title: Ascending aortic dissecting aneurysm with isolated right pulmonary arterial medial intramural hematoma.
abstract: On rare occasions, acute aortic dissection may cause pulmonary artery obstruction when there is aortic rupture with hemorrhage into the common adventitia of the aorta and pulmonary artery. We report an extremely unusual case of an ascending aortic dissecting aneurysm associated with an isolated medial intramural hematoma in the right pulmonary artery in an 86-year-old woman with clinical manifestations mimicking pulmonary embolism. We believe that this rare pulmonary arterial complication of aortic dissection without involvement of the common adventitia has not been previously described.
