Abstract

Arare case of primary malignant melanoma of central nervous system in 12-month-old infant with neuro-cutaneous melanosis is presented. Primary malignant melanomas in central nervous system are very rare in children, however, it is known that leptomeningeal melanosis is malignant in 40-50% with neurocutaneous melanosis. Spinal MRI, brain CT and MRI showed diffuse intradural extramedullary mass of entire spinal cord and enhancing mass in brain stem. CSF cytology revealed abnormal cells. Biopsy from leptomeninges of posterior fossa was compatible with malignant melanoma.
