Brain abscess due to infection by pseudomonas

A case of solitary brain abscess in a 60-year-old woman is presented. MRI scan confirmed the clinical impression and showed an abscess in the right fronto-parietal region, the central sulcus. The longest diameter of the abscess was about 3 cm and it was easily localised intra-operatively under ultrasound guidance and successfully aspirated. The cultured pus grew pseudomonas vesicularis. The rarity of this neurologic pathogen is discussed.
