Omental infarction

Abstract

Omental infarction is an inflammatory, self-limiting, benign and infrequent process of the omentum major, resulting from vascular involvement. We present the case of a 34-year-old woman who went to the Emergency Room with lancinating abdominal pain, located in the mesogastrium, with irradiation to the lower left quadrant. On physical examination of the abdomen, decreased hydro-aerial noises, pain on palpation on the left flank and left iliac fossa, left lumbar percussion fist (+) are heard. The ultrasound was not contributory and the tomography revealed, in the left iliac fossa, an image of fat density of 30 mm x 15 mm with hyperdense halo, adjacent to the anterior edge of the descending colon in relation to left omental infarction. The importance of diagnostic presumption and the decision between conservative or surgical treatment is highlighted.
