Overview
CT
CT is currently the staging modality of choice because it can help identify the primary tumor, assess for local spread, and detect nodal involvement and distant metastases
Demonstration of lesions facilitated by negative contrast agents (water or gas):
- a polypoid mass with or without ulceration
- focal wall thickening with mucosal irregularity or focal infiltration of wall
- ulceration: gas-filled ulcer crater within mass
- infiltrating carcinoma: wall thickening and loss of normal rugal fold pattern
Calcifications are rare but when present, they are usually mucinous adenocarcinoma.[1]
