Ann Clin Transl Neurol 2023; 10:1305-1313. [PMID: 37272913 PMCID: PMC10424652 DOI: 10.1002/acn3.51822] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 04/23/2023] [Accepted: 05/23/2023] [Indexed: 06/06/2023] Open
Abstract
OBJECTIVES To compare the long-term safety and efficacy of stenting in correcting cerebral venous sinus stenosis (CVSS) and internal jugular venous stenosis (IJVS). METHODS Patients confirmed with CVSS or IJVS by imaging were enrolled in this real-world study from 2014 through 2021. Clinical characteristics and long-term outcomes of these two diseases entities post-stenting were followed up and compared. RESULTS Three hundred and nineteen patients were enrolled in this study, with a mean age of 48.83 years and a BMI of 25.08 on average. In which, 144 patients underwent stenting, the stenotic segments were corrected and the venous blood flow was restored immediately post-stenting. At 6.15 ± 1.67 days follow-up, significant improvement was observed in headache, tinnitus, insomnia, ICP, and mean pressure gradient in both groups (all p < 0.05). At 30.53 ± 4.41 months follow-up post-stenting, the headache, tinnitus, visual loss, papilledema, and insomnia were attenuated remarkably or even completely disappeared. The Frisen papilledema grade scores declined from 2 (0-4) to 1 (0-3) in IJVS group and from 4 (1-5) to 1 (0-4) in CVSS group compared to the baseline. One hundred and twenty-seven out of the 144 patients (95.5%) maintained sufficient blood flow verified by followed up computed tomographic venography or contrast-enhanced magnetic resonance angiography. Adverse events related to stenting included three cases of intraluminal restenosis and three cases of in-stent thrombosis, no intracranial hemorrhage, venous thromboembolisms, stent-adjacent stenosis, and stent displacement occurred. INTERPRETATION Using stents to correct IH and related neurological issues has shown to be a safe and effective approach for both IJVS and CVSS.

Bai C, Chen Z, Wu X, Ilagan R, Ding Y, Ji X, Meng R. Safety and efficacy comparison between OACs plus single antiplatelet and dual antiplatelet therapy in patients with cerebral venous sinus stenosis poststenting. BMC Neurol 2022; 22:209. [PMID: 35668360 PMCID: PMC9169277 DOI: 10.1186/s12883-022-02731-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 05/26/2022] [Indexed: 11/15/2022] Open
Abstract
Background and purpose The present strategies regarding poststent management for cerebral venous sinus stenosis (CVSS) are inconsistent. Herein, we compared the safety and efficacy of oral anticoagulants (OACs) plus single antiplatelet therapy and dual antiplatelet therapy for CVSS poststenting. Methods A real-world observational study conducted from January 2009 through October 2019 enrolled patients who were diagnosed with CVSS and received stenting. Patients were divided into two groups according to the management they received poststenting. Group 1: OACs plus a single antiplatelet agent (clopidogrel 75 mg or aspirin 100 mg) and Group 2: dual antiplatelet therapy (clopidogrel 75 mg plus aspirin 100 mg). The safety (such as major or minor bleeding or venous thrombosis) and efficacy (the incidences of cerebral venous sinus restenosis, intrastent thrombosis, or stent displacement) of the two groups were compared. Results There were a total of 110 eligible patients in the final analysis, including 79 females and 31 males with a mean age of 43.42 ± 13.23 years. No major bleeding or venous thrombosis occurred in either of the two groups. Two minor bleeding events occurred in group 2 (one with subcutaneous bleeding points in both lower limbs, another with submucosal bleeding in the mouth), whereas no bleeding events occurred in Group 1. In addition, at the 1-year follow-up, one case of intraluminal restenosis and two cases of in-stent thrombi occurred in Group 2, while none occurred in Group 1. Neither stenosis at stent-adjacent segments nor stent migration was detected in either group during the 1-year following stent placement. Conclusion OACs plus single antiplatelet therapy and dual antiplatelet therapy alone are both safe and efficacious management strategies after CVSS stent placement. The former may have more advantages than the latter for inhibiting intrastent thrombosis. However, further research by larger, multicenter clinical trials is needed.

