A computed tomography (CT) scan of the entire abdomen revealed a well-defined, lobulated heterogeneously enhanced mass 17x15x7 cm in dimension in the abdominal cavity (Fig. 1).
(A) Coronal computed tomography showing a twisted omentum. These findings are consistent with the operative findings (white arrows). (B) An intra-operative photograph shows the omental mass connected to a twisted vascular pedicle (black arrows).

The coronal CT image showed a whirling pattern of fatty streaks within the omentum (Fig. 2A). The mass was twisted 1.5 rotations clockwise around the stalk (Fig. 2B).
