Melanotic schwannoma is a nerve sheath tumor composed of melanin –
producing cells with ultrastructural features of Schwann cells, which is very
rare.
These tumors can appear intracranially and less common in the spinal
canal.
The prognosis is usually good although cases with metastases and death are
described in the literature.
We present the unusual and rare case of a young man with a spinal melanotic
schwannoma at L5/S1 who presented 30 months later with an intracranial melanotic
schwannoma.
Keywords: melanotic schwannoma, MRI, spinal tumor, trigeminal schwannoma