Abstract
CME: Idiopathic Intracranial Hypertension Abstract. Idiopathic intracranial hypertension is a pressure-induced secondary headache disorder and optic neuropathy. It primarily affects obese women of childbearing age and poses an interdisciplinary challenge both diagnostically and therapeutically. The most common symptom of this disorder are headaches frequently accompanied by photo- and/or phonophobia, whose semiology often resembles that of migraine, followed by transient visual obscurations and pulsatile tinnitus. While protection of visual acuity and visual fields are of first therapeutical priority, adequate headache treatment also plays a key role. In the majority of cases, conservative treatment including weight loss and pharmacological therapy is sufficient. In case of a fulminant disease course or loss of visual function, interventional strategies can be applied additionally. Headache treatment is guided by the predominant semiology.

Different patterns of white matter lesions among patent foramen ovale, atherosclerotic cerebral small vessel disease and cerebral venous thrombosis. J Thromb Thrombolysis 2022; 53:911-925.

Abstract
None of studies are available on the predictive ability of white matter lesions (WMLs) among patent foramen ovale (PFO), atherosclerotic cerebral small vessel disease (aCSVD) and cerebral venous thrombosis (CVT). Herein, we aimed to uncover the difference of the WML patterns among the three disease entities in a real-world setting to provide clinical references for predicting probable WML etiologies. We retrospectively reviewed data from consecutive patients with imaging-confirmed PFO, aCSVD, or CVT enrolled from 2014 through 2020. WMLs presented on fluid-attenuated inversion recovery (FLAIR) maps were compared among the three groups based on visual evaluation, Fazekas and modified Scheltens scales. Propensity score matching (PSM) was implemented to correct age and hypertension differences among groups. A total of 401 patients were entered into final analysis, including PFO (n = 112, 46.5 ± 12.8 years), aCSVD (n = 177, 61.6 ± 11.8 years) and CVT (n = 112, 37.4 ± 11.4 years) groups. In this study, WMLs occurred in all of the involved patients in the three groups (100%), which were independent to age, symptom onset and disease durations. On visual evaluation, PFO-WMLs were multiple spots distributed asymmetrically around bilateral subcortex and peri-ventricles. aCSVD-WMLs were dots or sheets distributed symmetrically in subcortex and peri-ventricles, and often coexisted with lacunar infarctions. CVT-WMLs were cloud-like around bilateral peri-ventricles, and enabled to attenuate after recanalization. Fazekas and modified Scheltens scores of PFO-WML vs. aCSVD-WML were significantly different even after being matched by 1:2 PSM (all p < 0.05), meaning that the WML burden in aCSVD was considerably heavier than that in PFO. WML patterns induced by PFO, aCSVD and CVT were obviously different, and were therefore of great clinical significance to preliminarily predict and differentiate the three diseases entities.

Abstract
AIMS To explore the effect of nonthrombotic internal jugular venous stenosis (IJVS) exerted on cerebral venous thrombosis (CVT). METHODS Patients with imaging confirmed CVT were enrolled into this real-world case-control study consecutively from January 2018 through April 2021, and were divided into CVT and IJVS-CVT groups, according to whether or not with non-thrombotic IJVS. Chi-square and logistic regression models were utilized for between-group comparison of thrombotic factors. RESULTS A total of 199 eligible patients entered into final analysis, including 92 cases of CVT and 107 cases of IJVS-CVT. Chi-square revealed that thrombophilic conditions were found in majority of CVT, while only minority in the IJVS-CVT group (83.7% vs. 20.6%, p < 0.001). Multivariate logistic regression indicated that most identified thrombophilia were negatively related to IJVS-CVT (all p < 0.05), including oral contraceptive use (β = -1.38), hyperhomocysteinemia (β = -1.58), hematology (β = -2.05), protein C/S deficiency (β = -2.28), connective tissue disease (β = -1.18) and infection (β = -2.77). All recruited patients underwent standard anticoagulation, 10 cases in IJVS-CVT group also received jugular angioplasty for IJVS correction. Most participants obtained alleviations during 1-year follow-up. However, both clinical and imaging outcomes in IJVS-CVT group were not as good as those in CVT group (both p < 0.05). Moreover, 8 cases with CVT and 7 cases with IJVS-CVT were rehospitalized for CVT recurrences and underwent customized treatment. CONCLUSION Nonthrombotic IJVS may be one of the risk factors of CVT. Anticoagulation might need to be suggested for IJVS patients.

