Abstract
BACKGROUND: Strokes associated with roller-coaster rides are unusual. PATIENT: A previously healthy 4-year-old boy developed acute onset of left-sided weakness when flying home from a trip to an amusement park. He had frequented two roller coaster rides the day prior. Upon evaluation, he was found to have an acute right middle cerebral artery territory infarction. RESULTS: Cerebral angiography showed dissection of the right cervical internal carotid artery and right middle cerebral artery occlusion involving the M1 segment. He was treated with aspirin. Evaluation for underlying connective tissue diseases was unremarkable. CONCLUSION: We speculate that repetitive forces of acceleration and deceleration may have led to a cervical internal carotid artery intimal tear, followed by thromboembolism. It remains uncertain what the threshold of susceptibility to repetitive rotational changes and tolerability to G forces in an otherwise healthy child truly is. Published by Elsevier Inc.
