Astrocytic tumours

Astrocytic tumours are primary central nervous system (CNS) tumours. They arise from astrocytes and are the most common glial tumour.

They can be divided into those that are diffuse in growth (the vast majority with poorer prognosis and given a higher grade (see diffuse astrocytoma grading) and those that are localised which tend to have a lower grade. 

Additionally, some tumours also contains astrocytic components, and it is often this component that dictated biological behaviour. Examples include:

All these tumours have strikingly differing imaging appearances, treatment and prognosis and thus they are, along with spinal astrocytomas discussed separately.  

NB: gliomatosis cerebrifibrillary astrocytoma and  protoplasmic astrocytoma are no longer recognised in the current WHO classification of CNS tumours
