Primary tumours of the greater omentum

Abstract

Primary tumours of the greater omentum are very rare. Ultrasound allows the detection and characterization of such lesions, but determination of their precise anatomical location is usually difficult by US. Computed tomography determines the omental origin of the tumour. Thus, when US reveals an abdominal tumour of unknown origin, the possibility of an omental tumour, although rare, must be kept in mind and CT should be performed.
