Chronic Appendicitis Simulating Müllerian Malformation in Children: Case Report - Revista Brasileira de Ginecologia e Obstetrícia

Chronic appendicitis might simulate several diseases, making clinical management difficult. We report the case of a 9-year-old girl with an abdominal pain for 13 months. Ultrasound and tomography showed an expansive mass in the lower abdomen. It was extremely difficult to establish the diagnosis because the symptoms, laboratory results and images were inconclusive. The definitive diagnosis occurred only after laparotomy. We discuss in the present article several differential diagnoses for chronic appendicitis, mainly gynecological malformations, endometriosis, neoplasias and pseudotumors.
