title: "How I do it"--otology and neurology. A specific issue and its solution. The diagnosis of a posterior fossa tumor.
abstract: In summary, the patient with a unilateral sensorineural type hearing loss, unilateral tinnitus, or dysequilibrium may have a tumor in the posterior fossa. This is diagnosed by the history, ear nose, throat and otoneurological examination, the audiological studies, electronystagmography, radiological tests using the Compere unit, the CT Scan, and when indicated the posterior fossa myelogram. The list of causes for these symptoms other than tumefaction is large and there are a significant number of cases that remain "cause undetermined." The latter requires diligent follow-up and even consultation elsewhere.
