Omental torsion is a very rare cause of acute abdomen. Its primary diagnostic modality is CT. The whirl sign visible in CT images is pathognomonic. The whirl sign is not present in all cases. When no whirl sign is seen, omental torsion is rather difficult to be differantieted radiologically from omental infarct and epiploic appendicitis. The diagnosis of these three entites is clinically important due to their different treatments. We present in this paper an omental torsion case where whirl sign was not present and diagnosis was made by other suggestive CT image findings.
