Significance of ultrasonography in diagnosing transverse testicular ectopia: A case report

An uncommon congenital abnormality known as crossed testicular ectopia (CTE) or transverse testicular ectopia (TTE) occurs when both testes migrate into the same hemiscrotum. Inguinal hernia and persistent Müllerian duct syndrome are frequently associated with it. We present a case of "TTE" in a 1-year-old boy with an empty right hemiscrotum and left inguinal hernia. TTE, first described by Von Lenhossek, can be diagnosed via ultrasound, with over 100 cases reported. Theories of its origin include developmental anomalies of the genital ridge and Wolffian duct fusion. Accurate diagnosis is crucial due to increased malignancy risks and complications in management.
