Torsion of an indirect hernia sac within a hydrocele causing acute scrotum: case report and review of the literature.

We report a case of acute scrotum in a 2-year-old child caused by torsion of an indirect hernia sac within a hydrocele. This is an extremely rare cause of acute scrotal swelling and pain in the pediatric population, with this case representing only the eighth instance reported in the literature. Despite the scarcity with which this diagnosis has been encountered, clinicians should include torsion of an indirect hernia sac on the differential diagnosis for acute scrotum in a child.
