[Role of computerized tomography in the diagnosis of encapsulated cerebellar abscesses in acute otitis media].

Two rare cases of encapsulated cerebellar abscesses that developed 2-2.5 months after acute otitis media are described. In both patients, otitis media was cured using conservative therapy although it was aggravated by mastoiditis in one case and antritis in the other. Abscesses were removed by means of a neurosurgical trans-occipital approach. Computer tomography detected "volume formations" in the cerebellum but failed to differentiate between an abscess and tumor. It is concluded that in such cases antrotomy (mastoidotomy) is not necessary.
