FLAIR/T2 hyperintense and enhancing extra-axial mass centred at the floor of the fourth ventricle and extending caudally through the left foramen of Luschka and foramen of Magendie and toward the right foramen of Luschka. No appreciable intra-axial component. No flow voids are demonstrated, however there is a small volume of intrinsic T1 signal at its margins with corresponding moderate haemosiderin staining which extends to the adjacent sulci of the cerebellar vermis and hemispheres. No abnormal diffusion restriction nor hydrocephalus. No other abnormal focus of enhancement elsewhere identified within the brain.
MRI whole spine (not shown): normal.
MR features and location of the tumour are most in keeping with an ependymoma.
