CEREBELLAR abscess is apparently a rare complication of otitis media. Only 6 patients with this lesion have been encountered at the Mayo Clinic during the last ten years. Meltzer1 reported only 2 encountered during an eleven year period at the Massachusetts Eye and Ear Infirmary. Courville and Nielsen2 found only 12 cerebellar abscesses in a review of the results of 10,000 necropsies covering a fifteen year period. Despite its infrequent occurrence, this condition occasionally presents itself and knowledge of its various aspects is important.
The routes by which infection may spread from the middle ear and the cells of the mastoid process are conducive to the formation of supratentorial or infratentorial abscesses of the brain. As pointed out by Brunner,3 Atkinson4 and others, there are four possible pathways: 1. The lateral sinus may become thrombosed as a result of being in direct contact with infected cells
