Subdural empyema epidemiology and demographics
Introduction
Overview
Overview
Subdural empyema accounts for approximately 15-25% of focal central nervous system infections. In 2014, the incidence of subdural empyema was estimated to be less than 1 case per 100,000 individuals.[1] Prior to antibiotics, the case fatality rate of subdural empyema was estimated to be near 100%. However, with antibiotics, the current rate is estimated between 10-20%.[2] The disease usually occurs in children and young adults (70% cases occurring in the second and third decades of life), being more frequent in men than women, possibly due to sex-related differences in sinus anatomy.
