方案。患者的阴茎异常勃起自发缓解，2 年随访期间没有复发。
