Figure 2. T2-weighted axial brain MRI of our patient.

(A) The first MRI, made during the first admission four days after the correction of hyponatremia, in which no significant abnormalities were observed. (B) The second MRI, made more than three weeks after the first MRI towards the end of the second admission, in which a clearly increased signal intensity is visible in the pons (denoted by →), characteristic for an osmotic demyelination syndrome.
