This case report describes a 33-year-old woman presenting with classic clinical and radiological signs of acute appendicitis. The patient underwent laparoscopic appendicectomy, during which the appendix appeared normal but histological examination revealed endometriosis within the meso-appendix. The authors note that while endometriosis of the appendix or its association with intussusception has been previously reported, this specific presentation mimicking appendicitis had not been documented prior to this case. This paper is centrally about endometriosis — specifically describing an unusual extra-pelvic manifestation in the meso-appendix that can mimic acute surgical emergencies.

Abstract

Although appendicitis is largely a clinical diagnosis, on occasions diagnostic modalities may be needed to aid with the diagnosis. Despite the use of adjuncts and exploratory surgery, the diagnosis may not be clear until a histological diagnosis is achieved. Endometriosis of the appendix mimicking appendicitis is one of these diagnoses described in several case reports. Endometriosis of the meso-appendix has been described in association with intussusception of the appendix in several case reports. However, to our knowledge, endometriosis of the meso-appendix mimicking appendicitis has not been reported to date. We present the case of a 33-year-old woman with classic clinical signs and symptoms of appendicitis endorsed on computed tomography imaging. The patient underwent a laparoscopic appendicectomy with the postoperative histology demonstrating a normal appendix with endometriosis of the meso-appendix.
