Intraparenchymal schwannomas are rare and most of the reported cases are in supratentorial region with frontal lobe being most common. Infratentorial location is very rare. We report a posterior fossa midline large cystic schwannoma with mural nodule mimicking as pilocytic astrocytoma. The pathogenesis and neuroradiological findings of intraparenchymal schwannomas are discussed with review of the related literature.
