To evaluate the clinical significance of optic chiasmal edema (OCE) observed in hydrocephalus. aqueduct stenosis), there may be almost no symptoms despite massive dilatation of the ventricles. Therefore, increased D av may be a clinically useful sign of hydrocephalus, and it may prove useful in cases with equivocal clinical or imaging findings. If the condition is caused by a temporary block, and no symptoms have formed from the condition, then there may be no requirement for intervention. She also experienced progressive blurring of vision. a web across the aqueduct causing aqueduct stenosis will only be visible on dedicated high-resolution MRI images). Both CT and MRI (and ultrasound in the neonatal period) can demonstrate most of the features, although the underlying cause may be more or less easily discernible (e.g. most tectal gliomas), and as such permanent CSF diversion may be required. Presentation. Obstructive hydrocephalus is a term usually used to denote obstructive non-communicating hydrocephalus. Obstructive hydrocephalus treatment depends on the severity and the cause of the condition.

Locked-in syndrome in a patient with acute obstructive hydrocephalus, caused by large unruptured aneurysm of the basilar artery (BA). BACKGROUND AND PURPOSE: Hydrocephalus causes transependymal resorption of spinal fluid that in turn produces periventricular interstitial edema. The traditional bulk flow model of CSF posits that CSF is secreted by choroid plexus epithelium in the ventricles, flows through the ventricular system, enters the spinal and cerebral subarachnoid spaces, and is absorbed by the arachnoid granulations into the superior sagittal sinus, to enter the systemic venous system. Also known as non-obstructive hydrocephalus, communicating hydrocephalus occurs when the flow of cerebrospinal fluid (CSF) is blocked after it exits the ventricles. Diagnostic radiology and radiotherapy, No. An important caveat to be aware of is that in acute obstructive hydrocephalus in young patients only minor ventriculomegaly may be visible despite the significant elevation of intracranial pressure.
