The Intussusception of Appendix Due to Extrapelvic Endometriosis: A Case Report

Endometriosis is among the most frequent causes of appendiceal intussusception. However, there are limited data about this condition. Still, clinical manifestations, diagnosis, and treatment are the same in almost all cases due to accidental implantation of endometrial tissue inside the appendiceal wall. Finally, the only choice of treatment is appendectomy. Here we describe a middle-aged woman with vague pelvic pain that underwent a laparoscopic cystectomy, and during surgery, we came across a mass-like appendix. The pathology report declared that some endometrial tissue inside the appendix confirms the diagnosis of appendiceal intussusception due to endometriosis.
