Typically infiltrates the gastric wall causing limited distensibility w/ mucosal irregularity and/or intraluminal mass

Very scirrhous tumors (firm and likely to constrict/obstruct structures they involve)

Fixed narrowing with absence of peristalsis through the involved segment.

• When antrum is involved, GOO may result. 

Often reach a large size w/ foci of necrosis

Rarely cause gastric outlet obstruction

MC organ of origin

Circumferential gastric mass of ST attenuation

Results in massive nodular thickening of folds but normal distensibility

Some tumors like breast and melanoma have a propensity for gastric metastases

Can cause nodular intramural masses with/without ulceration and with/without distensibility

• Breastr has propensity to cause thick folds w/ limited distensibility
