  • speech difficulties
  • decreased coordination, clumsiness, falls

• fever (sometimes)
• lethargy
• general ill feeling (malaise)
• eyes, pupils different size

Note: Specific symptoms vary. Symptoms commonly seen with most types of metastatic brain tumor are the symptoms caused by increased pressure in the brain.

Signs and tests:

An examination reveals focal (localized) or general neurologic changes that are specific to the location of the tumor. Signs of increased intracranial pressure are also common. Some tumors may not show symptoms until they are very large and then cause rapid neurologic decline. The original (primary) tumor may already be known, or it may be discovered after examination of the tumor tissues indicates that it is a metastatic type of tumor.

• A head CT scan or MRI of the head confirms the diagnosis of brain tumor and localizes the tumor.
• Cerebral angiography may occasionally be performed. If performed, it may show a space-occupying mass, which may or may not be highly vascular (filled with blood vessels).
• A chest X-ray, mammogram, and other tests are performed to look for the original site of the tumor.
• An EEG may reveal focal (localized) abnormalities.
• An examination of tissue (removed from the tumor during surgery or CT scan-guided biopsy) is used to confirm the exact type of tumor. If the primary tumor can be located outside of the brain, the primary tumor is usually biopsied rather than the brain tumor.
