The term meningeal cardnomatosis refers to diffuse metastasis of the leptomeninges by systemic cancer. The diagnosis is suggested by signs and symptoms of headache, dementia, meningeal irritation and involvement of multiple cranial or spinal nerve roots. Blindness as an initial manifestation of meningeal carcinomatosis is very rare without evidence of a primary carcinoma. We describe the clinical course of a patient with meningeal cardnomatosis whose initial symptom was blindness.
