An unusual case of neonatal brain abscess following Klebsiella pneumoniae septicemia

A case of solitary brain abscess in a term neonate caused by Klebsiella pne umoniae is described. K. pneumoniae, although a common cause of neonatal se pticemia, is rarely implicated as an etiological agent for cerebral abscess in this age-group. The interest of this case lies in the rarity of the cau sative organism and atypical features. In the absence of predisposing facto rs in the neonate, we suspect that the infection was transmitted vertically from the mother before or at the time of delivery since there was evidence of asymtomatic urinary tract infection in the antenatal period.
