case_images: The results of brain MRI.. (A) T2-weighted brain MRI showed enlarged lateral ventricles (yellow arrowheads). Evans index (the ratio of the maximum width of the frontal horns of the lateral ventricles and the maximal internal diameter of the skull; blue two-way arrows) was 0.42 (normal-pressure hydrocephalus (NPH) criterion; >0.3). (B) The T2-weighted fluid-attenuated inversion recovery (FLAIR) brain MRI showed enlarged lateral ventricles (blue arrowheads) and third ventricle (yellow arrowhead), but the callosal angle was not narrowed. This patient did not present disproportionately enlarged subarachnoid-space hydrocephalus.

case_images: FIG1
case_images: Brain magnetic resonance imaging (MRI) revealed enlarged lateral and third ventricles and Evans index was 0.42 (NPH criterion; >0.3) (Figures 1A, 1B). In our case, neither narrowing of the callosal angle nor disproportionately enlarged subarachnoid space hydrocephalus (DESH) was observed (Figure 1B).
