View larger version (162K): [in a new window]   Fig. 1A. —53-year-old man with phlebosclerotic colitis. On abdominal radiograph, multiple tortuous threadlike calcifications are seen throughout ascending colon and in proximal transverse colon. Calcification can be seen along mesenteric veins draining ileocecal region (arrow). Note dilatation of small-bowel loops and no gaseous distention of colon, diagnostic for small-bowel obstruction.

Axial CT images confirm presence of numerous serpiginous calcifications (arrowheads, B and C) within right colon and in adjacent mesentery. Although CT was performed after IV contrast administration, density of calcification in mesenteric veins is obvious. Mural thickening (arrow, B) is especially marked at mesenteric attachment in ascending colon with increased adjacent hazy density suggesting mesenteric vascular congestion. Obstruction of small bowel distally due to swelling of ileocecal valve from venous congestion results in dilatation of small-bowel loops.

Selective superior mesenteric digital subtraction angiogram obtained in arterial phase shows tortuosity of vasa recta (arrowheads) and marginal arteries (arrow) of right colon. This finding was subtle.

View larger version (178K): [in a new window]   Fig. 1F. —53-year-old man with phlebosclerotic colitis. Photomicrograph shows extensive submucosal fibrosis with thickened sclerosed veins (arrowheads), some of which show extensive calcification (arrows). (H and E, x10)

View larger version (35K): [in a new window]   Fig. 1E. —53-year-old man with phlebosclerotic colitis. Radiograph of right hemicolectomy specimen shows threadlike calcifications within thickened cecum and ascending colon. Arrowhead marks the terminal ileum and arrow indicates appendix.
