title: Diagnosis of a posterior fossa tumour by magnetic resonance imaging.
abstract: The application of magnetic resonance imaging as a diagnostic tool for diseases of the central nervous system is described in the case of a 17-year-old girl who presented with neurological symptoms in January 1986. A comparison is made with the results of computed tomography in the diagnosis of the disease, which proved to be a grade-III glioma that appeared as a lesion of the posterior fossa. The patient recovered uneventfully after radiotherapy. It is suggested that MRI should be considered seriously as a first line of investigation in any suspected lesion of the posterior fossa.
