Boerhaave's syndrome with rupture of the right wall of the esophagus after oral administration of sulfate solution.

A 63-year-old male took magnesium sulfate for bowel cleansing and subsequently developed severe nausea and vomiting. He then suffered from acute epigastric pain and compression pain in the right chest, with dyspnea, chest tightness and palpitation. Physical examination revealed subcutaneous emphysema in the neck, with crepitus and diminished breathing sounds on the right side of the chest. A thoracic computed tomography (CT) scan showed mediastinal emphysema, right-sided pleural effusion and pneumothorax.
