case_images: On April 11, 2022, cranial magnetic resonance imaging (MRI) revealed high-signal intensities in the bilateral parieto-occipital lobes and the right temporal lobe on T2-FLAIR sequences. Additionally, diffusion-weighted imaging (DWI) demonstrated localized areas of high signal. Susceptibility-weighted imaging (SWI) within the brain parenchyma did not detect any noticeable abnormal low-signal intensities. The neuroimaging features are highly suggestive of PRES syndrome diagnosis. The red arrows indicate lesion locations.

case_images: Based on these imaging findings, reversible posterior white matter encephalopathy was considered (see Figure 1).

case_images: We observed that the patient's urine darkened to a dark brown color when exposed to sunlight (see Figure 2).
case_images: On April 28, 2023, cranial magnetic resonance imaging (MRI) revealed high-signal intensities in the bilateral parieto-occipital lobes and the right temporal lobe on T2-FLAIR sequences, while DWI sequences demonstrated localized areas of high signal. The extent of these signals has significantly decreased compared to the previous examination conducted on April 11, 2023.

case_images: On April 28, 2023, the patient's repeat cranial brain MRI revealed a significant decrease in the extent of the abnormal signal in the bilateral parietal-occipital lobes and right temporal lobe compared to the previous scan (see Figure 3).
