Transverse clivus fracture: case presentation and significance of clinico-anatomic correlations.
BACKGROUND
Bilateral transverse basal skull fractures resulting from lateral crushing injuries involve fractures of the clivus that present clinically with multiple cranial nerve injuries and possible delayed vascular injuries due to the tight neural and vascular entry and exit routes present in this region. A case of a young patient with an extensive basal skull fracture is presented with description of the clinical signs and symptoms in relation to the neuroradiological findings. Clinico-anatomic correlations have been reiterated.


METHODS
A case of a young patient suffering a bilateral crush injury resulting in a basal transverse clivus and petrous bone fracture is presented. Multiple cranial nerve injuries, unilateral and bilateral, were present (CN III, VI, VII). This clinical presentation correlated well with the anatomical location and extension of the respective cranial nerves at the level of the skull base and along the fracture line extending bilaterally through the clivus and petrous bone.


CONCLUSIONS
Initial neurological and neuroradiological investigations should be aimed at promptly detecting cranial nerve injuries and their correlating fracture injuries at the skull base. The possible development and progression of delayed neurological deficits should also be kept in mind and investigated.
