Primary leptomeningeal malignant melanoma is rare entity. We present a case of primary leptomeningeal malignant melanoma of 66-year-old male, who had suffered severe headache, confusion, and right hemiparesis. The brain computed tomography and magnetic resonance image revealed a well enhancing mass with hemorrhage in the left fronto-parietal region. Total surgical removal of the lesion was performed without neurological deficit. He died at home 6 months after operation. Probably, it seems that the cause of death was poor general condition due to obtunded mentality or brain herniation due to increased intracranial pressure. The literature on this subject is briefly reviewed.
