Colon CT Appearances

Cecal Carcinoma 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
• May appear as asymmetric nodular wall thickening that narrows the lumen
• May be difficult to distinguish from cecal lymphoma or occasional ischemic colitis or typhlitis
