Omental infarction present with right upper quadrant pain, case report.

Omental infarction is a rare cause of pain and must be considered in the differential diagnosis of acute abdomen. It arises in any quadrant that contains omentum when a compromised blood supply takes place. We report a morbid obese 45-year-old male with Diabetes mellitus, dyslipidemia and coronavirus-disease-related pneumonia 2 months prior to his emergency presentation with acute epigastric and right upper quadrant pain. The patient was investigated by computed tomography (CT), and the provisional diagnosis was biliary colic from gallbladder stone. The patient's pain was severe and not compatible with biliary colic. Diagnostic laparoscopy approached and an incidental finding of omental necrotic area. Excision of the infarcted omentum in addition to cholecystectomy was done. The patient's postoperative course was uneventful, and he was discharged home after 2 days. In our case, the CT image did not discover mental changes that may help us to make a preoperative diagnosis.
