A neurological deficit was detected during the physical?examination so urgent magnetic resonance imaging of the brain?was performed, revealing an intrahemispheric, right positioned solitary?expansive mass with ring enhancement. Purulent material was?obtained during osteoplastic craniotomy with total extirpation of the?brain abscess. Aggregatibacter aphrophilus and Bacteroides uniformis?were isolated. The patient’s general condition improved and the neurological?deficit subsided as a result of the prompt recognition and?treatment of this life threatening condition. Conclusion.
