description | PURPOSE: The purpose was to present a case series of vertical gaze paresis in patients with a history of cranioencephalic trauma (CET). METHODS: The clinical characteristics and management are presented of nine patients with a history of CET secondary to motor vehicle accidents with associated vertical gaze paresis. RESULTS: Neuroimaging studies indicated posttraumatic contusion of the thalamic-mesencephalic region in all nine patients who corresponded to the artery of Percheron region; four patients had signs of hemorrhagic transformation. Vertical gaze paresis was present in all patients, ranging from complete paralysis of the upward and downward gaze to a slight limitation of upward gaze. DISCUSSION: Posttraumatic vertical gaze paresis is a rare phenomenon that can occur in isolation or in association with other neurological deficits and can cause a significant limitation in the quality-of-life. Studies in the literature have postulated that the unique anatomy of the angle of penetration of the thalamoperforating and lenticulostriate arteries makes these vessels more vulnerable to isolated selective damage in certain individuals and can cause-specific patterns of CET. |
