A rare case of left transverse testicular ectopia in an adult

Transverse testicular ectopia (TTE) is a rare congenital anomaly in which both testes descend into the same inguinal canal and are located in the same hemiscrotum. Diagnosing TTE can be challenging due to its rarity and unusual presentation.

The authors present a case of a male in his 50s who was diagnosed with left transverse testicular ectopia after presenting with an empty right hemiscrotum and two testes-like masses in the left hemiscrotum.

TTE usually presents with a history of an inguinal hernia and a contralateral undescended testis. However, in our case, the patient had both testes in the left hemiscrotum without an inguinal hernia, making this case even rarer.

Patients presenting with an empty hemiscrotum on one side and two testes-like masses on the other should be suspected of having TTE. In such cases, it is important to use imaging like USG or MRI, to identify and locate the ectopic site and assess the testicular morphology.
