[Supernumerary intrascrotal ectopic spleen: discontinuous splenogonadal fusion]

Splenogonadal fusion is a rare congenital malformation that results from abnormal connection of splenic tissue with the gonad or the mesonephric structures during embryonic development. It is usually detected in males and is classified into two types, continuous and discontinuous. We present the case of a 3-year-old boy with an asymptomatic scrotal mass that was suspicious for discontinuous splenogonadal fusion on Doppler ultrasonography. The diagnosis was confirmed by surgical excision and histological analysis. Splenogonadal fusion is a benign anomaly that has sometimes led to unnecessary orchidectomy because of suspicion that the mass represented a malignant tumor. Consequently, it is essential to include this malformation in the differential diagnosis of scrotal masses in children.
