Abstract

LOPEZ-BRAVO, A et al. Abiotrophia defectiva, an infrequent cause of cardioembolic stroke. Anales Sis San Navarra [online]. 2020, vol.43, n.3, pp.423-427.  Epub June 21, 2021. ISSN 1137-6627.  https://dx.doi.org/10.23938/assn.0881.

Abiotrophia defectiva is a rare cause of endocarditis with a high embolization rate compared to other streptococcal endocarditis. Neurological complications may occur in 20-40% of cases, and include intracranial aneurysms and subarachnoid hemorrhage. Its isolation in the central nervous system (CNS) is extremely rare and is associated with previous neurosurgical procedures. We present the case of a 51-year-old patient who suffered an ischemic stroke as a complication of A. defectiva endocarditis, and the cases of CNS infections caused by this microorganism are reviewed. The relevance of the case lies in its singular character, due to the absence of previous valve disease in the patient without a recent history of invasive procedures or surgical interventions.

Keywords : Abiotrophia defectiva; Central nervous system; Infectious endocarditis.
