INITIAL ISOLATED TAKAYASUS-ARTERITIS OF THE RIGHT PULMONARY-ARTERY - MR APPEARANCE

Takayasu's arteritis involves the pulmonary artery tree in more than 5 0 % 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 p attern that mimicked an acute pulmonary embolism with pulmonary infarc tion. Pulmonary angiography showed stenosis lesions and occlusion of t he right pulmonary artery tree. Magnetic resonance imaging demonstrate d thickening of the pulmonary artery wall leading to the correct diagn osis.
