摘要：Omental torsion is a rare cause of acute surgical abdomen. It is caused by twisting of omentum along its long axis ending up in vascular compromise. In computed tomography presence of concentric streaks in the omental fat which is termed as whirl sign is characteristic for torsion, although it can not be visualised if the rotation axis is not perpendicular to the examination plane. We present the tomography findings of a 71 year-old male patient with surgically correlated omental torsion in the right lower quadrant hernia sac. With this case we define mushroom sign to describe the omental torsion with internal hyperdense streaks around the vascular pedincle in the hernia sac.
