Primary omentitis as a cause of acute abdomen

A 5-year-old boy admitted with localized lower abdominal pain and tenderness simulating acute appendicitis underwent surgery, and primary omentitis without appendicitis or other cause of an acute abdomen was diagnosed. The absence of other concomitant signs and symptoms of acute abdomen was remarkable. This is the first case of primary omentitis as a cause of acute abdomen in the English-language literature.
