A 54-year-old woman with leukemia, changes in consciousness, and ataxia. A 54-year-old woman with leukemia, changes in consciousness, and ataxia. FLAIR axial images (11,000/140/2 [TR/TE/NEX]). A, The prepositus hypoglossal nuclei show symmetric high-signal-intensity alterations (arrows). B, The medial vestibular nuclei show symmetric hyperintense lesions (arrows). C, Symmetric high-signal-intensity alterations in the facial nuclei (arrows) are detected. Subtle signal-intensity alterations in the abducens nuclei are seen (arrowheads). D, The tectum of the midbrain and the periaqueductal gray matter shows signal-intensity alterations (arrow). E, The mamillary bodies (arrows) show signal-intensity alterations. F, Note signal-intensity alterations (arrows) of the medial thalami and periventricular region of the third ventricle. G. Zuccoli et al.
