Splenogonadal fusion presenting as a scrotal mass

Abstract

Splenogonadal fusion is an extremely rare congenital anomaly in which there is fusion between the spleen and gonad or derivatives of the mesonephros. Due to its extreme rarity, surgeons and radiologists lack the awareness enough to diagnose and sometimes even suspect the diagnosis, and most of the cases are discovered incidentally during various inguinoscrotal procedures. Asymptomatic inguinoscrotal mass is the most common presentation in children, and cryptorchidism is the most common associated anomaly. We present a case of splenogonadal fusion in a two years old child who was referred to our institution principally with right sided undescended testis. A left sided scrotal mass was found during examination, and this finding prompted us to conduct a thorough clinical evaluation. Preoperative diagnosis was not possible in this case and testicular tumor was the provisional diagnosis. Testicular sparing approach with biopsy of the lesion and histopathological examination helped to confirm the diagnosis and salvage the testis.
