First Things First (assess & treat for the following)
- Tumors that metastasize to the brain occur in ~10-15% of systemic cancers.
- The cancers w/ the greatest incidence of brain & intracranial metastasis (85%) are:
- The most common cancer to metastasize to the brain
- 50% of the metastases are single lesions.
- 10-30% of advanced breast cancer metastasizes to the brain.
- Usually occurs in younger & premenopausal pts
- Malignant melanoma
- 30-40% incidence of metastatic intracranial tumors
- Usually multiple & hemorrhagic
- Renal cell
- Metastatic tumors also appear to be highly vascular.
- They are more likely to be solitary tumors.
- Colorectal tumors are infrequently metastatic to the brain.
- Solitary metastases most frequently seen in posterior fossa
- Any disease presenting as a space-occupying lesion or cerebral edema is suspect:
- Intracranial abscess
- Intracranial infection: parasitic
- Generalized cerebral edema
