MRI detection of cerebral lesions in post-traumatic anisocoria: specificity and prognostic significance

Overall, the study demonstrated that there is a significant correlation between midbrain lesions and post-traumatic anisocoria in unconscious trauma patients. A brainstem lesion in this case can be assumed to be a pathomorphological correlate of anisocoria. The rate of damage to the midbrain was approximately 50% in cases of transient anisocoria. It can be assumed in this situation that there are functional disorders of the peripheral oculomotor nerve or identifiable/unidentifiable lesions of the brainstem.
