Cerebellar abscess: the impact of computed tomographic scanning.

Thirty-four cases of cerebellar abscess, diagnosed by computed tomographic (CT) scanning, were managed according to a standard protocol during a 4-year period. Triple high dosage intravenous antibiotics were used, open catheter drainage of the abscess was instituted, and external ventricular drainage was added if obvious hydrocephalus was present. Seventeen patients made a good recovery, and five remained minimally disabled. Ten patients died, and two were left severely disabled. A relationship between the level of consciousness on admission and final outcome was established. In addition, two particular CT scan features (viz. the presence of hydrocephalus and the stage of the abscess) were significant adverse prognostic factors.
