There is prominent diffusion restriction at the bilateral anterior fornix and in the small nuclei of the right thalamus (possibly the anteroventral nuclei).
Normal MRA with normal ACOM
Case Discussion
The bilateral columns of the fornix are supplied by the subcallosal artery, which mostly originates from the anterior communicating artery (which appears normal in this case).
Additionally, the subcallosal artery also supplies the genu of the corpus callosum and other basal forebrain structures. In this case, the genu of the corpus callosum appears normal. However, it's common to see infarction there in many case reports.
