Background. An exclusively breast-fed 8-week-old boy presented with irritability and non-bilious projectile vomiting. He was referred to our Medical Imaging Department to eliminate pyloric stenosis.¶Patient and methods. A diagnosis of colitis was strongly suggested by ultrasound. A more detailed history revealed that the patient also had episodes of colicky pain and bloody stools. An infectious colitis was subsequently excluded and rectal biopsy supported the diagnosis of allergic proctocolitis.¶Results. The infant responded well to the withdrawal of cow's milk and dairy products from the maternal diet.¶Conclusion. Allergic proctocolitis should be included in the differential diagnosis of infants presenting with vomiting and/or bloody stools.
