X-ray computed tomography and sonography features of continuous splenogonadal fusion

Splenogonadal fusion is a rare congenital anomaly where the spleen is attached to either testicular or ovarian tissues. In present case, splenogonadal fusion presents as a large mass consciously connected to atrophic testis in left scrotum. The diagnosis of splenic gonadal fusion relies on radiologic and pathologic findings. Uniform density and vessels connection originating from splenic hilum between principle spleen and let testicle were observed with ultrasound and X-ray computed tomography (CT). Surgical exploration ruled out malignancy, extratesticular scrotal mass with affected testicle was removed. Pathologic examination demonstrated that ectopic spleen tissue and ipsilateral atrophic testis. Our data suggested that orchiectomy should be performed when contralateral testicle is normal and the affected testicular appeared significantly atrophy.
