ABSTRACT

Aggregatibacter aphrophilus is a gram-negative coccobacilli, part of the normal mucosal flora. It rarely causes a brain abscess. We report the case of a 68-year-old woman diagnosed with a brain abscess presenting with vertigo, ataxia and bilateral right hemianopsia. The patient underwent a dental procedure two months before symptoms began. The abscess was removed by neuronavigation-assisted left parieto-occipital craniotomy. A posterior transesophageal echocardiogram demonstrated aortic valvular vegetations. She was treated with meropenem. We reviewed the current literature, finding 19 additional cases of abscesses caused by Aggregatibacter. We found at least 33% of the patients reported had a history of contact with dogs or a dental procedure.
