Unexplained fever and aortic regurgitation: a rare presentation of Takayasu's aortitis--a case report

Takayasu's aortitis is rare in male patients. The authors describe the case of a 48-year-old man with a fever of unknown origin, progressive general fatigue, and dyspnea due to aortic regurgitation. A severely thickened aorta was noted during aortic valve replacement. The diagnosis was based on a histologic examination of an operative specimen of the ascending aorta. Takayasu's aortitis should be considered even in male patients with fever of unknown origin and progressive aortic regurgitation.