Abstract
In keeping with its status as one of the major causes of disability and mortality worldwide, brain damage induced by cerebral arterial disease has been the subject of several decades of scientific investigation, which has resulted in a vastly improved understanding of its pathogenesis. Brain injury mediated by venous etiologies, however, such as cerebral, jugular, and vertebral venous outflow disturbance, have been largely ignored by clinicians. Unfortunately, this inattention is not proportional to the severity of cerebral venous diseases, as the impact they exact on the quality of life of affected patients may be no less than that of arterial diseases. This is evident in disease sequelae such as cerebral venous thrombosis (CVT)-mediated visual impairment, epilepsy, and intracranial hypertension; and the long-term unbearable head noise, tinnitus, headache, dizziness, sleeping disorder, and even severe intracranial hypertension induced by non-thrombotic cerebral venous sinus (CVS) stenosis and/or internal jugular venous (IJV) stenosis. In addition, the vertebral venous system (VVS), a large volume, valveless vascular network that stretches from the brain to the pelvis, provides a conduit for diffuse transmission of tumors, infections, or emboli, with potentially devastating clinical consequences. Moreover, the lack of specific features and focal neurologic signs seen with arterial etiologies render cerebral venous disease prone to both to misdiagnoses and missed diagnoses. It is therefore imperative that awareness be raised, and that as comprehensive an understanding as possible of these issues be cultivated. In this review, we attempt to facilitate these goals by systematically summarizing recent advances in the diagnosis and treatment of these entities, including CVT, CVS stenosis, and IJV stenosis, with the aim of providing a valid, practical reference for clinicians.

Abstract
Background Cerebral venous sinus (CVS) stenting has been widely applied for correcting CVS stenosis. However, there are still some potential complications. The purpose of this study is to investigate the impact of perioperative management on avoiding complications of CVS stenting. Methods Patients confirmed as CVS stenosis were enrolled from January 2014 through November 2019. All CVS stenosis were corrected by stenting when the trans-stenotic mean pressure gradient (MPG) was up to or over 8 mmHg. Patients were divided into perioperative management group and control group. Patients in the former group underwent transiently mannitol 250 mL intravenous infusion immediately prior to stenting besides routine ICP control. While patients in control group underwent the same routine treatment as in the perioperative management group. The clinical symptoms, intracranial pressure (ICP), and MPG of the patients were compared before and after stenting. In addition, the complications between the two groups were compared. Results A total of 81 eligible patients were finally enrolled in this study, including 64 females and 17 males, mean aged 45.35±13.83 years. After stenting, the stenotic CVS restored normal blood flow and MPG decreased significantly [10.0 (8.0–15.0) vs. 0.0 (0.0–0.7) mmHg, P<0.001]. Headache, tinnitus, visual impairment, visual loss, Frisén papilledema grade (FPG), and ICP were ameliorated immediately (P<0.001) in the majority of patients in the two groups. However, the incidence of intracranial hemorrhage was higher in control group (11.4% vs. 0.0%, P=0.031). Conclusions A transiently strict preoperative ICP control by mannitol may inhibit CVS stenting-related hemorrhage, which makes the stenting safer and more effective on correcting the CVS stenosis.

Abstract
BACKGROUND A pressure wire offers a dynamic tool to assist in the measurement of the pressure gradient and assessment of the functional significance of stenosis. The author presents a patient with idiopathic intracranial hypertension who was diagnosed with cerebral venous sinus stenosis (CVSS). Venography accompanied by pressure measurement was used to guide the stent placement for CVSS. CASE DESCRIPTION A 27-year-old woman was referred to our hospital with a chief complaint of headache and neckache lasting for 7 weeks, with an 8-day history of binocular diplopia and blurred vision. Magnetic resonance venography and digital subtraction angiography showed a filling defect in the right transverse sinus. A pressure wire was used before endovascular treatment and showed that the pressure gradient was 10 mm Hg, which meets the surgical indication. After a stent was placed, no pressure gradient was recorded by the pressure wire. CONCLUSIONS This is the first report about using a pressure wire for CVSS. The finding suggests that use of a pressure wire can be a new approach in the diagnosis and treatment of CVSS.

