Basilar artery herniation into the sphenoid sinus resulting in pontine and cerebellar infarction: demonstration by three-dimensional time-of-flight MR angiography.
We report a unique case of basilar artery herniation into the sphenoid sinus caused by a traumatic skull base fracture, with persistent patency of the basilar artery. Clinical and imaging features, as well as the relevant literature, are described.
