Fig. 2 72-year-old afebrile woman with epiploic appendagitis who presented
with acute left lower quadrant pain and laboratory values within normal
ranges. Axial contrast-enhanced CT scan at level of junction of descending and
sigmoid colon shows oval paracolonic fatty mass with hyperattenuating rim
(arrow) that is characteristic of epiploic appendagitis, despite
presence of diverticula (arrowheads). In addition, this patient's
clinical presentation is not typical of someone with diverticulitis. In a
patient with no prior surgery, location and appearance would also preclude
segmental omental infarction.