Abstract
Internal jugular vein (IJV) stenosis and cerebral venous sinus (CVS) stenosis belong to cerebral venous outflow insufficiency. This study aimed to analyze the similarities and differences between IJV stenosis and CVS stenosis. Patients with either IJV stenosis or CVS stenosis confirmed by contrast-enhanced magnetic resonance venography between October 2017 and July 2018 were enrolled in this retrospective study. The similarities and differences between IJV stenosis and CVS stenosis on the aspects of clinical and imaging features were compared. A total of 82 eligible patients entered into the final analysis. The similarities of the two subsets of cerebral venous outflow insufficiency mainly included headache, head noises or tinnitus, visual disorders, and sleeping disorders, as well as cloud-like white matter hyperintensity in T2WI and FLAIR sequences of MRI. However, there were differences in between, the ratio of patients with higher intracranial pressure (ICP) was common in CVS stenosis (p < 0.001). Namely, higher ratios of papilledema (p = 0.001) and visual damage (p = 0.029), as well as poor Frisen papilledema grade scores were more commonly observed in CVS stenosis (p = 0.004), while abnormal collateral-vessels appeared more frequently in IJV stenosis (100.00%) than CVS stenosis (28.57%). Continuous head noises, tinnitus and cloud-like white matter hyperintensity in MRI are the features of both IJV stenosis and CVS stenosis. Whereas, severe headache, visual damage, papilledema, and intracranial hypertension (IH) were more common in CVS stenosis, and the appearance of collateral-vessels is a key feature of IJV stenosis.

Abstract
This study determines the reproducibility of magnetic resonance elastography (MRE) derived brain stiffness in normal volunteers and compares it against pseudotumor patients before and after lumbar puncture (LP). MRE was performed on 10 normal volunteers for reproducibility and 14 pseudotumor patients before and after LP. During LP, opening and closing cerebrospinal fluid (CSF) pressures were recorded before and after removal of CSF and correlated to brain stiffness. Stiffness reproducibility was observed (r > 0.78; p < 0.008). Whole brain opening LP stiffness was significantly (p = 0.04) higher than normals, but no significant difference (p = 0.11) in closing LP measurements. No significant correlation was observed between opening and closing pressure and brain stiffness.

Inflammatory gene expression signatures in idiopathic intracranial hypertension: possible implications in microgravity-induced ICP elevation. NPJ Microgravity 2018; 4:1. [PMID: 29354685 PMCID: PMC5764966 DOI: 10.1038/s41526-017-0036-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2017] [Revised: 11/06/2017] [Accepted: 12/13/2017] [Indexed: 11/23/2022] Open
Abstract
The visual impairment and intracranial pressure (VIIP) syndrome is a neuro–ophthalmologic condition described in astronauts returning from long duration space missions. Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is characterized by a chronic elevation of intracranial pressure (ICP) in the absence of an intracranial mass lesion. Because VIIP and IIH share some neurologic and ophthalmologic manifestations, the latter might be used as a model to study some of the processes underlying VIIP. This work constitutes a preliminary investigation of the molecular pathways associated with the elevation of ICP in IIH. Gene expression signatures were obtained from exosomes collected from CSF and plasma in patients with possible signs of IIH. The gene expression targets focused on inflammatory genes and miRNAs. The results suggest that inflammatory cytokine-driven processes and immune cell migration are activated when ICP is elevated in IIH patients, either as a cause or effect of the ICP increase. Several miRNAs appear to be involved in this response, among which miR-9 and miR-16 are upregulated in CSF and plasma of higher ICP subjects. This study provides evidence in support of neurophysiological alterations and neuro-immunomodulation in this condition. If similar changes are seen in astronauts manifesting with the VIIP syndrome, an underlying pathophysiological basis may be discovered. People with elevated pressure inside their skulls show signs of inflammation that could be relevant for astronauts on long-duration missions. To better understand the biology of spaceflight-induced visual impairment—a common problem for astronauts that is thought to arise from pressure building up around the brain in microgravity—a team led by Susana Zanello from the NASA Johnson Space Center in Houston, Texas, USA, examined the spinal fluid and blood of individuals with idiopathic intracranial hypertension, a neurologic condition that shares some features with the mysterious syndrome that impairs astronauts’ sight vision. The researchers characterized the RNA contained within tiny secreted particles, known as exosomes, in the patient samples. The expression of several genes and regulatory microRNAs linked to pro-inflammatory immune responses were changed. The authors surmise that similar immune changes could underpin the eyesight syndrome plaguing astronauts.

