Solitary ectopic intracerebral schwannoma.

Intracerebral Schwannoma is a rare tumour which can mimic meningioma clinically, radiologically and morphologically. Immunohistochemical techniques are necessary to confirm the Schwann cell origin of the tumours. We report such a tumour in the posterior frontal parasagittal region. The origin of Schwann cells in the central nervous system is still speculative and various postulations are discussed.
