A case of torsion of the undescended testes

Abdominal pain and vomiting are common presenting symptoms in young children, and there are a myriad of differential diagnoses ranging from benign to life‐threatening. We present the case of a 20‐month‐old boy who came to the emergency department with abdominal pain, fever, and vomiting. Initially, he was thought to have intussusception with a necrotic lead point based on clinical signs, laboratory findings, and ultrasonography, but was taken to the operating room after air enema failed to demonstrate an intussusceptum. He was ultimately diagnosed with torsion of an undescended testicle. Few cases of torsion of the undescended testes are reported in literature.
