An Uncommon Presentation of Brucella Endocarditis Masquerading as Neurobrucellosis

Brucella endocarditis is a rare but a severe complication of brucellosis, observed in less than 2% of cases. It is the main cause responsible for up to 80% of deaths in brucellosis. Herein, we present a case of brucella endocarditis that developed on a native aortic valve, but presented to us with fever for several months and acute neurological symptoms. This case report signifies the importance of considering brucella endocarditis as one of the differentials in patients presenting with Pyrexia of Unknown Origin (PUO) and Central Nervous System (CNS) manifestations.
