Vascular lesions of Case 2. A-C: Enhanced computed tomography showed stenosis of systemic arteries (arrows). The diameters of the arteries are approximately half of normal (normal diameters: thoracic aorta, 16 mm; abdominal aorta, 9 mm; femoral artery, 6 mm). D: Angiography showed vascular irregularities in the bilateral subclavian veins (arrows).

Enhanced computed tomography showed stenosis of the thoracic and abdominal aorta and bilateral femoral arteries (Fig. 2A-C). Angiography revealed vascular irregularities in the bilateral subclavian veins (Fig. 2D), while magnetic resonance imaging of the head revealed no intracranial vascular abnormalities.
