The patient's disorientation, which included passing vague comments and abnormal behavior, increased after admission; cranial magnetic resonance imaging carried out on hospital day 7 showed a high signal intensity area on T2-weighted imaging of the central pontine region (Figure 1a). Cranial magnetic resonance imaging carried out 5 months after hospitalization showed an improved high signal intensity area (Figure 1b), and his neurological symptoms had almost completely disappeared. However, the drop in plasma osmolality and observation of a pre-existing low-density area in the central pontine region on computed tomography (Figure 1c) on admission suggested that ODS had already occurred by the time of admission.
