[Pneumopericardium caused by gastropericardial fistula].

This is the case of a 56-year-old male who presented at our Emergency Room complaining of severe epigastric pain that radiated towards the left shoulder and neck. Pneumopericardium was diagnosed with plain chest X-rays, which indicated a gastropericardial fistula. A contrast X-ray film was taken using a water-soluble contrast. A full gastrectomy was performed with esophagojejunostomy reconstruction and pericardial drainage, which resulted in a favourable patient outcome.
