Ependymoma is a rare adult tumor that originates from ependymal cells of the central nervous system, primarily occurring in the cerebral ventricles or the central canal of the spinal cord. In this paper, we report a case of extensive leptomeningeal seeding of ependymoma of a 39-year-old male patient, in whom the tumor was found incidentally after head trauma. The MRI exhibited diffuse leptomeningeal infiltrative lesions along with bilateral multiple cerebral sulci, basal cisterns, cerebellopontine angle, cerebellar folia.

Odontogenic causes account for most etiologies, but there are also unusual causes of MSA.
