case_images: Chest x-ray showed pulmonary oedema and bilateral pleural effusion when admission (A). Chest x-ray showed pulmonary oedema and bilateral pleural effusion decreased after TAVR (B).

case_images: Chest X-ray showed pulmonary oedema and bilateral pleural effusion (Figure 1A). Chest X-ray showed decreased pulmonary oedema and bilateral pleural effusion (Figure 1B), but serum sodium increased from 140 to 172 mmol/L (Figure 2).

case_images: Chest X-ray showed decreased pulmonary oedema and bilateral pleural effusion (Figure 1B), but serum sodium increased from 140 to 172 mmol/L (Figure 2).
case_images: CT scan didn't demonstrate any hypodensity in pons 1 day after the operation (A) and 7 days after the operation (B).

case_images: CT brain scans were performed twice to look for lesions in her brain, but they did not reveal any hypodensity on CT images (Figure 3).
case_images: MRI image of the patient's head: Axial T1 weighted images demonstrating symmetric low signal in the central pons (A,E). Axial T2 weighted images demonstrating symmetric high signal in the central pons (B,F). T2 FLAIR images demonstrate symmetric high signal in the central pons (C,G). DWI images didn't show any diffusion restriction in the central pons (D,H).

case_images: T1-weighted imaging and a symmetric high signal on T2-weighted imaging and fluid attenuated inversion recovery (FLAIR) sequence imaging in the pons and medulla oblongata areas, which are called the trident sign or Mercedes Benz sign. This classical radiological picture favors a change in ODS (Figure 4).
