Insights
Pediatric omental infarction, a rare cause of acute abdomen, can be diagnosed pre-operatively. Computed tomography (CT) findings are suggestive, while histopathology often reveals vasculitis.
Area of Science:
- Pediatric Surgery
- Radiology
- Pathology
Background:
- Omental infarction is an uncommon condition in children, often presenting as acute abdomen.
- It can mimic other surgical emergencies like appendicitis and cholecystitis.
Purpose of the Study:
- To review clinical and imaging findings of pediatric omental infarction.
- To identify features aiding pre-operative diagnosis.
Main Methods:
- Retrospective review of six pediatric cases with histopathologically confirmed omental infarction.
- Analysis of clinical presentation, ultrasonography, and computed tomography (CT) findings.
Main Results:
- CT demonstrated suggestive findings aiding pre-operative diagnosis of omental infarction.
- Ultrasonography findings were less specific.
- Histopathology revealed vasculitis in all reviewed cases.
Conclusions:
- Clinical and imaging features can facilitate pre-operative diagnosis of pediatric omental infarction.
- Vasculitis is a potential underlying pathology for this condition.
Introduction:
Omental infarction is a rare occurrence in the paediatric population. It often presents as an acute abdomen that can mimic acute appendicitis and cholecystitis.
Methods:
Six cases of omental infarction in children, proven on histopathology, were retrospectively reviewed for their clinical presentation and imaging findings on ultrasonography and computed tomography.
Results:
These cases revealed clinical and imaging findings on computed tomography that were suggestive and helpful in the pre-operative diagnosis of omental infarction. Findings on ultrasonography were less specific. Histopathological specimens revealed findings of vasculitis in all cases.
Conclusion:
There are clinical and imaging features that will help in the pre-operative diagnosis of this uncommon condition. We also postulate vasculitis as a possible underlying pathology for omental infarction.
