Primitive supratentorial neuroectodermal tumor in an adult

Summary We report the case of a 32-year-old female with a diagnosis of supratentorial tumour. Total removal of the tumour was achieved in a two-stage procedure.

We review the literature and describe the existing knowledge of these tumours
