Web8 mrt. 2024 · Hydrocephalus is a neurological disorder caused by an abnormal buildup of cerebrospinal fluid in the ventricles (cavities) deep within the brain. This excess fluid causes the ventricles to widen, putting harmful pressure on the brain's tissues. Hydrocephalus may be present at or shortly after birth, or may result over time from damage or injury. WebFeatures on CT scans that characterize NPH are the presence of bigger temporal horns, ventriculomegaly that is out of proportion to sulcal enlargement, and brain tissue shrinkage. Findings on MRI that are suggestive of NPH are transependymal resorption (Figure 2), 34 T2-weighted increased intensities in brain parenchyma next to the ventricles ...
