Insights
Eosinophilic gastroenteritis (EG) in infants can mimic idiopathic hypertrophic pyloric stenosis (IHPS). Ultrasound (US) of the antropyloric region aids in distinguishing these conditions, crucial for appropriate treatment.
Area of Science:
- Pediatric Gastroenterology
- Diagnostic Imaging
Background:
- Eosinophilic gastroenteritis (EG) is a rare condition.
- It can present with symptoms similar to idiopathic hypertrophic pyloric stenosis (IHPS).
Observation:
- Two infants with EG were studied.
- Clinical symptoms and ultrasound (US) findings of EG can mimic IHPS.
- US of the antropyloric region using a high-frequency linear transducer was performed.
Findings:
- US examination can differentiate EG from IHPS.
- This distinction is critical due to differing treatment strategies.
Implications:
- EG should be included in the differential diagnosis for suspected IHPS.
- Consider EG in cases of IHPS with failed pyloromyotomy.
Abstract:
We report two infants with eosinophilic gastroenteritis (EG). This rare disease can mimic the clinical symptoms and US appearance of idiopathic hypertrophic pyloric stenosis (IHPS). US examination of the antropyloric region with a high-frequency linear transducer can assist in the differentiation of EG from IHPS, which is important because the therapeutic approaches are completely different. Eosinophilic gastroenteritis should be considered in the differential diagnosis of IHPS, especially when there has been an ineffective pyloromyotomy.
