Excerpt
The imaging findings, including sonography, of children (N = 12) with surgically proven omental infarction were reviewed.
All 12 children presented with right-sided abdominal pain, 9 localized to the right iliac fossa and 3 to the right hypochondrium. Nine children had low-grade fevers and 9 children had significant neutrophilia.
Eight children had imaging examinations, including one having sonography only, five having abdominal CT only, and two having both abdominal CT and sonography. Four patients who had had CT examinations had the correct preoperative diagnosis of omental infarction. Sonography reported features of acute appendicitis in one patient and was reportedly normal in two.
In the discussion, the authors describe the usual sonographic and CT features of omental infarction, including the “cake-like” noncompressible, hyperechoic fat at the point of tenderness seen at sonography. The authors further stress the importance of considering omental infarction, while rare, in children presenting similar to acute appendicitis. The disease entity may be more common than reported in the literature, and the treatment may be different, as conservative management may be employed in some cases of omental infarction.
