Extrapontine myelinolysis caused by rapid correction of pituitrin-induced severe hyponatremia: A case report

Figure 2 Brain magnetic resonance imaging during hospitalization. A: Initial brain magnetic resonance imaging (MRI) obtained 3 d after neurological deterioration displayed low signal intensity in the bilateral symmetric basal ganglia (the white arrows) on the axial T1-weighted MRI; B: High signal intensity (the white arrows) on the axial T2-weighted images; C: No lesion in the pons; D-F: Follow-up brain MRI performed one month after treatment. E: Compared to the previous brain MRI, a markedly decreased signal was observed on the T2-weighted image, indicating a significant improvement.
