Pigmented schwannoma of the ventral spinal cord

Pigmented schwannomas of the spinal canal are rare entities. We present a c ase of such in an unusual, ventral intradural, extramedullary location in a 27-year-old man, Imaging and histopathologic findings, including electron microscopy, showed an intradural, extramedullary pigmented schwannoma, dens ely adherent to the leptomeninges of the anterior median septum. This lesio n is demonstrative of the neuroectodermal origin of these lesions and repre sents a rare location of these tumors.
