In brief: Sports-related head injuries are relatively common among both amateur and professional athletes. Although most of these injuries are not severe, they occur in a wide variety of sports at all levels of participation. Diagnostic imaging for these injuries has increased in importance over the past decade, and techniques have become more sophisticated and accessible. The authors present a case report of intracranial trauma in a competitive cyclist and describe the various imaging methods—computed tomography, magnetic resonance imaging, plain film radiography, and angiography—used to evaluate head injuries. Computed tomography is emphasized because it is more widely used than the other methods.
