Epiploic appendagitis and omental infarction are a result of torsion or vascular occlusion. Surgery or pancreatitis are conditions that can have a traumatic and ischemic effect on fatty tissue. The imaging appearances may raise concerns for recurrent malignancy, but percutaneous biopsy and di-agnostic follow-up assist in the accurate diagnosis of omental infarction. Herein we describe a case of encapsulated omental necrosis temporally related to gastric surgery. Preoperative CT and MRI findings showed the characteristics of encapsulated, postcontrast nonviable tumefaction in the epi-gastrium without clear imaging features of malignancy. Due to the size of the lesion and the pa-tient’s primary disease, tumor recurrence could not be completely ruled out, and the patient under-went surgery. Histopathological analysis confirmed the diagnosis of steatonecrosis of the omentum. © 2021 by the authors.
