Takayasu's arteritis-associated aneurysm formation without steno-occlusive lesions.

The authors report a case of a 20-year-old woman with Takayasu's arteritis (TA) presenting with recurrent erythema nodosum-like lesions, elevated acute-phase proteins and aortographic findings of multiple aneurysmal dilatations of the aorta without the coexistence of steno-occlusive lesions. This finding indicates that aneurysms could be an early manifestation of TA and not necessarily a change secondary to stenotic lesions.