Abstract
BACKGROUND Pseudotumor cerebri (PTC), also known as idiopathic intracranial hypertension (IIH), is a condition associated with increased intracranial pressure (ICP) in the absence of radiographic findings such as mass lesions or cerebral edema. CASE DESCRIPTION We describe a case of progressive headache and visual disturbances attributed to PTC that resulted from subacute superior sagittal sinus (SSS) stenosis by a metastatic tumor. CONCLUSIONS Venous outflow obstruction often presents with an acute symptomatology including infarcts, hemorrhages, and seizures, but only rarely does it cause the progressive development of raised ICP. The sinister presentation of our patient's pathology stemmed from local mass effect caused by a tumor that has hitherto not been reported to cause intracranial hypertension (IH) and was best elucidated using magnetic resonance venography (MRV).

Optical coherence tomography for the diagnosis and monitoring of idiopathic intracranial hypertension. J Neurol 2017; 264:1370-1380.

Abstract
The objectives of the study were to investigate the value of optical coherence tomography in detecting papilledema in patients with idiopathic intracranial hypertension (IIH), a disease which is difficult to monitor and which can lead to permanent visual deficits; to analyze retinal changes over time. In this non-interventional case-control study, spectral-domain optical coherence tomography (SD-OCT) was used to analyze the retinal and optic nerve head (ONH) morphology of 21 patients with IIH and 27 age- and sex-matched healthy controls over time. We analyzed the ONH volume using a custom-made algorithm and employed semi-automated segmentation of macular volume scans to assess the macular retinal nerve fiber layer (RNFL) and ganglion cell layer and inner plexiform layer complex as well as the total macular volume. In IIH patients, the ONH volume was increased and correlated with cerebrospinal fluid (CSF) pressure. The ONH volume decreased after the initiation of treatment with acetazolamide. The macular RNFL volume decreased by 5% in 3.5 months, and a stepwise multivariate regression analysis identified CSF pressure as the main influence on macular RNFL volume at diagnosis. The only factor predicting macular RNFL volume loss over time was ONH volume. SD-OCT can non-invasively monitor changes in retinal and ONH morphology in patients with IIH. Increased ONH volume leads to retinal atrophy in the form of macular RNFL volume loss, presumably due to mechanic jamming of the optic nerve at the disc and subsequent axonal loss.

Abstract
Background and purpose Headache constitutes the most common symptom of cerebral venous sinus thrombosis (CVST), but its pathophysiology is unclear. We sought to investigate the potential mechanism for headache genesis in patients with CVST based on its imaging correlates. Methods A subgroup of CVST patients having headache as the predominant symptom without significant parenchymal lesion were retrospectively analysed for imaging features of vascular congestion (VC), in addition to cortical venous (CVT) and dural sinus thrombosis (DST) on magnetic resonance imaging. Headache and imaging patterns were classified into lateralized and nonlateralized phenotypes and their correlation was sought. Results Among 41 patients included, 28 had lateralized headache (LH group; 15 males; mean age 32.25 ± 9.19 years) while 13 had nonlateralized headache (non-LH group; six males; mean age 27.15 ± 8.65 years). Headache characteristics in both the groups were quite similar. Imaging showed VC in 39 of 41 and CVT among 35 of 41 patients, which were lateralized in 23 of 39 and 18 of 35 patients, respectively. Nearly all lateralized imaging patterns (21 of 23 for VC and 17 of 18 for CVT) occurred in the LH group and ipsilateral to (concordant) headache, while the non-LH group showed lateralized VC and CVT in only two and one patient respectively. Sinus thrombosis was lateralized in both groups irrespective of headache laterality. Whole cohort headache-imaging laterality (including patients with nonlateralized headache and nonlateralized imaging) concordance was 31 of 39, 24 of 35 and 18 of 41 for vascular congestion, cortical vein thrombosis and dural sinus thrombosis respectively. Conclusion Co-localization of VC and CVT with overlying headache might provide a possible explanation of headache and its laterality in patients with CVST.

