The purpose of this report is to present the case of a National Junior Collegiate Athletic Association football player diagnosed with Chiari malformation postconcussion. A Chiari malformation is characterized by the cerebellum presenting below the level of the foramen. The uniqueness of this case stems from the patient’s health history, length of symptoms, and diagnosis. The effectiveness of treatment options, and the primary means to reduce the risk of catastrophic head injury in those with Chiari malformations are debatable. Clinicians should be familiar with the potential for the presence of a Chiari malformation with persistent symptoms postconcussion.
