Clivus fractures have a high mortality rate due to their proximity to the Brainstem and the Basilar artery[^1]. Clivus fractures are classified into three categories according to the course of the fracture[^1] [^2] [^3]:
Longitudinal clivus fractures
These fractures have a longitudinal fracture line along the Clivus and carry a high risk of injury to or occlusion of the basilar artery[^4], as well as posttraumatic aneurysm formation.
Transverse clivus fractures
Transverse clivus fractures are associated with disturbances of the anterior circulation.
Oblique clivus fractures
Clivus fractures are frequently associated with Diabetes insipidus, Cerebrospinal fluid leak, bitemporal hemianopia, cranial nerve deficits involving cranial nerves III through VI, as well as posttraumatic Aneurysms[^2].
