Intraparenchymal schwannoma of the frontal lobe.

A 45 year old woman with bifrontal headaches and progressive diminution in vision over 6 months was found to have bilateral papilloedema. CT scan showed large right frontal lesion with surrounding oedema. Right basal frontotemporal craniotomy was performed to excise the multinodular, intraparenchymatous tumor. Hispathology confirmed the diagnosis of schwannoma. Post-operative course was uneventful with disappearance of pre-operative signs and symptoms.
