Imaging findings in the case report 2. Axial FLAIR MRI scans (A) at the time of symptom onset showing multiple hyperintense “snowball” lesions in the white matter. Axial average diffusion-weighted scans (B.I) at the time of symptom onset and apparent diffusion coefficient maps (B.II), with small areas of restriction of diffusion (hypersignal in B.I and hyposignal in B.II), corresponding to small infarctions. Black blood MRI scans at the time of symptom onset (C.I), detecting microangiopathy (multiple small hypersignal nodules of small vessel walls) in both supra- and infratentorial region; and after 6 months (C.II), with regression of the initial pathology, but development of substantial atrophy.
