Splenogonadal Fusion Associated With Bilateral Cryptorchidism, Presenting As An Operative Surprise

Splenogonadal fusion is a rare entity with approximately 150 reported cases until the year 2005. the entity is a rare congenital anomaly in which there is fusion of splenic and gonadal anlagen or mesonephric derivatives. splenogonadal fusion has two continuous and discontinuous types. about ten cases have been reported in association with bilateral cryptorchidism. very few cases have been diagnosed preoperatively. many cases present as a testicular swelling and undergo an unnecessary orchiectomy with the suspicion of a testicular neoplasm. herein, we report a new case of discontinuous splenogonadal fusion in a 29 year old man with bilateral cryptorchidism who underwent surgery. surprisingly two masses were noted adjacent to undescendent testis in left groin in operative room which were resected and proved to be a new case of splenogonadal fusion in histological exam.
