Pneumopericardium due to intrapericardial perforation of a gastric ulcer.

A 88-year-old male patient presented with fever, singultus and retrosternal pain. After 8 days of antibiotic therapy not resulting in clinical improvement, he suddenly developed a pneumopericardium. Contrast swallow and endoscopy showed intrapericardial perforation of a benign gastric ulcer. Excision of the ulcer and suturing of both the stomach and the diaphragm as well as lavage of the pericardium were done over a left thoracotomy. The patient recovered uneventfully.
