The normal appearance of the greater omentum on CT studies is a band of fatty tissue containing vessels that lies anterior to the transverse colon. Omental infarction represents an interruption of the omental arterial supply. The CT findings of omental infarction are a heterogeneous fatty mass located between the anterior abdominal wall and the colon. Typically, omental infarction occurs in the right abdomen, as in the above case, although in patients with prior abdominal surgery the location is variable. Associated peri colonic inflammatory changes may be seen.
