The term obstructive hydrocephalus usually indicates non-communicating hydrocephalus, and occurs when the flow of CSF is blocked along one or more of the narrow apertures connecting the ventricles [5]. Postradiation encephalopathy. Background. In the low-risk participants, Fjell and colleagues saw the greatest atrophy in the default-mode network (DMN), a series of interconnected brain regions that become more active when the mind is at rest and unfocused. Most prominent MRI features of PSP: atrophy of the midbrain with the hummingbird sign on sagittal images due to preserved pontine volume (a, black arrow), associated to cerebellar atrophy and periacqueductal grey matter hyperintensity (b, black arrowheads); mickey mouse appearance of the brain stem on the axial plane (c); midbrain-pons ratio <0 .

PMC In some cases, two procedures are performed: one to divert the CSF and another at a later stage to remove the cause of obstruction (e.g. space. (E) Longitudinal cranial diameter (LCD). But cysts can grow back or fill with fluid after treatment. theYear=now.getFullYear() Enlarged ventricles in the brain may be a sign of normal pressure hydrocephalus. and transmitted securely. In these instances, the ventricles are enlarged, but the pressure usually is normal. In the adult, the total volume of CSF is approximately 150 mL, of which about 125 mL is intracranial and 25 mL is intraspinal. Widening of interhemispheric sulcus is noted. If you or your child has symptoms of an arachnoid cyst, your provider will ask about your health history. Mega cisterna magna is the enlargement of subarachnoid space containing cerebrospinal fluid. The sulci, fissures, basal cisterns and ventricles together form the 'CSF spaces', also known as the 'extra-axial spaces'.
