Direct bone erosion Hyperemic decalcification - acute infection Resorption by cholesteatoma or osteitis - chronic infection 2. Thrombophlebitis From lateral sinus to cerebellum From superior petrosal sinus to temporal lobe 3. From normal anatomical pathways Oval and round windows , cochlear and vestibular aqueducts, dehiscence of tegmen tympani etc 4. Non anatomical bony defects Accident/ surgery/neoplasm 5. Into brain tissue along the periarteriolar spaces of Virchow-Robin Abscesses in relation to mastoid 1. Sub- Periosteal mastoid Abscess 2. Bezold Abscess 3. Citteli’s Abscess 4. Luc Abscess 5.
