Malignant lymphoma of the nervous system.

The radiological findings in 22 patients with malignant lymphoma of the nervous system are reviewed in relation to the clinical and histological features. The radiological findings were grouped into four major categories: intracranial, orbital, nasopharyngeal, and spinal. A fifth category, complications, was considered separately. The common neuroradiological manifestations of nervous system lymphoma are reviewed and compared with the recent literature.
