title: Case Report: Intracranial peripheral primitive neuroectodermal tumor - Ewing's sarcoma of dura with transcalvarial-subgaleal extension: An unusual radiological presentation.
abstract: The occurrence of the intracranial, peripheral, primitive, neuroectodermal tumor, Ewing's sarcoma (pPNET-ES) of the dura, is very rare. Immunophenotypical as well as genetic analyses play key roles in its diagnosis and differentiation from central PNET. We describe here the CT scan and MRI findings of an interesting case of intracranial pPNET-ES arising from the anterior falx cerebri with a trancalvarial-subgaleal extension.
