Thumbprinting – a plain radiograph sign of colitis. Normal large bowel haustrations are thin projections into the lumen, however in the setting of colitis these become thickened due to oedema. When outlined by the gas-filled lumen, it can look as if someone has pressed their thumb at regular intervals along the bowel wall. The above patient had pseudomembranous colitis with thumbprinting seen in the left upper quadrant (CT shown for correlation also shows thumbprinting elsewhere in the large bowel). Other forms of colitis such as ulcerative colitis, Crohn’s disease and ischaemic colitis could cause the same appearance.
