Note: This is a series of images of CT scan in the diagnosis, staging and therapeutic follow-up of colorectal cancers, which I prepared for a talk that I had to give to general practitioners. By ‘prepared’ I mean I had selected representative images and annotated them to show the abnormality to laymen. So this series is not going to be exhaustively informative or educative. I would suggest places like this and this for more information on colorectal cancers for health professionals and patients who stumble in here from search engines.

Caecum & Ascending Colon

Coronal curved MPR image showing a circumferential ‘apple core‘ mass involving the Caecum and proximal Ascending Colon (black arrow). The ileo-caecal junction is involved with some wall thickening in a short segment of the terminal ileum. There was no obstructive dilatation of the proximal small bowel.

Sagittal MPR image shows the same mass (yellow arrow). Both images show iodinated oral contrast in the small bowel, contrast enema in the large bowel and intravenous contrast enhancement of the abdominal organs and blood vessels. There is some oedema in the pericaecal and pericolic fat.

For further information on colorectal cancers:
