title: Radiological diagnosis of primary greater omental mass lesions.
abstract: Gastrocolic separation may be due to many causes including greater omental masses. This feature was noted in two patients with sarcomatous lesions and one with a haematoma of the greater omentum. This feature was not obvious in a fourth patient, with an omental tuberculous abscess who had had a partial gastrectomy. However, angiographic features in all patients were pathognomonic of an omental mass, but not necessarily of the cause of the mass.
