Radiological diagnosis of primary greater omental mass lesions.
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.
