Renal Pelvis Opacification on Postmyelography Computed Tomography as an Indicator for Cerebrospinal Fluid Loss in Spontaneous Intracranial Hypotension
TLDR
Although the provenance of early renal opacification in SLEC (−) SIH patients remains unclear, the results suggest that it may be a surrogate for increased spinal CSF resorption via spinal arachnoid granulations and along spinal nerve sheaths occult to direct imaging.
Dual-Energy CT in Enhancing Subdural Effusions that Masquerade as Subdural Hematomas: Diagnosis with Virtual High-Monochromatic (190-keV) Images
TLDR
Dual-energy CT has a high sensitivity and specificity and has a potential to obviate follow-up studies, which can be mistaken as acute subdural hematomas on follow- up noncontrast head CTs.
The Glymphatic Pathway: Waste Removal from the CNS via Cerebrospinal Fluid Transport
TLDR
The general anatomy and physiology of CSF is discussed and reviewed from the perspective of the glymphatic pathway, a discovery which has greatly improved understanding of key factors that control removal of metabolic waste products from the central nervous system in health and disease and identifies an additional purpose for sleep.

The Optic Syrinx : Cavernous Degeneration of the Optic Nerve Demonstrated by lopamidol Optic
TLDR
This is the first report to describe syrinx formation of the optic nerves in vivo in two patients with non glaucomatous conditions affecting the optic nerve.
Large subdural effusions after angiography mimicking acute subdural hematoma.
TLDR
This is the first case of extensive contrast extravasation into the subdural space after percutaneous coronary intervention in the brain parenchyma after intra-arterial angiography.
Immediate CT findings following embolization of cerebral aneurysms: suggestion of blood–brain barrier or vascular permeability change
TLDR
After uneventful endovascular treatment of cerebral aneurysms, the immediate brain CT findings can reveal various patterns of abnormal contrast enhancement.
Fatal complications after myelography with meglumine diatrizoate
TLDR
RP-HPL-Chromatography confirmed high concentration of the contrast medium in CSF which must have induced refractory central nervous dysregulation and the lethal effects of the misapplication of this agent on the nervous system are discussed.
Iotrol, a new water-soluble non-ionic dimeric contrast medium for intrathecal use
TLDR
The low persistence of iotrol in the brain parenchyma is demonstrated on CT density profiles, compared with metrizamide and iopamidol.

The Surface Characteristics of Arachnoid Granulations: A Scanning Electron Microscopical Study
TLDR
The arachnoid granulations of six adult sheep were fixed by simultaneous subarachnoids and arterial perfusion with 3% glutaraldehyde in phosphate buffer and the following changes were seen in the apical areas of the granulations: the microvilli covering the endothelial cells decreased in number and size; the areas of apposition of adjacent endothelial Cells were more irregular.

TLDR
The results suggest that alterations in blood-brain barrier permeability following angiography are mediated by both hyperosmolality of the contrast medium and the chemotoxicity of the Contrast molecule.
