Low grade glioma: An Update for Radiologists

With the recent publication of a new World Health Organization (WHO) brain tumour classification that reflects increased understanding of glioma tumour genetics there is a need for radiologists to understand the changes and their implications for patient management. There has also been an increasing trend for adopting earlier, more aggressive surgical approaches to low grade glioma treatment. We will summarise these changes, give some context to the increased role of tumour genetics and discuss the associated implications for radiologists of their adoption. We will discuss the earlier and more radical surgical resection of low grade gliomas and what it means for imaging patients.
