- Mixed solid-cystic lesion with necrosis/liquefaction seen within the solid component. Enhancing wall around the cystic component. Intraaxial location. Bright DWI signal within tumour reflects low ADC due to hypercellularity. No calcification seen (CT). The appearance is indistinguishable from high grade glioma/glioblastoma.
During surgery, the margin is well-circumscribed and the tumour is rubbery/leathery.
