Chinese Abstract

Cryptorchidism is the absence of one or both testes from the scrotum. Confirmative diagnosis after adulthood is rare. A 21-year-old man was accidentally diagnosed with unilateral cryptorchidism after a whole-body FDG PET/CT scan for a health check-up. On the imaging, there was no physiological uptake in the left scrotum. On the contrary, a low grade FDG-avid lesion was noted in the left inguinal region. A follow-up urological ultrasound examination and monitoring confirmed the diagnosis. This case reminds us that an abnormal FDG uptake in a man's inguinal region should prompt us to consider examination of undescended testes to avoid misdiagnosing the case as some other lymphoid disease.

English Abstract

隱睪症是在陰囊中缺少一或兩個睪丸,成年後確診實屬罕見。一個21歲男性於全身氟化去氧葡萄糖正子斷層/電腦斷層造影之健康檢查中,意外診斷出單側隱睪症。影像中發現左側陰囊無睪丸,相反地,左側腹股溝有低度累積病灶。後續的病史詢問和泌尿科超音波檢查確定此診斷。它提醒我們,男性腹股溝出現氟化去氧葡萄糖異常攝取時應考慮隱睪症,以避免誤診為其他淋巴疾病。
