Ménétrier's disease evaluated serially by abdominal ultrasonography

Area of Science:

• Pediatric Gastroenterology
• Medical Imaging
• Cell Biology

Background:

• Ménétrier's disease is a rare condition characterized by gastric mucosal hypertrophy.
• It often presents with abdominal pain, vomiting, and hypoalbuminemia.
• Diagnosis can be challenging, requiring a combination of imaging and biopsy.

Observation:

• A 3-year-old boy with Ménétrier's disease presented with significant anasarca and hypoproteinemia.
• Gastric wall thickening was observed via sonography, which resolved over time.
• Electron microscopy revealed widened gastric tight junctions (>10 nm).

Findings:

• Ultrasonography effectively diagnosed Ménétrier's disease and monitored its progression.
• Persistent widening of gastric tight junctions was identified as a key pathological feature.
• Supportive treatment led to a full recovery within 3 weeks.

Implications:

• Ultrasonography is a valuable, non-invasive tool for diagnosing and managing Ménétrier's disease in children.
• Understanding gastric tight junction dynamics offers insights into protein loss in this condition.
• Early diagnosis and supportive care are crucial for favorable outcomes in pediatric Ménétrier's disease.
