Non-enhanced CT study shows multiple hypoattenuated foci involving both cerebellar hemispheres, more on the left side, associated with mild oedema and mass effect. The examined distal left vertebral artery, including its intracranial segment, appears hyperattenuated, giving a picture impressive of hyperdense artery sign suggestive of embolic infarctions.
Questionable hypodensity is also seen in the left posterior aspect of the medulla oblongata which raises concern for infarction.
