Summary
This study reports three cases of trichobezoar, a rare stomach condition. Ultrasound revealed characteristic findings, aiding in diagnosis when clinical suspicion was low.
Area of Science:
- Gastroenterology
- Medical Imaging
- Pediatric Surgery
Background:
- Trichobezoars are rare gastric foreign bodies, often presenting with non-specific symptoms.
- Clinical diagnosis of trichobezoar can be challenging, especially in pediatric patients.
- Epigastric masses require thorough investigation to determine the underlying cause.
Observation:
- Three patients (two children, one adult) presented with epigastric masses.
- Initial clinical suspicion for trichobezoar was low in all cases.
- Sonography was performed for diagnostic evaluation of the epigastric masses.
Findings:
- Ultrasound revealed a hyperechoic curvilinear dense strip with acoustic shadowing.
- These characteristic sonographic findings were consistent across all three cases.
- In vitro ultrasound of surgical specimens confirmed the trichobezoar as the source of the findings.
Implications:
- Sonography can be a valuable non-invasive tool for diagnosing trichobezoars.
- Characteristic ultrasound findings can aid in early diagnosis, even without high clinical suspicion.
- Prompt diagnosis and surgical intervention are crucial for managing trichobezoar complications.
