case_images: CT revealed thickening of the walls of the right colon and transverse colon, with extensive calcification of the draining vessels and enlarged mesenteric lymph nodes (Figure 1). Colonoscopy showed that the right and transverse colonic mucosa was rough with dark copper-colored pigmented classes, vascular texture was lost, scattered capillary dilatation was observed, and the intestinal wall was stiff and rigid. In the ileocecal region, the mucosa was rough, dark copper-pigmented classes, the vascular texture was lost, scattered capillary dilatation was observed, and the intestinal wall was stiff and rigid (Figure 1).

case_images: The postoperative pathological findings suggested chronic inflammation of the intestinal mucosa with focal degeneration, thickening of the submucosal layer, extensive hyaline lesions of the submucosal and intramuscular vessels, calcification in focal areas, and enlargement of the lumen of some vessels with wall thickening, hyaline lesions, and calcification (Figure 3).
