MRI findings of bilateral juvenile granulosa cell tumor of the testis in a newborn presenting as intraabdominal masses.

Juvenile granulosa cell tumor (JGCT) of the testis is a rare benign tumor that typically presents as a relatively small (<2 cm) unilateral scrotal mass in neonates or infants. Bilateral JGCT of the testes presenting as large intraabdominal masses in the neonate is very rare. Utilizing preoperative MRI findings, we report a rare case of bilateral JGCT of the testes presenting as large multiseptated abdominal masses originating from undescended intraabdominal testes in a neonate.
