[Idiopathic and torsion-induced omental infarct: case reports and a review of the literature].

: The authors review nosologic problems related to the infarction of the greater omentum on the ground of two cases (one idiopathic, the other by torsion) recently observed. Omental infarction, far from being a real diagnostic or surgical problem, is an unusual cause of acute abdomen; resection of the affected omentum is curative in 100% of cases.
