Left-sided omental infarction: A rare cause of abdominal pain, discovered by CT scan

Omental infarction in adults is a rarely occurring phenomenon, with left-sided omental infarction being even more seldom. The importance of this case report lies in raising awareness of the diagnosis omental infarction as a cause of acute abdomen among doctors who work in the emergency department, in order to prevent unnecessary surgical interventions as conservative treatment generally solves the problem. Omental infarction is the result of vascular obstruction and ends in tissue ischaemia. Because of the rich vasculature of the greater omentum, anastomoses reorganise the vascularisation, which explains the mostly benign course of omental infarction. By adding omental infarction to the list of differential diagnoses in patients who present with acute abdominal pain, future management of patients with an acute abdomen can be adjusted for the optimal approach to not overlook any surgery-requiring diagnosis as well as to prevent overtreatment.
