Splenogonadal fusion is an infrequent cause of testicular or scrotal swelling with less than 250 cases reported. We report the case of a 27-year-old male who presented with painless scrotal swelling. The sonography showed a homogeneous, well-encapsulated left extratesticular mass, which was surgically removed. The gross examination revealed a grey-brown tissue below the left testis. The microscopy of the grey-brown mass revealed splenic tissue, and the testis showed maturation arrest, resulting in the diagnosis of splenogonadal fusion. These can be easily mistaken for a tumor, especially in this age group. Reporting such an entity increases awareness among clinicians, radiologists and pathologists, which will aid in preventing an orchiectomy for these patients.
