Bilobed testicle diagnosed by ultrasound in a 9-year-old boy

Bilobed testis is an extremely rare congenital malformation, and even rarer on the right side. Only 7 cases have been reported in the literature. We describe the case of a 9-year-old boy with a right bilobed testicle confirmed on ultrasound and discovered incidentally as a mass on physical examination. The aim of our work is to consider the bilobed testicle as a differential diagnosis of a testicular mass despite its rarity and to show the importance of ultrasound and MRI for its definitive diagnosis to avoid unnecessary surgery.
