Amyand's hernia: prospective CT diagnosis.

We report two cases of Amyand's hernia, which is the development of acute appendicitis within an inguinal hernia. Both patients were clinically thought to have incarcerated inguinal hernias, but were correctly prospectively diagnosed as having Amyand's hernia on the basis of preoperative computed tomography (CT) examinations. Our cases again show the utility of CT of the acute abdomen and pelvis in revealing a previously unsuspected diagnosis and rapidly triaging patients to the appropriate management.
