In order - T2 axial, FLAIR (sag, axial, coronal), post Gadolidium T1 axial.
Cystic lesion with fluid similar to CSF (as seen on FLAIR sequences). A solid component which is enhancing on Post GAD is seen in the periphery of the lesion.
This is typical of a cerebellar haemangioblastoma.
Differential diagnosis: pilocytic astrocytoma. However will not expect this kind of enhancement on periphery.
