ct

Unusual laminatted, hyperdense faecoliths/omas in the descending colon with inflammation/thickening in the colonic wall extending into the adjacent fat without signs of diverticular disease.

Case Discussion

Inspissated faecal materal can calcify (usually in diverticula or the appendix) and form large solid masses in the colonic lumen that can rarely lead to mural infammation and even perforation due to pressure/ischaemic effects
