A 4-year-old boy presented with a bulge on the right side of the chest. The parents had noticed the swelling for the first time 3 weeks before (Panel A). At the age of 6 months, a diagnostic work-up for focal seizures had revealed tuberous sclerosis (Bourneville's disease) with left frontal and paraventricular cortical tubers, a renal angiomyolipoma on the right, multiple hypomelanotic macules of the skin (Panel B), and rhabdomyomas of the heart in the left ventricle (Panel C).
Physical exam showed a 5 x 5 cm subclavian and axillary mass with palpable pulsation and audible flow murmur. Peripheral pulses and blood pressure in all extremities were inconspicuous. Selective angiography confirmed the diagnosis of a subclavian artery aneurysm (Panel D). Magnetic resonance angiography was performed with a 1.5-T scanner to rule out additional aneurysms (Panel E), picturing also the large rhabdomyomas in the left ventricle (Panel F).
Surgically treatment with resection of the aneurysm and interposition of saphenous vein graft was performed. Histological examination confirmed a true aneurysm.
Aneurysms of the great arteries can occur in patients with tuberous sclerosis. This rare association has to be remembered in the management of patients with tuberous sclerosis at any age.
