Atypical Takayasu arteritis with solitary stenosis in the short segment of right axillary artery.

Takayasu arteritis is a rare, idiopathic, and chronic inflammatory large vessel vasculitis, involving mainly the aorta and its major branches. Takayasu arteritis predominantly affects women. The clinical presentation is characterized by an acute phase with constitutional symptoms, followed by a chronic phase in which symptoms relate to stenosis or occlusion of vessels. We here report a rare case of Japanese male patient with a fever of unknown origin, and showed a solitary stenosis in the short segment of right axillary artery.
