FIG 2. May 29.
A–C, FLAIR axial images.
A, Red nuclei of the midbrain are hyperintense compared with the brain parenchyma (solid arrows). White matter hyperintensity (open arrow) adjacent to the dilated right lateral ventricle is probably a change due to the abscess cavity.
B, Tectum of the midbrain also shows symmetric hyperintensities (arrows).
C, At the lower pons level, symmetrical hyperintense lesions are also detected in facial nuclei (solid arrows), vestibular nuclei (open arrows), and abducens nuclei (arrowheads) of the pontine tegmentum and cerebellar dentate nuclei (double arrows).
D, T1-weighted sagittal image shows atrophy of mamillary body (arrow).
