Synopsis

Carcinomatous meningitis results from the spread of cancer cells into the leptomeninges, the subarachnoid space surrounding the brain and spinal cord. It typically occurs from metastasis of neoplastic cells from a primary tumor site, mostly commonly breast or lung cancer or melanoma, and occurs in 5% of patients with these cancers. Carcinomatous meningitis can also occur after seeding of the subarachnoid space from a primary brain tumor such as a medulloblastoma.

Symptoms include headache, neck or back pain, altered mental status, seizures, weakness, and sensory disturbances. Fever is typically absent. Multiple cranial neuropathies, particularly in a patient with a known cancer diagnosis, should raise concerns for this condition. Prognosis is poor, and median survival with treatment is less than 6 months.
