Brain Abscess Outcomes in the Modern Imaging Era
A new meta-analysis in Journal of Infection examines how CT and MRI have influenced brain abscess diagnosis and treatment, analyzing data from 21,840 patients between 1980 and 2022. The findings show that brain abscess remains more common in men, with Streptococcus spp. (32%), Staphylococcus spp. (14%), and Gram-negative bacteria (9%) as the leading pathogens. Key risk factors include otitis/mastoiditis (27%), immunocompromise (19%), and sinusitis (16%).
