Popis: Abstract Introduction Aggregatibacter paraphrophilus (former name Haemophilus paraphrophilus) is a normal commensal of the oral flora. It is a rare cause of hepatobiliary or intracerebral abscesses. Case presentation We report a case of a 53-year-old Caucasian man with a liver abscess and subsequent brain abscesses caused by Aggregatibacter paraphrophilus. The probable source of the infection was the oral flora of our patient following ingestion of a dental filling. The presence of a large patent foramen ovale was a predisposing factor for multifocal abscesses. Conclusion In this case report, we describe an unusual case of a patient with both liver and brain abscesses caused by an oral commensal Aggregatibacter paraphrophilus that can occasionally show significant pathogenic potential.
