May be upon CD4 count at diagnosis. Surgery also permits the diagnosis to be verified and may be beneficial in reducing intracranial pressure and relieving symptoms even if the neoplasm cannot be completely removed. Metastatic Intracranial Tumors Cerebral Metastases Metastatic brain tumors present in the same way as other cerebral neoplasms, ie, with increased intracranial pressure, with focal or diffuse disturbance of cerebral function, or with both of these manifestations. Indeed, in patients with a single cerebral lesion, the metastatic nature of the lesion may only become evident on histopathologic examination. In other patients, there is evidence of widespread metastatic disease, or Treatment is by irradiation to symptomatic areas, combined with intrathecal methotrexate.
