title: Primary CT diagnosis of gastrointestinal masses.
abstract: Four cases of gastrointestinal masses (3 tumorous and 1 inflammatory) diagnosed primarily by CT, are presented. It is stressed that the radiologist should be familiar with the CT appearance of these conditions. It is recommended that in most cases barium studies and endoscopy should follow. Case 4 is unique because it represents the rare possibility of CT diagnosis of a tumor of the bowel where barium studies and endoscopy may have failed.
