Increased T2- signal is evident in the ventral and central portions of the pons. These areas also demonstrate rim- enhancement post-contrast as well as restricted diffusion on DWI and ADC. These characteristics are suggestive of an acute pontine infarct.
There is also increased T2- signal evident in the middle cerebellar peduncles and these areas also demonstrate restricted diffusion.
A small calibre basilar artery-tip flow void is evident on the T2- axial sequence and there is absence of a basilar artery flow- void at the level of the cerebellopontine angles. There is also absence of a right vertebral artery flow void.
There are no bleeds and only a small ovoid area of "blooming" is evident in the right parietal lobe at the grey/white matter interface which is not seen on the CTs.
