A rare case of right and left pulmonary artery dissections on 64-slice multidetector computed tomography.

Pulmonary artery dissection is a rare but life-threatening disease, which has mainly been diagnosed at postmortem examination rather than in living patients. Herein we report an unusual case of pulmonary artery dissection involving the right and left pulmonary arteries with Eisenmenger syndrome confirmed by multidetector computed tomography (CT) and echocardiography in a living patient. The CT findings of our case are presented, and the utility of multidetector CT in the evaluation of pulmonary artery dissection is discussed.
