A case report of vanishing testicle: radiological diagnosis and short review

Abstract

Background Vanishing testicular syndrome is also known as testicular regression syndrome (TRS) is due to atrophy and disappearance of testis in the fetal life after the formation of the normal testis. It is a spectrum of disorders; clinical features are depending upon the stage of fetal or early neonatal life at which function of testicles ceases. Case presentation Young 40-year-old male patient came for a routine master health checkup. On clinical examination he had a nonpalpable left testis, Rest of the clinical examinations are unremarkable. Referred to ultrasound (USG), for testis localization reveals the absence of left testis in the left scrotal sac and inguinal canal. Further MRI of the scrotum reveals the feature of TRS. Conclusion TRS in the 4th-decade adult is rarely reported in the literature. The asymptomatic presentation shows the least possibility of neoplasm in TRS patients.
