Introduction: Endometriosis is a rare cause of intussusceptions in adults. Although intestinal endometriosis sometimes arises as a consequence of direct involvement of the pelvic organs with endometrial tissue, there is no report that this type of endometriosis causes ileocecal intussusception.
Case presentation: Computed tomography assessment of a 40-year-old woman who presented with abdominal pain revealed ileocecal intussusceptions. The patient was managed by endoscopic reduction followed by laparoscopic resection. Adhesion between the right uterine adnexa and caecum was identified during surgery; therefore, combined resection of the uterine adnexa and ileocecum was performed. Pathological findings revealed that endometriosis, arising from the uterine tube and directly involving the cecal wall, had caused the intussusceptions.
Conclusion: Although rare, endometriosis should be considered as part of a differential diagnosis of intussusception in adult women who present with abdominal pain. A preoperative diagnosis is sometimes difficult, therefore, surgical resection could be a reasonable strategy to achieve a precise diagnosis.
