Primary and secondary omental infarction: A 5-year experience in a tertiary care hospital

Postsurgical fat necrosis is a frequent finding in abdominal cross-sectional imaging. 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 diagnostic 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 epigastrium without clear imaging features of malignancy. Due to the size of the lesion and the patient’s primary disease, tumor recurrence could not be completely ruled out, and the patient underwent surgery. Histopathological analysis confirmed the diagnosis of steatonecrosis of the omentum.

Fat in abdomen has diverse distribution and function. Insult to fat due to several causes can result in infarction or necrosis and present as acute abdomen clinically. Intra-abdominal focal fat infarction is one such condition that comprises of epiploic appendagitis, perigastric appendagitis, omental infarction, and torsion of fatty appendage of falciform ligament that have characteristic imaging features. Secondary causes of fat necrosis include pancreatitis or trauma related. Metabolic or responsive fat changes, like hypertrophy and dystrophy, can be diagnosed on imaging especially on computed tomography. Mesentric fat stranding including the mesentric panniculitis spectrum poses diagnostic dilemma and the causes and imaging role are covered in this review. Some infections and neoplasms that preferably affect abdominal fat compartments may mimic benign conditions, although some have specific patterns of involvement.

Omental infarction is a rare but a sinister cause of acute abdomen. Preoperative diagnosis is challenging due to its rare nature. It poses nonspecific abdominal signs that can be easily mistaken with other more common intra-abdominal pathologies. We report a case of a 37-year-old male patient presented with right lower quadrant abdominal pain with an elevation of inflammatory markers. His cross-sectional imaging did not a reveal specific diagnosis; therefore, a diagnostic laparoscopy was performed which revealed a non-inflamed appendix and an inflammatory mass formed by the ischemic omentum attached to the ascending colon. Diagnostic laparoscopy and subsequent laparotomy revealed spontaneous omental infarction. The histology of the resected specimen was in keeping with the omental necrosis. This case reflects the importance of considering omental infarction in patients presenting with abdominal pain and raised inflammatory markers. He made an uneventful recovery following surgery.
