The roentgen features of metastatic disease to the colon may be diagnostic and have been divided into 2 groups: (1) colonic involvement by extension from an extracolonic mass and (2) primarily intramural involvement.

The more common roentgen findings include narrowing of the lumen, obstruction, nodular defects, fixed transverse or radiating folds, limitation of distensibility and extensibility and incomplete collapsibility. Ulceration is absent until the late stages. Diffusely infiltrating involvement may occur and be associated with marked fibrosis, producing an appearance indistinguishable from primary scirrhous carcinoma of the colon. Metastatic hypernephromas, because of minimal desmoplastic reaction, produce large bulky cellular tumors.
