case_images: Abdominal contrast-enhanced computed tomography showed a mass in the small intestine in the pelvic area and intussusception with the tumor as the lead point (Fig. 1a, b).

case_images: The operation was performed under general anesthesia in the supine position using three ports (Fig. 2).
case_images: Intraoperative findings. a Intussusception of the small intestine in the pelvic ileum (arrow). b An approximately 3-cm elastic soft mass 400 cm from the ligament of Treitz at the lead point of intussusception (arrowhead).

case_images: Intra-abdominal examination revealed intussusception of the small intestine in the pelvic ileum, with no other abnormal findings (Fig. 3a). After extracting the lesion from the body through a small laparotomy, the intussusception was removed manually, and an elastic soft mass, 3 cm in diameter, was identified at the lead point of the intussusception (Fig. 3b).
case_images: a Macroscopic imaging of the ileum showing a pedunculated tumor (x 292 x 7 x 24 mm). b Histopathological examination (HE x4) showing typical villiform projections. c Histopathological examination (HE x40) showing cells containing abundant brightly eosinophilic cytoplasm with centrally placed, slit-like serrations (arrow), and ectopic crypt formations (arrowhead).

case_images: Macroscopic inspection of the resected ileum showed a pedunculated tumor measuring 29 x 27 x 24 mm in size (Fig. 4a). In addition, a flat arrangement of eosinophilic cells and ectopic crypts were observed in some areas (Fig. 4b, c).
