Demonstrates non-vascular neurologic manifestations of COVID-19. Minimal (a) T2 / (b) FLAIR hyperintensity in the left greater than right olfactory bulbs which correlated clinically with loss of smell in a COVID-19 positive patient. PRES manifesting as asymmetric T2/FLAIR hyperintensities (c) of the occipital lobes which exhibited restricted diffusion on DWI sequences (d). Leukoencephalopathy manifesting as confluent subcortical T2/FLAIR hyperintensity within the bilateral parietal, bilateral occipital, and left frontal lobes (e) is also commonly seen. In many cases as with this patient, microhemorrhages were identified on SWI sequences (f).
