“…The detection of contrast enhancement has a smaller sensitivity due to the small dimension of the nerve head and could also be produced in some inflammatory lesions of the optic nerve [ 36 ]. In a comparison of neuroimaging findings in patients with idiopathic intracranial hypertension and others with cerebral venous thrombosis, optic nerve head protrusion was present only in patients with IIH, and none in the cerebral venous thrombosis group [ 37 ].…”

In this review, we provide an update on the pathogenesis, diagnosis, and management of adults with idiopathic intracranial hypertension (IIH) and implications of the cerebral venous system, highlighting the progress made during the past decade with regard to mechanisms of the venous outflow pathway and its connection with the cerebral glymphatic and lymphatic network in genesis of IIH. Early diagnosis and treatment are crucial for favorable visual outcomes and to avoid vision loss, but there is also a risk of overdiagnosis and misdiagnosis in many patients with IIH. We also present details about treatment of intracranial hypertension, which is possible in most cases with a combination of weight loss and drug treatments, but also in selected cases with surgical interventions such as optic nerve sheath fenestration, cerebral spinal fluid (CSF) diversion, or dural venous sinus stenting for some patients with cerebral venous sinus stenosis, after careful analysis of mechanisms of intracranial hypertension, patient clinical profile, and method risks.

“…MR images contrast enhancement allows one to see a symptom similar to empty delta sign symptom on CT in thrombotic sinus occlusion [76] when on T1WIagainst the background of contrast-enhanced sinus walls as a thrombus in the sinus lumen -looks much less intense. In addition, indirect signs of increased intracranial pressure can be considered as increased perioptic cerebrospinal fluid and optic nerve tortuosity [77].…”

The purpose of the narrative review is to search for confirmation or controversy of the hypothesis according to which venous ischemia developing in cerebral venous sinustrombosis is secondary as a result of mechanical narrowing of arterioles in the area of vasogenic edema. This review discusses the issues of multimodal radiological diagnosis of a rare disease of a non-hemorrhagic ischemic venous stroke based on expert opinion, current recommendations and our experience. As a result of the review no contradictions to this hypothesis have been found, and the most characteristic symptoms of CVT, secondary ischemia, intracranial venous congestion can be identified in the order of their probable clinical manifestation from patient complaints to the results of instrumental studies: headache, subacute development and course of the disease, papilledema optic disc, increase of central venous pressure, hypodensity of the ischemic foci and hyperdensity signs of sinus on CT, earlier development of vasogenic edema on diffusion MRI, symptoms of stop-contrast and filling defect thrombosed sinuses on contrast enhancement CTA or MRA, dilatation of venous regional collaterals, moderate hyperperfusion on CT-or MR-perfusion, elevated maximum blood flow velocity Rosenthal veins; Galen's vein and rectus sinus, decreased cerebrovascular reactivity index, increased peripheral resistance index on Transcranial Doppler, clot visualization on brachiocephalic veins ultrasound duplex scanning, decreasing of brachiocephalic vessels ultrasound index of arteriovenous ratio.

“…The underlying cause of idiopathic intracranial hypertension (IIH) is uncertain: it primarily affects obese women of reproductive age, is of increasing incidence and can lead to vision loss [136]. A diagnostic feature is the presence of increased peri-optic CSF determined by neuroimaging [137]. O'Reilly et al [138] examined the systemic and CSF androgen metabolome in patients with IIH and found a unique signature of androgen excess and provide evidence that this may affect CSF secretion.…”

This editorial highlights advances in brain barrier and brain fluid research published in 2019, as well as addressing current controversies and pressing needs. Topics include recent advances related to: the cerebral endothelium and the neurovascular unit; the choroid plexus, arachnoid membrane; cerebrospinal fluid and the glymphatic hypothesis; the impact of disease states on brain barriers and brain fluids; drug delivery to the brain; and translation of preclinical data to the clinic. This editorial also mourns the loss of two important figures in the field, Malcolm B. Segal and Edward G. Stopa.
