Abstract

The incidence of brain abscess was studied on all cases occurring in residents of Olmsted County, Minn., from 1935 through 1981. Thirty-eight cases (9 cases first diagnosed at autopsy) were identified and followed through the Rochester Olmsted County medical record-linkage system at the Mayo Clinic. The incidence rate was 1.3/100,000 person-years (PY), 1.9 in males and 0.6 in females. Incidence decreased from 2.7 in 1935–44 to 0.9 in 1965–81. Rates were higher in children 5–9 years old (2.4) and after age 60 (2.6 PY). An etiologic agent was identified in 29 cases (76%) with streptococci being the most frequently isolated. Case-fatality ratio was 38% (11/29), stable over time. Concurrent bacterial meningitis was the strongest predictor of death. Neurologic sequelae were observed in 8 (44%) of the 18 surviving patients including epilepsy (5 cases), deafness and motor impairment.
