title: Chronic subdural haematoma after riding a roller coaster.
abstract: We report a 20-year-old man who developed a chronic subdural haematoma (CSDH) after riding a "giant" roller coaster. The patient had a past history of a subdural hygroma, diagnosed six weeks after a motorcycle accident. Three months after this accident, he rode on a roller coaster, but suffered no direct head trauma during the ride. Three weeks later, he developed a CSDH requiring surgical evacuation. Roller coaster riding, associated with high velocities and extreme acceleration/deceleration forces is a modern cause of CSDH in the young, which may be increasing due to ever-faster rides.
