[Diagnostic imaging of idiopathic segmental infarct of the greater omentum. Diagnostic and physiopathologic considerations].
Primary infarction of the greater omentum is a rare cause of acute abdominal syndrome. Rate of occurrence may nevertheless be underestimated. We report a series of six cases observed over a 30-month period with US and CT imaging. We assessed early signs and their course. CT-scans depicted fatty oval-shaped masses below the right anterior or anterolateral parietal wall, associated with a thickening of the anterior parietal peritoneum, explaining symptom pathogenesis. Torsion can be identified, but has no specific impact on prognosis. Follow-up CT scan may evidence spontaneous, but sometimes slow, resolution.
