Pyloric atresia with epidermolysis bullosa: fetal MRI diagnosis with postnatal correlation.

Pyloric atresia is an uncommon congenital gastric outlet obstruction, accounting for only 1% of gastrointestinal atresias. Up to 55% of cases have associated anomalies, the most common of which is epidermolysis bullosa. Fetal MRI findings of the epidermolysis bullosa-pyloric atresia association have not been previously reported. We present a case of this association diagnosed by prenatal MRI with corroborative postnatal imaging and surgical findings.
