title: MRI of subarachnoid dissemination of medulloblastoma.
abstract: We report two cases with subarachnoid dissemination of medulloblastoma depicted clearly by Gadolinium-DTPA enhanced MRI. We also demonstrate the superiority of Gadolinium-DTPA enhanced MRI over nonenhanced MRI, CT, myelography and postmyelographic CT for diagnosing subarachnoid dissemination and for monitoring the response to therapy.
