Primary malignant brain tumours are rare with high mortality rate. Management and prognostication of these tumours remain as the greatest challenge in oncology. Correct identification of the lineage of origin and also differentiating primary from secondary neoplasms constitute the basis for definitive management of these tumours. In many cases the clinical profile, neuroimaging studies, and histological appearances of the tumour may not be diagnostic of a particular neoplasm.
