The French and their hernias: prospective radiological differentiation of de Garengeot from other groin hernias.

A femoral hernia containing an appendix, known as de Garengeot hernia, is an uncommon and potentially confusing presentation. Prompt differentiation of this condition from other groin hernias in an acute setting will influence management and reduce morbidity. Computed Tomography (CT) should be performed in all suspected cases and an awareness of likely CT findings can facilitate rapid pre-operative diagnosis. Despite this, we present only the fourth published case of prospective CT diagnosis of de Garengeot hernia.
