12 sty 2024 · Communicating hydrocephalus is commonly used as the opposite of obstructive hydrocephalus, which leads to much unnecessary confusion, as most causes of communicating hydrocephalus do have an element of obstruction to normal CSF flow / absorption.
15 lut 2020 · Brain MRI in a patient with communicating hydrocephalus. Axial T2-weighted images (a–c) show ventriculomegaly involving the supratentorial and infratentorial ventricular cavities. Observe the presence of flow voids inside the aqueduct and fourth
12 sie 2024 · Although it is widely believed that defective absorption of CSF at the arachnoid granulation is the cause of communicating hydrocephalus; however, obstruction between spinal subarachnoid space and basal cisterns or between the basal cisterns and arachnoid villi are more common.
This axial (cross sectional) illustration of the brain shows disproportionate enlargement of the ventricular system which is out of proportion to the degree of atrophy. This condition is called communicating hydrocephalus or normal pressure hydrocephalus (NPH).
8 maj 2018 · Communicating hydrocephalus. True communicating hydrocephalus has no obstruction within the ventricular system, within the basilar cisterns, cortical subarachnoid space, or at the arachnoid granulations. Treatment depends upon etiology. CSF Overproduction. CSF overproduction by a choroid plexus tumor or hyperplasia is exceedingly rare.
22 sie 2019 · Communicating hydrocephalus is defined as a CSF flow circulation abnormality outside the ventricular system that produces an increase in the ventricular size. Most cases are secondary to obstruction of CSF flow between the basal cisterns and brain convexity and...
1 lis 2009 · Comparing the number of noncommunicating cases by using the conventional and 3D-CISS images, we found 26 new cases (19.4%) of 134 cases that were previously misdiagnosed as a communicating hydrocephalus on conventional images.
