Superior sagittal sinus filling defect in metastatic lung cancer: tumour thrombus, bland thrombus or both? [PDF]

European Journal of Case Reports in Internal Medicine
Background: Cerebral venous sinus thrombosis is an uncommon but potentially life-threatening cause of stroke. In patients with active malignancy, dural venous sinus filling defects present a diagnostic challenge, as they may represent bland thrombosis ...

Reversible giant arachnoid granulations [PDF]

Neurology, 2018
A 16-year-old boy with recurrent transient visual loss had bilateral papilledema. MRI revealed giant arachnoid granulations (GAG) in both transverse sinuses and signs of intracranial hypertension (figure). CSF opening pressure was 420 mm H2O. After depletive lumbar puncture, the size of GAG decreased and sinus lumen stenosis resolved (figure ...

Anatomical Study of Arachnoid Granulation in Superior Sagittal Sinus Correlated to Growth Patterns of Meningiomas

Frontiers in Oncology, 2022
Meningiomas in the parasagittal region were formed by arachnoidal cells disseminated among arachnoid granulations. The purpose of this study was to characterize the morphology of chordae willisii, and AGs found in the superior sagittal sinus.

Lymphatic clearance of the brain: perivascular, paravascular and significance for neurodegenerative diseases [PDF]

, 2016
The lymphatic clearance pathways of the brain are different compared to the other organs of the body and have been the subject of heated debates. Drainage of brain extracellular fluids, particularly interstitial fluid (ISF) and cerebrospinal fluid (CSF),

Intracranial pressure elevation alters CSF clearance pathways

Fluids and Barriers of the CNS, 2020
Background Infusion testing is a common procedure to determine whether shunting will be beneficial in patients with normal pressure hydrocephalus. The method has a well-developed theoretical foundation and corresponding mathematical models that describe ...
