A Case of "Primitive Glioma": Regarded as a subclass of primitive neuroectodermal tumors

ABSTRACT

Primitive neuroectodermal tumors(PNETs) may be a term established recently for a tumor group(?) which is composed of prominent undifferentiated cells with variable foci of differentiation along glial and neuronal lines. The authors experienced a case of 'primitive glioma' regarded as a subclass of PNETs, in a 14 year old boy who had suffered from headache and vomiting for about 40 days prior to admission. Brain CT and angiographic studies reveal a huge hypovascular mass lesion with multiple cysts in the left frontal lobe. The patient was satisfactorily treated by total tumor excision and following irradiation, and is now in follow up. We present the case with review of the literatures.
