Abdominal vascular computed tomography (CT) angiography revealed atherosclerotic changes in the lower abdominal aorta, bilateral common iliac arteries, and internal iliac arteries, with corresponding mild stenosis and extensive calcification of the venous network in the ascending and transverse parts of the colon (arrow).

C-reactive protein level of 194.8 mg/L. Computed tomography (CT) angiography revealed atherosclerotic changes with mild luminal stenosis in the lower segment of the abdominal aorta, left and right common iliac arteries, and left and right internal iliac arteries (Figure 1).
Abdominal CT and enhanced CT revealed extensive calcification of the venous network in the ascending colon and transverse colon, with edema and thickening of the intestinal wall and small intestinal obstruction.

The bowel wall was edematous and thickened, and small bowel obstruction was observed (Figure 2).
Macroscopically, the colonic mucosa appeared dark purple, and the colonic wall was significantly thickened (arrow).

IMP was confirmed by postoperative pathological findings (Figures 3, 4).
(A) Histological microscopy showing epithelial detachment in the lamina propria of the intestinal mucosa, local vascular slide, interstitial collagenization, and mucosal muscle atrophy in the area. The vascular wall in the submucosa was extensively thickened and narrowed with slide, local calcification, and interstitial collagenization (hematoxylin and eosin staining). (B) Arrow: Extensive stenosis, occlusion with degeneration, calcification, and ossification of thick-walled vessels on the serosal side (hematoxylin and eosin staining).
