Localization of post-traumatic trochlear nerve palsy associated with hemorrhage at the subarachnoid space by magnetic resonance imaging - 03/09/11
, Shinichi Kan, MD c, Kimiya Simizu, MD bAbstract |
PURPOSE: To report evaluation of traumatic trochlear nerve palsy using head magnetic resonance imaging.
DESIGN: Observational case reports.
METHODS: We examined two cases involving trochlear nerve palsy after closed head injury.
RESULTS: Using a fluid attenuated inversion recovery pulse sequence, MRI showed a high-intensity lesion consistent with subarachnoid hemorrhage at the trochlear nerve area in the ambient cisterns.
CONCLUSION: An impact force directed toward the tentorium can be a mechanism of injury in some post-traumatic trochlear nerve palsies. Fluid attenuated inversion recovery pulse sequence is a sensitive method for detection of abnormalities in cases associated with head injury.
