case_images: Coma Scale, E1V1M5), anisocoria (right/left: 5.0/3.0 mm), and left hemiplegia. Computed tomography (CT) revealed an acute subdural hematoma (ASDH) on the right side with the midline shift [Figure 1].
case_images: Magnetic resonance images on day 3 revealed the bright tree appearance on the right frontal and parietal lobes at diffusion-weighted images (DWI). That lesion demonstrated low intensity at the apparent diffusion coefficient map image and iso-intensity at the fluid-attenuated inversion recovery (FLAIR) image. (a) DWI. (b) Apparent diffusion coefficient map image. (c) FLAIR image.

case_images: MR images revealed a high signal intensity in the white matter of the right frontal and parieto-occipital lobes on DWI, which was consistent with the so-called BTA [Figure 2a]. The apparent diffusion coefficient (ADC) value in the white matter was reduced [Figure 2b]. However, the intensity in the white matter was normal on fluid-attenuated inversion recovery (FLAIR) images [Figure 2c].
case_images: Magnetic resonance images on day 20 showed the abnormal signal intensity in the white matter of the right cerebral hemisphere completely disappeared on diffusion-weighted imaging (DWI), although the high-intensity area in the right parietal lobe with atrophy was observed on fluid-attenuated inversion recovery (FLAIR) images. (a) DWI. (b) FLAIR image.

case_images: Follow-up MR images on day 20 showed that the abnormal signal intensity in the white matter of the right cerebral hemisphere completely disappeared on DWI [Figure 3a], although the high-intensity area in the right parietal lobe with atrophy was observed on FLAIR images [Figure 3b].
