Basilar artery stroke in 65-year-old woman (1)

A 65-year-old woman presented with acute onset ataxia, headaches, bilateral arm numbness, and binocular diplopia. Examination was remarkable for decreased alertness, bilateral sixth nerve palsies, and bilateral upper limb dysmetria. Further deterioration in her level of consciousness prompted an acute CT without contrast, which was normal. MRI showed restricted diffusion in bilateral thalamic, bilateral cerebellar, and right midbrain regions. (Contributed by Dr. Tim Malisch and Dr. José Biller.)
