[Endocarditis caused by Brucella melitensis on a mitral valve prosthesis presenting as an ischemic cerebrovascular accident].

A new case of endocarditis by Brucella melitensis on a mitral valve prosthesis in a 15 year old patient, whose first manifestation was an ischemic cerebrovascular accident is reported. The patient presented with daily fever only two months later. Medical treatment alone was not sufficient to avoid valvular failure and substitution of the prosthesis was required. The clinical manifestations and complications of this infrequent condition is discussed. Treatment, which often requires the combination of surgery and antibiotics administered over a prolonged period, is highly recommended.
