Abstract
|
|
|
|
Pulmonary artery dissection is rarer than other intraluminal diseases of pulmonary artery such as pulmonary thromboembolism or pulmonary artery sarcoma. We report two cases of pulmonary artery dissection mimicking pulmonary artery sarcoma. Computed tomography (CT) showed no enhancement of intrapulmonary arterial lesion or expansion of involved pulmonary artery. Magnetic resonance imaging (MRI) showed low-signal intensity intimal flap on T1- and T2-weighted images. There was no fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET)-CT. In this case report, we describe the imaging features of pulmonary artery dissection on CT, MRI, and PET-CT.
