A 21-year-old woman presented with hyperemesis gravidarum, changes in consciousness, and ocular abnormalities.A, Sagittal T2-weighted image (4447/100/4 [TR/TE/NEX]) shows high signal intensity of the lower tectal plate (black arrow), dorsal upper medulla (black arrowheads), and mamillary body (white arrow).B, Symmetric involvement of the prepositus hypoglossal nuclei (white arrows) is demonstrated on an axial FLAIR (11000/140/2 [TR/TE/NEX]) image.C, Alterations in the tectal plate (white arrows) and mamillary bodies (white arrowheads) are seen.D, Axial FLAIR image at the level of the basal ganglia shows alterations of the medial thalamic nuclei (white arrows).E-G, Twelve days after the start of thiamine replacement therapy, regression of neurologic symptoms and FLAIR abnormalities is seen.
