Figure 2.
Magnetic resonance imaging of II-1 with combined dHMN-V and cerebral small vessel disease (CSVD). Fluid-attenuated inversion recovery (FLAIR) imaging revealed a hyperintensity (yellow arrow) surrounding the lateral ventricle and the bilateral centrum semiovale. Microbleeds (red arrow) and lacunar infarction (blue arrow) were present in the brainstem as observed using susceptibility weighted imaging (SWI) and T2. Magnetic resonance angiography (MRA) revealed normal intracranial arteries.
