Omental torsion in a guinea pig (Cavia porcellus).

An adult intact male guinea pig (Cavia porcellus) was presented with gastrointestinal stasis. Radiographic findings demonstrated a gas- and fluid-filled cecum. Treatment was initiated but the animal died shortly after presentation. Gross postmortem revealed omental torsion with vascular thrombosis and necrosis. This is the first report of omental torsion with vascular thrombosis in a domestic animal.
