Arachnoid Granulations and Arachnoid Villi in Mammals
There has been no general agreement regarding the presence of arachnoid granidations and arachnoid villi in mammals. This seems to have arisen from the fact that various workers have used different criteria in distinguishing between the two terms — 'granula tion' and 'villus'. Luschka (1852) was the first to. define the structure observed macroscopically as an 'arachnoid granulation', while fo...
متن کاملIntracranial hypertension and giant arachnoid granulations.
We read with great interest the article by Arjona et al concerning a patient with intracranial hypertension (ICH) and giant arachnoid granulations (GAG). The patient was a non-obese male without known risk factors for ICH apart from left transverse sinus hypoplasia and several GAGs in both transverse sinuses. The authors suggested that arachnoid granulations (AGs) might be responsible for ICH b...

متن کاملArachnoid granulations may control heat exchange between intracranial dural sinuses and cerebrospinal fluid
Selective brain cooling is a system in a human that protects the brain from hyperthermia. Cool venous blood from head skin and upper respiratory tract drains into intracranial dural sinuses. In that region, cool blood in the dural sinuses decreases the temperature of the cerebrospinal fluid. Cerebrospinal fluid provides brain cooling. All cortical arteries to the brain pass the cerebrospinal fl...
متن کامل[Arachnoid granulations as cause of tegmen tympani defects].
A woman aged 73 presented with a four-week history of hypoacusis and low-density clear discharge from her right ear, with no history of traumatic or surgical events. Physical examination showed right middle ear invasion and discharge of a clear liquid, which was suggestive of CSF caused by tympani defects. Left middle ear invasion presented with no other condition. Computerised tomography (CT) ...
