Primary central nervous system (CNS) melanomas are rare tumors arise from precursor leptomeningeal melanocytes that are scattered throughout the arachnoid membranes. The nodular form of primary CNS melanoma manifests as a solitary, discrete neoplasm with a predilection for the spinal cord and posterior fossa. Around 100 cases of primary CNS melanoma reported in the literature. Here, we report the first case in Saudi Arabia of a 55-year-old man who presented with nausea, vomiting, and sudden loss of consciousness. CT brain with contrast showed a left temporal lesion, which was resected and histologically proved to be primary CNS melanoma.
