Right hemothorax: an unusual presentation of ruptured infrarenal abdominal aortic aneurysm.

The authors describe what they believe is the first reported case of rupture of an infrarenal abdominal aortic aneurysm into the right pleural cavity. A 75-year-old woman presented simultaneously with two common causes of severe abdominal pain and hypotension: perforated duodenal ulcer and ruptured abdominal aortic aneurysm. The absence of an infrarenal retroperitoneal hematoma delayed the diagnosis of rupture of the abdominal aortic aneurysm and the terminal event was exsanguination into the right pleural cavity through an erosion in the right hemidiaphragm.
