There no intra- or extra-axial mass lesions, acute hemorrhages or collections. There is a poorly defined low attenuation region within the left side of the pons.

There is a focal area of restricted diffusion demonstrated within the left hemi-pons in keeping with an acute infarct.
From the case:
Pontine stroke - basilar artery stenosis

CTA demonstrates a high grade stenosis of the basilar artery 10 mm above the vertebral basilar junction. A moderate stenosis is also present at the level of the origin of the left PICA. The right vertebral artery demonstrates only very tenuous flow in the mid-portion of its V4 segment, without convincing flow seen across the vertebral basilar junction, or indeed the V3/V4 junction.
