Abstract

Otogenic brain abscesses account for 31.4% of all cerebral abscesses: bone erosion due to coalescent otomastoiditis or cholesteatomas, osteothrombophlebitis, and hematogenous spreading are the most frequent pathways of infection. We briefly reported and discussed the first case of otogenic brain abscess due to infectious labyrinthitis that (likely) spread intracranially through a dehiscence of the superior semicircular canal.
