This paper reports a case study of a 36-year-old woman with abdominal pain in whom appendiceal intussusception was suspected to reflect a cecal tumor based on laparoscopic findings. The patient underwent laparoscopic right hemicolectomy, and histopathology instead showed an intussuscepted appendix caused by massive endometriosis involving the colon, ileum, and appendix. The authors emphasize that appendiceal intussusception and appendiceal endometriosis can mimic other intraabdominal pathologies, which is a diagnostic limitation inherent to presentation-based interpretation. This paper is centrally about endometriosis — it describes massive intestinal/appendiceal endometriosis presenting as appendiceal intussusception that mimicked a tumor.

Abstract

Appendiceal intussusception is a rare clinical entity that, in women of reproductive age, may be caused by endometriosis. We report a case of a 36-year-old woman presenting with abdominal pain. The patient underwent laparoscopic surgery, during which a suspicion of a cecal tumor was raised. A laparoscopic right hemicolectomy was performed. The patohistological exam showed an intussuscepted appendix, and the cause of the intussusception was massive endometriosis involving the colon, ileum, and appendix. It is important not to mistake appendiceal intussusception and appendiceal endometriosis with other intraabdominal pathologies whose symptoms they can mimic
