There have been few cases described worldwide. This entity carries a potential risk of basilar artery stenosis or occlusion, resulting in ischaemia and infarction of the brainstem and cerebellum. Images study such as computed tomography (CT) and MRI plays a crucial role in diagnosing this condition. We report a rare case that shows entrapment of the basilar artery into the sphenoid sinus, after a traumatic skull base fracture, without infarction of the brainstem and cerebellum, with CSF fistula.}
