title: A roller coaster headache: case report.
abstract: There are few reports of adverse outcomes associated with roller coaster rides. We present the case of a 26-year-old man who complained of a gradually worsening headache following a roller coaster ride. A computed tomographic scan of the head demonstrated bilateral chronic subdural hematomas. The clinical course and probable mechanism of injury are reviewed.
