(A) I. Patient 1, axial fluid-attenuated inversion recovery (FLAIR) showing hyperintense lesion in posterior pontine tegmentum. II. Saggital FLAIR showing vertical extent of the lesion. III. Diffusion-weighted imaging showing mild diffusion restriction. (B) I. Patient 2, axial dual showing hyperintense lesion in posterior pontine tegmentum. II. Saggital FLAIR showing vertical extent of the lesion. III. Diffusion-weighted imaging showing mild diffusion restriction. (C) I. Patient 3, axial flair showing hyperintense lesion in posterior pontine tegmentum, slightly more significant on the right side. II. Saggital FLAIR showing vertical extent of the lesion, slightly larger than the previous two patients, consistent with there being some slowing of vertical saccades. III. Diffusion-weighted imaging showing mild diffusion restriction.
