A case of brainstem contusion due to minor fall trauma

Abstract

In recent years, traumatic injuries in the elderly have been increasing and have been attracting attention as the population ages. According to the Japan Neurotrauma Data Bank, falls are the most common cause of injury, accounting for more than half of all injuries. Severe head injuries are not infrequently encountered in clinical practice. The occurrence of a single brainstem injury is extremely rare, and the mechanism of its occurrence is still under debate. In this case, the head computed tomography (CT) and magnetic resonance imaging (MRI) showed a brainstem injury that extended vertically around the tentorial incisura, and we diagnosed a single brainstem injury caused by direct injury from the tentorial incisura.
