Acute appendicitis in Amyand’s hernia: ultrasound findings and histopathology correlation. A case report

Abstract

Abstract Amyand’s hernia is an uncommon form of inguinal hernia. It represents <1% of all hernias and its complication with appendicitis is still rarer with 0.1–0.13% being reported. A 78-year-old woman was taken to the emergency room with pain in the right groin. The patient was assessed by ultrasound with the clinical suspicion of an inguinal hernia. We present the ultrasonographic features of appendicitis within an inguinal hernia sac. A tubular image that terminated in a blind-ended tip in the longitudinal plane and a target image on the cross-sectional plane were consistent with the sonographically demonstrated appendix. The diagnosis of Amyand’s hernia is difficult in the clinical setting. The patient is frequently referred to surgery with the diagnosis of an incarcerated hernia. Ultrasound is a good imaging modality that detects and characterizes this uncommon condition.
