Takayasu arteritis masquerading as brucellosis: a case report.

This study reports a unique case of a 19-year-old male with Takayasu arteritis initially misdiagnosed as brucellosis due to persistently positive brucella serology. Despite multiple anti-brucellosis treatments, symptoms persisted until the correct diagnosis of Takayasu arteritis was made, Subsequent immunosuppressive therapy for Takayasu arteritis led to symptom improvement and normalization of serological markers. This highlights the challenge of distinguishing between these conditions and the potential for immunosuppression to impact brucella serology in such cases.
