The Chiari I malformation (CM-I) is a developmental alteration of the posterior cranial fossa (PCF), radiographically defined as the descent of the cerebellar tonsils = 5 mm below the foramen magnum (FM) inside the cervical canal. Headache is the most frequent symptom associated with CM-I. The association of CM-I and neurological symptoms configures with Chiari syndrome. A rare symptom associated with Chiari syndrome is intracranial hypertension syndrome with cephalea and papilloedema-the typical findings of pseudotumor cerebri (PTC)...

INTRODUCTION: The goal of this study was to evaluate the utility of orbital ultrasonography and magnetic resonance imaging in the diagnosis of idiopathic intracranial hypertension (IIH). METHOD: We reviewed the medical records of patients referred to our department for suspected IIH. RESULTS: Seven children were diagnosed with IIH. Nine children revealed pseudopapilledema by optic coherence tomography and/or orbital ultrasonography. When the axial sequences were reexamined, patients with papilledema had optic nerve sheath (ONS) enlargement (6...

Posterior reversible encephalopathy syndrome (PRES) is thought to result from endothelial dysfunction and breakdown of the blood-brain barrier with subsequent vasogenic edema. Abrupt hypertension has been identified as one of its risk factors. We present a rare case of PRES in the anterior circulation with sudden onset of left hemiparesis and rapid neurological deterioration on the basis of hypertensive crisis. Due to refractory intracranial hypertension, the patient required emergent right decompressive craniectomy...

OBJECTIVES/HYPOTHESIS: Spontaneous cerebrospinal fluid (CSF) leaks are associated with increased intracranial pressure (ICP) and considered a manifestation of idiopathic intracranial hypertension. Although postoperative acetazolamide and placement of CSF shunt systems are considered valuable interventions for elevated ICP, the impact on recurrence rate remains unclear. The objective of this study was to systematically review evidence from reported literature to evaluate whether postoperative ICP management reduces recurrence rates after primary endoscopic repair...

Measurement of intracranial pressure (ICP) can be invaluable in the management of critically ill patients. Cerebrospinal fluid (CSF) is produced by the choroid plexus in the brain ventricles (a set of communicating chambers), after which it circulates through the different ventricles and exits into the subarachnoid space (SAS) around the brain, where it is reabsorbed into the venous system. If the fluid does not drain out of the brain or get reabsorbed, the ICP increases, which may lead to brain damage or death...

REVIEW
M-B Rougier
This article will review the current standard of care in the diagnosis and management of bilateral optic disc edema. Two emergent conditions must be considered first: secondary intracranial hypertension (cerebral tumor, cerebral thrombophlebitis…) and arteritic ischemic optic neuropathy (or giant cell arteritis). Having ruled out these two diagnoses, the management follows various steps in order to: (i) rule out pseudo-edema, and (ii) determine the underlying cause of the edema: papilledema, non-arteritic ischemic optic neuropathy or papillitis...

BACKGROUND: Intracranial pseudoaneurysms are rare vascular defects of arterial walls that are classically the result of traumatic injury, iatrogenic causes, or infection. Idiopathic pseudoaneurysms are seen even less frequently and are often related to atherosclerosis. Pseudoaneurysms are most commonly found along the distal wall of the internal carotid artery, however, can occur at any location in the cerebrovascular circulation. Treatment of these arterial defects is often challenging due to their frail nature...

REVIEW
Mary Angela O'Neal
Headaches are a common neurological complaint during pregnancy and the postpartum period. Most are primary and benign, but there are also several secondary headaches. This review uses a practical case-based approach to the evaluation and management of the most common headaches referred for neurological consultation: primary headaches such as migraine as well as the presentation and management of some of the secondary headaches complicating pregnancy and the puerperium. These include: idiopathic intracranial hypertension, eclampsia, reversible cerebral vasoconstriction syndrome, cerebral venous thrombosis, pituitary apoplexy and postdural puncture headache...

BACKGROUND: Spontaneous cerebrospinal fluid (CSF) leaks are largely attributed to idiopathic intracranial hypertension and typically present as skull base defects with or without prolapse of intracranial contents. However, in our practice, we have encountered a distinct type of spontaneous CSF leak that presents in a different manner. OBJECTIVE: To discuss a newly-classified, difficult to treat, subset of spontaneous CSF leaks that present as excavation of the bone of the skull base in a tunnel- or canal-like fashion by a meningocele or meningoencephalocele instead of as a localized area of bony dehiscence...

OBJECTIVE: The diagnosis and management of patients with idiopathic intracranial hypertension (IIH) frequently relies on lumbar puncture to ascertain intracranial pressures. However, pressures derived this way may be spurious due to patient body habitus and behavior. We recently incorporated direct continuous intracranial pressure (ICP) monitoring into the work-up for IIH and review our experience and outcomes. METHODS: Through billing records, we identified all patients during a 3-year period who had a diagnosis of idiopathic intracranial hypertension and who underwent ICP monitoring prior to shunt placement or revision...

BACKGROUND: This study was aimed to determine risk factors for the recurrence of an intracranial saccular aneurysm (ISA) following endovascular treatment. The findings will help medical professionals to identify patients having a high risk of ISA recurrence and assist them in developing appropriate follow-up plans. RESULTS: During the follow-up period, 12.6% of the patients (83/658) experienced recurrent ISAs. An analysis of related factors, including gender, age, hypertension, diabetes mellitus, smoking, tumor size, width of the aneurysm neck, the presence or absence of a rupture, the volume embolization ratio (VER), the application or nonapplication of a stent, and follow-up time, revealed that a tumor size > 10 mm in diameter, wide-necked aneurysms, an anterior communicating or middle cerebral artery aneurysm, an aneurysm rupture, a VER < 20%, the absence of stent assistance, and follow-up time were high-risk factors for the recurrence of ISAs...

BACKGROUND: The conventional treatment for idiopathic intracranial hypertension involves weight loss, steroids, diuretics, and/or serial lumbar punctures; however, if the symptoms persist or worsen, surgical intervention is recommended. Surgical options include cerebrospinal fluid diversion procedures, such as ventriculoperitoneal and lumboperitoneal shunts, and optic nerve decompression with nerve sheath fenestration. The latter can be carried out using an endoscopic approach, but the outcomes of this technique have not been firmly established...

INTRODUCTION: Venous outflow obstruction has been implicated in the pathophysiology of a subset of patients with idiopathic intracranial hypertension (IIH), and venous sinus stenting (VSS) has emerged as an effective treatment. However, the effect of anesthesia on venous sinus pressure measurements is unpredictable. A more thorough understanding of the effect of the level of anesthesia on intracranial venous pressures might help to better define patients who might benefit most from stent placement...

OBJECTIVE Obstructive sleep apnea (OSA) is associated with the progression of abdominal and thoracic aortic aneurysms. However, the role of OSA in the overall outcome of intracranial aneurysms (IAs) has not yet been established. Authors of this report investigated the role of OSA in the overall outcome of IAs. METHODS Radiological and clinical data on patients (from 2010 through 2015) with confirmed IA were retrospectively reviewed. Significant differences between the OSA and non-OSA groups were determined using a chi-square test...
