Abstract:
We report a rare case of herniation of a basilar artery into the sphenoid sinus after a traumatic skull base fracture. Computed tomographic angiography, magnetic resonance imaging, and cerebral angiogram demonstrated patency of the basilar artery through the fractured clivus at the time of injury, a very rare occurrence. The following day, the patient developed pontine and cerebellar infarcts. In a patient with clival fracture, we advocate fast assessment of vertebrobasilar system with CTA and early anticoagulation treatment in those with vascular entrapment.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Magnetic Resonance Imaging
Brain Imaging
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
