case_images: (A) NMR transverse axial view: the red arrow indicates a soft tissue mass located in the left mid-abdomen, closely related to the bowel, approximately 6.4*4.7cm, with multiple internal gas signals; (B) Coronal view of MRI; (C) Barium enema X - ray: the red arrow points to a right-to-left image of a smaller intestinal tube about 190mm long; (D) Endoscopy: the black arrow points to an open-like structure, and the distal segment's stenosis was obvious; (E, F) Pathology: chronic inflammation of mucosal tissue covered with squamous epithelium and gastric columnar epithelium). Coloration HE, magnification x100.

case_images: Pathological diagnosis showed chronic inflammation of mucosal tissue covered with squamous epithelium and gastric columnar epithelium ( Figures 2A-F ).
case_images: Specimens seen and resected during surgery [(A, B) proximal splenic flexural mass at the back of the transverse colon, approximately 8.0 cm by 9.0 cm, inflammatory edema of the surrounding tissues, the root of the mass is connected to the middle section of the transverse colon, and the root of the mass is exposed with nourishing blood vessels emanating from the ligament of Treitz; (C) The specimen showed intestinal mucosal tissue in the mass. The black arrow indicates a duplicate deformity that separates from the normal transverse colon and communicates with the intestinal lumen)].

case_images: The root of the mass was exposed, revealing nourishing blood vessels emanating from the ligament of Treitz, and a dissected specimen showed the presence of intestinal mucosal tissue in the mass ( Figures 3A-C ). we removed the duplicate colon and extended it 2cm into the original transverse colon, and performed a colon-colon anastomosis with a stapler.
case_images: Pathology report (A) and (B) can be seen in the intrinsic muscular wall, covered with squamous epithelium, gastric mucosa, and large intestine mucosa). coloration HE, magnification x200.

case_images: Postoperative pathology ( Figures 4A, B ) (transverse colon) revealed a microscopic organ-like structure visible to the intrinsic muscle wall, which was covered with squamous epithelium, gastric mucosa, and large intestine mucosa.
