title: Initial isolated Takayasu's arteritis of the right pulmonary artery: MR appearance.
abstract: Takayasu's arteritis involves the pulmonary artery tree in more than 50% of the cases. Initial isolated involvement of the pulmonary artery by Takayasu's arteritis, however, is very rare. We report the case of a 34-year-old white woman who presented a clinical and radiographic pattern that mimicked an acute pulmonary embolism with pulmonary infarction. Pulmonary angiography showed stenosis lesions and occlusion of the right pulmonary artery tree. Magnetic resonance imaging demonstrated thickening of the pulmonary artery wall leading to the correct diagnosis.
