Fig. 29 — A 43-year-old female presented with acute right-sided abdominal pain. a Axial plane postcontrast abdominal CT showed ill-defined mass-like omental lesion (arrowheads) with adjacent fat stranding. Note was also made of a hyperdense dot (arrow) within the lesion. Imaging findings were suggestive of an omental infarct, and the central hyperdense dot was thought to represent a thrombosed vascular structure, although it is an atypical finding for an omental infarct. The patient developed fever and progressively increasing abdominal pain despite maximum supportive treatment and finally underwent a laparoscopic excision to rule out secondarily infected omental infarct. Pathological evaluation revealed a nonneoplastic inflammatory omental mass containing a fishbone and foreign body reaction. b Based on pathological findings, a retrospective evaluation on the coronal plane demonstrated linear hyperdensity representing the fishbone (arrows)
