There is a well defined heterogeneous intra axial mass in the left cerebellar hemisphere. This demonstrates heterogeneous T2 and FLAIR signal - predominantly hyperintense centrally and predominantly hypointense peripherally. Areas of high intrinsic T1 signal centrally and peripheral blooming on susceptibility sensitive sequence suggest the presence of blood products. Abnormal signal on diffusion weighted imaging which is difficult to interpret in the presence of blood products. Heterogeneous enhancement in the mass following contrast administration. Surrounding T2 and FLAIR hyperintensity in the left cerebellar hemisphere extending into the left cerebral peduncle. Minor mass-effect on the left lateral wall of the fourth ventricle but no effacement. Established infarcts in right cerebellar hemisphere.
Periventricular T2 and FLAIR hyperintensity, with multiple foci of T2 FLAIR white matter of both hemispheres and in the pons most in keeping with chronic small vessel ischaemic disease. No other parenchymal abnormality or other region of abnormal enhancement.
Well-defined enhancing mass in the left cerebellar hemisphere with intrinsic T1 hyperintensity and blooming on susceptibility sensitive sequence suggesting haemorrhage. Appearance most likely represents a solitary hemorrhagic metastasis.
