Supratentorial Primitive Neuroectodermal Tumors (PNETs)

Supratentorial PNETs are a group of heterogeneous neoplasms which are rarely encountered especially in adulthood. Because of the rarity of these tumors, articles describing the clinical features and their response to treatment are mostly limited to case reports and retrospective studies of relatively small series. In Addition, many of the investigators have analyzed mixed varieties of these heterogeneous tumors found in different age groups. Therefore, it is very hard to assess the clinical features, true effect of various treatment modalities, and prognosis of these tumors. Nowadays, supratentorial PNETs are distinct from medulloblastomas and peripheral PNETs.