Abstract
Summary
According to the definition, idiopathic intracranial hypertension (IIH) is a pathological state characterized by an increase in intracranial pressure; however, there are no obvious intracranial pathological processes. The pathophysiology of this disorder is not clear, although there are many reports related to it.
We present an overview of possible etiopathogenetic mechanisms, clinical presentations and therapeutic interventions from a series of patients hospitalized with the clinical picture and final diagnosis of idiopathic intracranial hypertension (IIH). All data were collected from the moment of IIH diagnosis as well as three months later.
The obtained data showed that IIH is a disease that primarily affects obese women in early and midlife. The positive correlation between values of cerebrospinal fluid pressure and body mass index was observed. The disorders of sexual hormones were identified as a possible etiology for IIH female patients. Headache, papilloedema, decreased visual acuity, vertigo and cranial nerve palsy were identified as the most prevalent IIH clinical presentations. The existence of stenosis and hypoplasia of the sigmoid and transverse sinus were confirmed only in one third of IIH patients. Pharmacotherapy combined with weight loss was efficacious in a large number of patients. In this series, there were no short-term consequences of IIH.
The results suggest the importance of early and accurate looking for IIH in obese early and midlife women with any hormonal imbalances having a variety of neurological expression, mostly presented as headaches and visual disturbances. Early detection of IIH might influence the timely treatment and prevent far-reaching and severe clinical consequences.

Abstract
Lumbar puncture (LP) is a commonly performed procedure in diagnosis and management of neurological conditions. LP is generally safe, however there are a number of potentially serious complications, including epidural haematoma and cerebral herniation. The risks of these should be considered and minimised prior to undertaking LP. Our regional neuroscience centre provides an outpatient LP service for patients throughout southeast England. Referrals from distant hospitals meant there was frequently no access to important clinical information, including indication for LP, past medical history, or medication history until the day of the procedure, and no access to results of investigations such as coagulation profile, platelet count, or intracranial imaging. Furthermore, there was limited capacity or time available in the day ward to perform these tests prior to LP. As a result, patients were either having LPs cancelled on the day of the procedure, were delayed by several hours on the day of the procedure for investigations, or were subject to the risk of having the LP performed without the knowledge of these key safety indicators. To address this issue we implemented an LP safety checklist to be completed by referring neurologists, providing details of the patient's medical history and results of investigations performed locally. In doing this, we increased the proportion of patients with an available platelet count prior to LP from 25% to 89%, and available coagulation profile from 18% to 82%. In addition, we saw a qualitative increase in the confidence of junior doctors in the safety of the LP clinic, as measured by a survey taken before and after the implementation of this system. This simple intervention made a rapid and remarkable difference to the safety and efficiency of this outpatient LP clinic. We would encourage other units to adopt this approach to address similar problems in a variety of outpatient settings.

Abstract
INTRODUCTION Idiopathic intracranial hypertension (IIH) is a rare condition that is often managed conservatively. In patients with aggressive progression of the disease surgical options are considered. There are few data on the outcomes of these patients when surgically managed. We describe our experience of surgically managed IIH and the outcomes of these patients, in particular the surgical revision rate and interventions required for resolution of symptoms. METHODS A retrospective review of all patient files coded with benign intracranial hypertension, idiopathic intracranial hypertension or pseudotumour cerebri was undertaken. Files were searched with the date of diagnosis and the date these patients were referred for surgical intervention. The surgical interventions and complications were then documented and note was made of the number of inpatient admissions and days spent in hospital. RESULTS From 2000-2013, 79 patients were identified as patients with IIH that had required surgical intervention; 52 % required further surgical intervention. The average number of surgical interventions was 5.6. For patients requiring further intervention the average number of surgical interventions was 8.6. On average patients with IIH also spent 42 inpatient days in neurosurgical beds, whilst those patients who required further intervention spent 63 days on average in neurosurgical beds. The length of the average individual admission was longer for patients requiring repeated surgical interventions. CONCLUSION Based on our experience, patients that require surgical management of IIH frequently require further surgical interventions to control symptoms and manage complications of CSF diversion surgery. Those that require such further intervention on average will have six further operations and spend significantly longer in hospital. Lumboperitoneal (LP) shunting is an effective first line surgical intervention for 52 % of our patient cohort. This sub-group of patients therefore requires specialist neurosurgical input for this long-term and challenging pathological process.

