Duplication cyst of the stomach presenting as hemoptysis.

We report a rare case of a 2-year-old boy with a gastric duplication cyst located in the stomach, presenting with vague abdominal pain, recurrent cough, hemoptysis and a lesion in the left lower lobe of the lung reported as a sequestration. The duplication cyst was attached to the diaphragm and lungs by a narrow tract. The cyst was excised. Subsequent scans of the chest showed regression of the lung lesion. We believe this to be the first case in the literature where the hemoptysis was cured and the pulmonary lesion regressed completely after excision of the duplication cyst of the stomach alone. Pulmonary resection was thus avoided.
