Case contributed by Dr Ian Bickle

Patient Data

Age: 75
Gender: Female

Dense basilar artery, in keeping with the hyperdense artery sign.

Acute infarcts in all anatomical areas supplied by the branches of the basilar artery:   brainstem, pons, midbrain, cerebellar hemispheres and both occiptal lobes.

Case Discussion

Uncommon and in most cases fatal, basilar artery thrombosis is a devstating diagnosis. 

The diagnosis may be difficult and need close clinico-radiological correlation.  In this case the end organ damage is already apparent.

Infarction is shown in the most graphic of manners demonstrating the distribution of all branches of the basilar artery.

The basilar artery is also dense in keeping with the hyperdense artery sign, due to thrombus within, a phenomenon more commonly observed in MCA thrombosis.
