Describes the rare radiological presentation of an intracranial pPNET-ES of the dura with transcalvarial-subgaleal extension.
Adds rare transcalvarial-subgaleal extension to dural pPNET-ES imaging; hypothesis-generating and leaves differential refinement open.
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.
