“…These pos sibilities were easily dismissed in our patient by clinical findings and by the macro-and microscopic aspects of the aneurysms. Idiopathic (Takayashu's) aortitis, another relatively frequent cause of aneurysms in children or young adults [8,17], sometimes of the saccular type [7,9,20], was likewise not considered to be operative in our patient. Indeed, idiopathic (Takayashu's) aortitis manifests itself by hypertension, cardiomegaly and frequently absence or weakness of the radial pulses [5,14,21]; the aneurysms most often consist in large fusiform-type swellings of both thoracic and abdominal aorta with areas showing obstructive lesions due to proliferative changes [14,21]; microscopically, there is a panarteritis affecting localized areas of the aorta.…”
