Diffuse axonal injury (DAI) is characterized by widespread axonal damage due to shearing forces by acceleration, deceleration, or rotation of the brain.1Diffuse axonal injury is the most frequent cause of poor clinical outcomes in patients with traumatic brain injury.1However, conventional brain magnetic resonance imaging is not sufficiently sensitive to diagnose DAI, as most DAI lesions are microscopic.2Recent advancements in diffusion tensor tractography (DTT) have allowed the fornix to be visualized 3-dimensionally.3- 5 Wang et al5 demonstrated that the fornix bodies of patients with DAI were injured using the data obtained from DTT. In the current study, we describe a patient with DAI who showed a fornix injury on DTT.
