a-d. In some patients, severe imaging findings correlated with higher papilledema grade, while in other patients imaging findings were completely discordant with fundus appearance. Overall, no statistical correlation was found between imaging and clinical papilledema grade. MRI of patient A(1a) shows grade 2 enhancement of the optic nerve head OU (severe finding), (and fundus examination of patient A also shows severe grade 5 OD papilledema (1b). MRI of patient B shows grade 3 globe configuration OD (severe finding), (1c) while fundus examination of patient B shows only grade 1 OD papilledema (1d).
