Failure to Thrive: An Expanded Differential Diagnosis

Abstract

The patient is a term 6-month-old male, who presented with failure to thrive since birth. History was remarkable for suspected milk and soy protein allergy, gastroesophageal reflux, constipation, and abdominal distension that was present since birth. He was losing weight despite oral intake of over 100 kcal/kg per day. Prior workup including laboratory studies, abdominal X-ray, upper gastrointestinal series with fluoroscopy, barium enema, and abdominal ultrasound were all within normal limits. The patient's history, diagnostic evaluation, and final diagnosis are revealed. This case highlights a rare condition presenting as failure to thrive, a common problem with a wide differential diagnosis.
