Abstract

UNLABELLED

A 47-year-old male with a history of right sided orchidectomy for stage 1 seminoma 6 months previously, was referred for a FDG PET-CT scan for restaging of testicular cancer having experiencing left testicular discomfort. Abnormally increased glyoclytic metabolism of the left testis and the inferior scrotal sac was demonstrated on the initial FDG PET-CT study. Subsequent ultrasound showed subtle heterogeneous echotexture with mild hypervascularity and no focal lesion was identified. The patient was subsequently treated with antibiotics for a presumed diagnosis of orchitis. A progress FDG PET-CT study 2 months later confirmed the complete resolution of the increased glycolytic metabolism in the left testis and the inferior scrotal sac.

未标注

一名47岁男性，6个月前因I期精原细胞瘤接受了右侧睾丸切除术，因左侧睾丸不适前来接受氟代脱氧葡萄糖正电子发射断层扫描（FDG PET-CT）以进行睾丸癌再分期。最初的FDG PET-CT检查显示左侧睾丸和阴囊下部糖酵解代谢异常增加。随后的超声检查显示细微的不均匀回声纹理，伴有轻度血管增多，未发现局灶性病变。该患者随后因疑似睾丸炎接受了抗生素治疗。2个月后的FDG PET-CT复查显示左侧睾丸和阴囊下部糖酵解代谢增加完全消退。
