Introduction.

The intussusception of the appendix corresponds to its invagination in the cecum. There are several causes, endometriosis being rarely reported. Although the diagnosis must be suspected clinically, its cause is generally only determined intraoperatively, where oncological causes that require extensive resection must be taken into account.

Clinical case.

A 21-year-old woman who consulted due to acute generalized abdominal pain, an abdominal tomography was performed, finding an intussusception of the appendix in the cecum, striation of pericecal fat, and lymph nodes. A diagnostic laparoscopy was performed, finding almost complete intussusception of the appendix, with a neoplastic appearance. She was converted to laparotomy to perform a right hemicolectomy, with lymph node dissection and ileal to transverse anastomosis.

Discussion.

Clinical suspicion of intussusception should be confirmed by ultrasound, abdominal tomography, or barium studies. Treatment is always surgical, as in the case of our patient, who evolved adequately and remained asymptomatic after one year of follow-up.

Conclusion.

Early diagnosis of intussusception allows for less aggressive surgical treatment and decreases the risk of anastomosis leakage. The diagnosis of endometriosis should be taken into account as a possible cause. Complementary management by gynecologists should be performed.
