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 کاملGiant arachnoid granulation mimicking dural sinus thrombosis
Arachnoid granulations (AG) are composed of dense, collagenous connective tissue that includes clusters of arachnoid cells. They tend to invaginate into the dural sinuses, through which cerebrospinal fluid enters the venous system. AG are most commonly seen at the junction between the middle and lateral thirds of the transverse sinuses near the entry sites of the superficial veins. Presently de...
متن کاملGiant Thymolipoma Mimicking Cardiomegaly
A 28-year-old man presented with a chest radiograph strongly suggestive for cardiomegaly. Although he did not consent any hemodynamic studies, cardiomegaly was ruled out on the basis of the clinical course. Computed tomography showed the existence of a large mass in both sides of the heart and in both lower hemithoraces. The tumor was resected by anterior mediastinotomy; it was weighted 2100 g ...
