Colon CT Appearances
Colon Cancer CT Findings
- Discrete soft-tissue mass that narrows the colonic lumen
- Large masses may undergo central necrosis and appear as a soft-tissue mass with central low attenuation or rarely air attenuation
- Focal colonic wall thickening and luminal narrowing
- Virtual colonoscopy with air distended colon is ideal for lesion detection
- Without proper prep it is easy to overcall or undercall colon cancer on CT
