Aberrant pancreatic tissue causing gastric ulcer and pyloric obstruction.

A 5-year-old boy was admitted for recurrent episodies of upper abdominal pain and vomiting for the past two years associated with loss of weight. The vomiting was non projectile, occurred shortly after meals, and was never blood or bile stained. On examination there was visible gastric peristalsis and mildly enlarged liver. The cardiovascular system examination revealed a continuous murmur in the pulmonary area suggestive of patent ductus arteriosus.
