Computed tomography appearances of Amyand hernia.

Appendix-containing inguinal hernias are known as Amyand hernias. Traditionally, these hernias have been diagnosed at surgery but are increasingly diagnosed on abdominal computed tomography scans. The classification of Amyand hernias determines their subsequent surgical management; as such, it is important for the radiologist to be familiar with the appearances of the subtypes of Amyand hernias.