Abstract
Acute visual symptom emergencies occur commonly and present a challenge to both clinical and radiologic facets. Although most patients with visual complaints routinely require clinical evaluation with direct ophthalmologic evaluation, imaging is rarely necessary. However, there are highly morbid conditions where the prompt recognition and management of an acute visual syndrome (AVS) requires an astute physician to probe further. Suspicious symptomatology including abrupt visual loss, diplopia, ophthalmoplegia, and proptosis/exophthalmos require further investigation with advanced imaging modalities such as magnetic resonance imaging and magnetic resonance angiography. This review will discuss a variety of AVSs including orbital apex syndrome, cavernous sinus thrombosis, cavernous carotid fistula, acute hypertensive encephalopathy (posterior reversible encephalopathy syndrome), optic neuritis, pituitary apoplexy including hemorrhage into an existing adenoma, and idiopathic intracranial hypertension. A discussion of each entity will focus on the clinical presentation, management and prognosis when necessary and finally, neuroimaging with emphasis on magnetic resonance imaging. The primary purpose of this review is to provide an organized approach to the differential diagnosis and typical imaging patterns for AVSs. We have provided a template for radiologists and specialists to assist in early intervention in order to decrease morbidity and provide value-based patient care through imaging.

Abstract
OBJECTIVE Unsuspected idiopathic intracranial hypertension (IIH) is found in a significant minority of patients attending clinics with named headache syndromes, if it is specifically sought out. Chronic fatigue syndrome is frequently associated with headache. Could the same be true of chronic fatigue? Moreover, there are striking similarities between the two conditions. Could they be related? Attempting to answer these questions, we describe the results of a change in clinical practice aimed at capturing patients with chronic fatigue who might have IIH. DESIGN Cross-sectional. SETTING Hospital outpatient and radiology departments. PARTICIPANTS Patients attending a specialist clinic with chronic fatigue syndrome and headache who had lumbar puncture to exclude raised intracranial pressure. MAIN OUTCOME MEASURES Intracranial pressure measured at lumbar puncture and the effect on headache of cerebrospinal fluid drainage. RESULTS Mean cerebrospinal fluid pressure was 19 cm H2O (range 12-41 cm H2O). Four patients fulfilled the criteria for IIH. Thirteen others did not have pressures high enough to diagnose IIH but still reported an improvement in headache after drainage of cerebrospinal fluid. Some patients also volunteered an improvement in other symptoms, including fatigue. No patient had any clinical signs of raised intracranial pressure. CONCLUSIONS An unknown, but possibly substantial, minority of patients with chronic fatigue syndrome may actually have IIH. An unknown, but much larger, proportion of patients with chronic fatigue syndrome do not have IIH by current criteria but respond to lumbar puncture in the same way as patients who do. This suggests that the two conditions may be related.

Abstract
BACKGROUND AND PURPOSE Idiopathic intracranial hypertension is a headache syndrome characterized by increased CSF pressure. Compression of the hypophysis and distension of the optic nerve sheath are reliable imaging signs. The purpose of the study was to validate, in patients with idiopathic intracranial hypertension, MR imaging-based volumetric measurements of the optic nerve sheath and hypophysis as an objective observation method for more accurate diagnosis and posttreatment follow-up. MATERIALS AND METHODS Twenty-three patients with idiopathic intracranial hypertension as well as age-, sex-, and body mass index-matched controls underwent volumetric measurements of the optic nerve, optic nerve sheath, and hypophysis on high-resolution T2-weighted MR images by using a 7-cm surface coil, followed by correlation with CSF opening pressures and clinical symptom scores of visual disturbances and headache. RESULTS Mean values of optic nerve sheath (341.86 ± 163.69 mm(3) versus 127.56 ± 53.17 mm(3), P < .001) and hypophysis volumes (554.59 ± 142.82 mm(3) versus 686.60 ± 137.84 mm(3), P < .05) differed significantly between healthy and diseased subjects. No significant differences between mean optic nerve volumes were observed. Receiver operating characteristic analysis showed optic nerve sheath volumes of >201.30 mm(3) (sensitivity, 86.96%; specificity, 91.30%) and hypophysis volumes of <611.21 mm(3) (sensitivity, 78.26%; specificity, 69.57%) to be indicative of idiopathic intracranial hypertension diagnosis. In patients with idiopathic intracranial hypertension, no correlations were found between optic nerve sheath and hypophysis volumes and CSF opening pressures or clinical scores of visual disturbances and headache. CONCLUSIONS Semiautomated volumetric measurement of optic nerve sheath and hypophysis has the potential to more accurately diagnose and follow patients with idiopathic intracranial hypertension.
