Abstract
Hydrocephalic brain edema has become widely recognized since the introduction of computer tomography (CT). On CT scan, edema is seen especially in the periventricular white matter, where it is familiar as periventricular lucency or periventricular hypodensity (PVH) [13, 14, 17]. Our previous study with metrizamide CT scanning showed transependymal migration of metrizamide in the area of PVH. The iodine concentration was highest in the periventricular white matter according to measurement by the cerate-arsenite method. The specific gravity was particularly low in the periventricular white matter of the hydrocephalic brains in which it was measured by means of a gradient column containing kerosene and bromobenzene. On the basis of these facts edema is interpreted as transependymal migration of cerebrospinal fluid (CSF) into the brain [6–8].
