Summary

Gastric trichobezoars are rare in children. This report highlights the distinctive imaging appearance of gastric trichobezoars on ultrasound and computed tomography, crucial for early diagnosis in pediatric abdominal masses.

Area of Science:

  • Pediatric Radiology
  • Gastrointestinal Imaging
  • Medical Diagnostics

Background:

  • Gastric trichobezoars are rare foreign bodies composed of ingested hair.
  • They can cause significant gastrointestinal symptoms in children.
  • Prompt diagnosis is essential for effective management.

Purpose of the Study:

  • To describe the characteristic imaging findings of gastric trichobezoars.
  • To emphasize the role of ultrasound and computed tomography in diagnosing pediatric gastric trichobezoars.
  • To improve recognition of this condition in young patients.

Main Methods:

  • Case report of two pediatric patients with gastric trichobezoars.
  • Review of imaging studies including ultrasound, computed tomography, and upper gastrointestinal contrast studies.

Related Experiment Videos

  • Correlation of imaging findings with clinical presentation.

    • Main Results:

    • Ultrasound demonstrated a well-defined, hyperechoic mass with acoustic shadowing.
    • Computed tomography revealed a heterogeneous intraluminal mass with characteristic layering.
    • Upper gastrointestinal contrast studies confirmed intraluminal filling defects.

    Conclusions:

    • Gastric trichobezoars have a distinctive appearance on common pediatric imaging modalities.
    • Sonography and computed tomography are valuable tools for identifying gastric trichobezoars in children.
    • Early recognition of these imaging features can facilitate timely intervention.
