Pediatric cases of Spigelian hernias are rare. Only a few reports on this condition, in combination with ipsilateral cryptorchidism and testis in the hernia sac, have been published. We report on Spigelian hernia in a 3-week-old boy containing both the ipsilateral testis, without a gubernaculum and an incarcerated loop of the small intestine. It has been suggested that the combination of Spigelian hernia and ipsilateral cryptorchidism is part of a new syndrome. We discuss whether the lack of a gubernaculum and an inguinal canal reported in other similar cases may be additional elements of this new syndrome. We present a comprehensive overview of pediatric patients with Spigelian-cryptorchidism syndrome reported in the English language literature. In 75% of male infants with Spigelian hernia, there is an associated ipsilateral cryptorchidism, and in 87% of these patients, the testis is found inside the hernia sac. Thus, the surgeon dealing with a congenital Spigelian hernia should look for an undescended testis and be prepared to find it in the hernia sac.
