| A rare non-syndromic esophageal malformation characterized by intrinsic narrowing of the esophagus, caused by congenital malformation of esophageal wall architecture present at birth. Patients manifest dysphagia and progressive vomiting. Esophageal food impaction, failure to thrive or respiratory distress can be present. Symptoms are often attributed to colic or reflux, thus diagnosis is often difficult. |
