Adults with chronic immunosuppressive conditions are at an increased risk for Streptococcus agalactiae endocarditis, which is typically characterized by acute onset, presence of large vegetations, rapid valvular destruction and frequent complications. We report a rare case of a 74 years old man presenting with fever, renal infarction, ischemic stroke and uveitis. Infective endocarditis was diagnosed and Streptococcus agalactiae was isolated in blood cultures. A multiple myeloma Ig G-K was also diagnosed. The infective endocarditis was successfully treated with a course of benzylpenicillin and gentamicin. The authors highlight the severity of vascular embolic disease present in this case and the diagnostic challenge. They also intend to remind about the association between Streptococcus agalactiae endocarditis and chronic diseases, despite its low reported prevalence.Adultos com doenças imunossupressoras crónicas apresentam risco aumentado de endocardite a Streptococcus agalactiae, caracterizada por clínica de início súbito, vegetações de grandes dimensões, destruição valvular rápida e complicações frequentes. Relatamos o caso de um doente de 74 anos de idade, admitido por quadro febril associado a enfarte renal, acidente vascular cerebral e uveíte, com o diagnóstico subsequente de endocardite infeciosa, tendo-se objetivado bacteriemia a Streptococcus agalactiae. Simultaneamente foi diagnosticado mieloma múltiplo Ig G-K. A endocardite infeciosa foi tratada com sucesso recorrendo a antibioterapia com benzilpenicilina e gentamicina. Os autores destacam a gravidade da doença embólica vascular presente neste caso e o desafio diagnóstico. Pretendem ainda relembrar a associação entre endocardite a Streptococcus agalactiae e as doenças crónicas, apesar da sua baixa prevalência.
