Abscesses that develop as a result of direct spread of infection from the frontal, ethmoidal, or sphenoidal sinuses and those that occur due to dental infections are usually located in the frontal lobes. The most common pathogens in brain abscesses associated with paranasal sinusitis are microaerophilic and anaerobic streptococci, Haemophilus spp., Bacteroides spp. (non-fragilis), and Fusobacterium spp. The most common pathogens in brain abscess from dental infections are streptococci and Prevotella and Porphyromonas (formerly Bacteroides) spp.

The majority of brain abscesses associated with otitits media and mastoiditis occur in the temporal lobe and cerebellum and are caused by streptococci, Bacteroides spp. (including B. fragilis), P. aeruginosa, and Enterobacteriaceae.
