Takayasu's arteritis after a prolonged course of hypertrophic osteoarthropathy.

Abstract

A 71-year-old male with hypertrophic osteoarthropathy was referred to our hospital because of a nocturnal fever and tenderness stretching from the left parotid region to the left front neck, in which antibacterials were ineffective. He was diagnosed with Takayasu's arteritis following findings of contrast-enhanced computed tomography and neck ultrasound. This is the first report to describe the development of Takayasu's arteritis after a prolonged course of typical hypertrophic osteoarthropathy, and the proposed hypertrophic osteoarthropathy and Takayasu's arteritis have common underlying pathophysiological factors.
