Background: The primary role of brain imaging in idiopathic intracranial hypertension (IIH) is
to exclude other pathologies causing intracranial hypertension. However, subtle radiologic …

Objective To systematically review the potential value of MRI signs in the assessment of
intracranial hypertension (IIH). Methods MEDLINE and Embase were systematically …

Importance The magnetic resonance imaging (MRI) criteria currently used to diagnose
idiopathic intracranial hypertension (IIH) are based on expert opinion and have limited …

BACKGROUND AND PURPOSE: Following long-term spaceflight, a subset of the National
Aeronautics and Space Administration astronauts present with visual impairment and …

A skull base cerebrospinal (CSF) leak or fistula is an abnormal communication of the sterile
subarachnoid space with the sinonasal or tympanomastoid cavities, and presents clinically …

OBJECTIVE Chiari malformation type 1 (CM-1) and spontaneous intracranial hypotension
(SIH) are causes of headache in which cerebellar tonsillar ectopia (TE) may be present. An …

Background: We propose that the appearance of a ptosis of the cerebellar tonsils and
syringomyelia is linked to its own hemohydrodynamic mechanisms. We aimed to quantify …

Cerebrospinal fluid (CSF) leaks are extracranial egress of CSF into the adjacent paranasal
sinus or tympanomastoid cavity due to an osteodural defect involving skull base. It can be …

Magnetic resonance imaging (MRI) signs of elevated intracranial pressure and idiopathic
intracranial hypertension have been well characterized in adults but not in children. The …

OBJECTIVE Several lines of evidence suggest common pathophysiological mechanisms in
Chiari malformation Type I (CMI) and idiopathic intracranial hypertension (IIH). It has been …
