A right medial cerebellar hemisphere 2.3 X 2.2 X 2.1 cm mass lesion is seen, the lesion shows heterogeneously hypointense T1 and hyperintense T2 signal intensity with heterogeneous predominantly marginal and nodular enhancement with central necrosis. The lesion is surrounded by mild to moderate vasogenic brain oedema with some compression of the 4th ventricle and slight downward displacement of the cerebellar tonsils.
At left splenium of the corpus callosum small enhancing lesion is seen with slight hyperintense T1 and hyperintense T2 / FLAIR signal intensity. It measures 1.4 X 0.8 cm.
A small left cerebellar and adjacent middle cerebellar peduncle demyelinating focus of high T2 / FLAIR signal intensity and faint post-contrast enhancement is seen.
A small right posterior parietal periventricular demyelinating focus of low T1 / FLAIR and high T2 signal is seen with no post-contrast enhancement.
