An 18-year-old man is evaluated for recurrent headaches 1 week after falling on his head during a soccer match at his high school. The patient reports being “dazed” for 15 minutes after the fall but never losing consciousness. Findings from a sideline examination were unremarkable, and the patient was removed from play.
