Figure 1 Abdominal radiograph. It showing multiple distended loops of small bowel with fluids and multiple air pockets (A) and computed tomography showing multiple gas-filled cysts, a streaky collection of air in the bowel wall, and an intussusception of the colon (B).

Figure 2 Intraoperative findings showed intussusception of the ascending colon with palpable soft polypoid masses.

Figure 3 Intraoperative colonoscopy showed numerous soft polypoid masses with normal overlying mucosa located between the ascending colon and middle part of transverse colon.

Figure 4 The resected specimen revealed polypoid lesions with normal mucosa and cystic structures (A), submucosal cysts had a spongy consistency (B).

Figure 5 Histopathological examination revealed cystic air-filled spaces within the submucosa, which were partially lined by clusters of foreign-body macrophages (arrow heads) (hematoxylin-eosin stain; A: × 40, B: × 400).
