Intracranial malignant melanotic nerve sheath tumor: illustrative case

Melanotic schwannomas have a malignant propensity despite their benign morphology. Immunohistochemical analysis helps confirm the diagnosis of melanotic schwannoma. This is the 21st documented case of an intracranial MMNST, and, given the rarity of the tumor, there is scope for further research and studies on the role of radiotherapy in the management of these tumors. https://thejns.org/doi/10.3171/CASE24473.
