Patient Data

Age: 90
Gender: Male

Patient unwell so no IV or oral contrast

Distension of the colon to the sigmoid with abrupt transition to collapsed rectum. Irregular mass in the sigmoid is probably cancer although a diverticular stricture is possible. Gross cecal dilatation with swollen irregular, gas-filled mucosa is compatible with ischemia (probably venous due to luminal distension) and free gas indicating perforation, although the site of perforation is not identified.
