Intracranial 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 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 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) ...
متن کاملArachnoid granulations of the posterior temporal bone wall: imaging appearance and differential diagnosis.
Arachnoid granulations are rarely seen on high-resolution CT (HRCT) at the posterior temporal bone wall, where they appear as erosions, without bone spicules and often with a lobulated surface. Differential diagnosis includes endolymphatic sac tumor, paraganglioma, chordoma, and chondromatous and metastatic tumors. MR imaging can confirm the diagnosis because arachnoid granulations behave like ...
