Introduction: Intracranial nerve sheath tumors not arising from cranial nerves are extremely rare, even more, when malignant degeneration. 

Case Report: Female adult presenting cerebellar syndrome and headache. Imaging showed an intracerebellar tumor and surgery was performed. Histopathology and immunohistochemistry were compatible with intracerebellar Triton tumor.

Discussion: Twenty-five malignant intracerebral nerve sheath tumors have been reported in the literature. The presented case is not associated to neurofibromatosis; it is the fourth reported intracerebellar and the first showing rhabdomyoblastic differentiation in this location.

Conclusion: Further studies are required to establish the cell origin and the best management for this entity.
