Figure 1.

A 54-year-old male who showed loss of consciousness for seven days after a pedestrian–car accident does not show any lesions in (A) T2-weighted, (B) fluid attenuation inversion recovery (FLAIR), and (C) susceptibility-weighted imaging (SWI). However, diffusion tensor tractography results show neural injuries (discontinuations (green arrows): the left fornical crus and right anterior cingulum) of the fornix (D) and cingulum (E); these injuries are consistent with the subject’s cognitive impairment, which developed after head trauma.
