Fatal transorbital penetrating intracranial injury caused by a bicycle hand brake.

A transorbital penetrating intracranial injury is a rare and severe traumatic brain injury. Patients with this type of injury may present dramatically, but often the injury is subtle and therefore easily overlooked and not recognized in the first place. We present the case of a 45-year-old female admitted to the emergency department after she fell with her bike and the bicycle brake handle penetrated her left eye.
