WebBackground: Hydrocephalus is a neurological disease with an incidence of 0.3–0.7 per 1000 live births in the United States. Ventriculomegaly, periventricular white matter alterations, inflammation, and gliosis are among the neuropathologies associated with this disease. WebOn MRI, edema produces high signal on T2-weighted imaging and low signal on T1-weighted imaging. Diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) sequences distinguish between cytotoxic edema (restricted diffusion) and vasogenic or interstitial edema (normal or increased diffusion).
