We report a case of a left frontal lobe meningioma presenting in a woman with proteinuric preeclampsia in her first term pregnancy. The patient had a background of antepartum migraines that resolved in the second trimester of pregnancy. Postpartum, she required urgent surgery and sustained convulsions after surgery. She had no residual disease and has had another successful pregnancy. This case highlights the importance of cerebral imaging in the context of an atypical clinical course of preeclampsia. Although headaches are common in pregnancy and usually benign, other, more serious, diagnoses should be considered with atypical headaches, a change in the nature of the headache, and headaches that persist despite appropriate treatment...

Chiari type 1 malformation (CM1) rarely causes papilloedema, which is indicative of high intracranial pressure with or without ventricular dilatation. Furthermore, concomitant brain parenchymal abnormalities have not been reported to date. In this paper, the authors report on a young woman of CM1-induced intracranial hypertension (ICH) with diffuse brain edema with a focus on venous sinus assessment, and discuss the surgical strategy. A 24-year-old woman presented to Nagoya University Hospital complaining of 4-year history of severe occipital headache and blurry vision with slowly progressive worsening...

INTRODUCTION: Effective treatments are lacking for idiopathic intracranial hypertension (IIH), a condition characterised by raised intracranial pressure (ICP) and papilloedema, and found primarily in obese women. Weight loss and lowering body mass index (BMI) have been shown to lower ICP and improve symptoms in IIH; however, weight loss is typically not maintained, meaning IIH symptoms return. The Idiopathic Intracranial Hypertension Weight Trial (IIH:WT) will assess whether bariatric surgery is an effective long-term treatment for patients with IIH with a BMI over 35 kg/m(2)...

Though not discussed in the medical literature or considered in clinical practice, there are similarities between chronic fatigue syndrome and idiopathic intracranial hypertension (IIH) which ought to encourage exploration of a link between them. The cardinal symptoms of each - fatigue and headache - are common in the other and their multiple other symptoms are frequently seen in both. The single discriminating factor is raised intracranial pressure, evidenced in IIH usually by the sign of papilloedema, regarded as responsible for the visual symptoms which can lead to blindness...

Schwannomas are nerve sheath tumours that originate in Schwann cells. They are usually solitary and sporadic and manifest on peripheral, spinal or cranial nerves. Intracranial schwannomas tend to manifest on the eighth cranial nerve, particularly in patients with neurofibromatosis type2. Anterior skull-base schwannomas represent less than 1% of all intracranial schwannomas. They are more frequent in young people and are typically benign. These tumours represent a diagnostic challenge due to their rarity and difficult differential diagnosis, and numerous theories have been postulated concerning their origin and development...

BACKGROUND: Following high-profile cases, referrals for evaluation of 'suspicious optic discs' to eye clinics in the UK have sharply increased, asking ophthalmologists to reliably distinguish between true and pseudopapilloedema. Optic nerve sheath dilatation (ONSD) on ocular ultrasound (US) is considered a reliable sign of true papilloedema, but this test is not widely available. Recently, anterior bowing of Bruch's membrane (BM) and increased retinal nerve fibre layer thickness on optical coherence tomography (OCT) have emerged as indicators of intracranial hypertension, and OCT is widely available...

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)...

PURPOSE: The ventriculoperitoneal (VP) shunt has become the procedure of choice for treatment of idiopathic intracranial hypertension (IIH). We aimed to assess the efficacy of frameless stereotactic placement of VP shunts for the management of medically resistant IIH in children and to assess the role of gender and obesity in the aetiology of the condition. METHODS: This is a retrospective analysis of the case notes of 10 patients treated surgically at the University Hospital of Wales in Cardiff, from May 2006 to September 2012...

The authors describe an immunocompetent, 50-year-old man who complained of a daily transient blurring of his vision with bilateral papilloedema. His visual acuity was 20/20 OU, and the blind spot was enlarged bilaterally. There was intracranial hypertension, but imaging for systemic and brain tumours were negative. These findings suggested a diagnosis of the pseudotumor syndrome. However, MRI showed leptomeningeal enhancement, and acetazolamide successfully resolved his visual symptoms and papilloedema. Cytology and flow cytometry of the CSF led to the final diagnosis of primary leptomeningeal lymphoma (PLML)...

A 52-year-old man with a history of factor V Leiden thrombophilia, persistent headaches and papilloedema presented with worsening vision and confusion. MRI and MR angiography of the brain at the time of this presentation showed findings concerning for transverse sinus thrombosis and an associated dural arteriovenous fistula. Dural venous sinus thrombosis can lead to the formation of a dural arteriovenous fistula, which must be considered in the differential diagnosis for intracranial hypertension in patients with thrombophilia...

Correct differential diagnosis in cases of blurred optic disc margins is a challenging task for ophthalmologists. The reliable differentiation of pseudopapilloedema and true papilloedema has significant implications for proper patient management. Conditions that give rise to pseudopapilloedema include small crowded discs, tilted discs and optic nerve head drusen. Conditions that cause bilateral true swelling of the optic nerve head with initially good visual acuity include those that are secondary to raised intracranial pressure (optic disc edema, ODE)...

A previously fit and healthy 26-year-old lady with no significant medical history presented with a two-month history of headaches. The headaches were prolonged, generalised, and unusually severe for the patient. Examination revealed papilloedema. The patient's optic nerve sheath diameter was measured 3 mm posterior to the globe and found to be 7.5 mm. The patient subsequently had computed tomography scan of her brain that showed an optic nerve sheath diameter of 7.56 mm as measured 3 mm posterior to the globe...

A Caucasian female previously diagnosed with anorexia nervosa was referred by psychiatric services to the general medical team. She presented with dehydration, vomiting, weakness, a body mass index of 13 kg/m(2) and was treated with intravenous and enteral supplementation. During admission her vomiting worsened and she developed visual hallucinations and confabulation. Neurological examination demonstrated cerebellar signs and bilateral papilloedema on fundoscopy. Subsequent magnetic resonance imaging of the brain revealed a large fourth ventricular tumour causing obstructive hydrocephalus...

The role of the optic canal in the pathogenesis of papilloedema has been under scrutiny recently. Whether a larger canal precedes more severe papilloedema or is the result of bone remodelling from chronically raised pressure across a pressure gradient is not clear. The authors present the magnetic resonance imaging findings of a 29-year-old female with fulminant and untreated idiopathic intracranial hypertension. Imaging showed focal expansion and intrinsic signal changes of the intracanalicular optic nerve...

Retinal haemorrhages (RH) and subdural haematomas (SDH) are frequently seen in abusive head trauma (AHT). The aim of our study is to show that they are suggestive, but not pathognomonic for AHT. We performed an observational retrospective study on children, aged 1-18 months old, admitted to the Antwerp University Hospital with RH. History, physical examination, medical course, coagulation and metabolic tests, skeletal survey, head circumference, retinal findings, cerebral imaging, and evaluation reports by social services or civil/criminal courts were collected...

A 36-year-old woman, with history of cutaneous papilomatosis and thyroid carcinoma presented with headache, transitory visual blurring and nausea. Funduscopy showed papilloedema. MRI showed a tumour of the right cerebellar hemisphere with a striated, tigroid pattern, typical of Lhermitte-Duclos disease (LDD). Significant clinical and perimetric improvements were noted after surgery and the follow-up did not reveal recurrences of the tumour. LDD is an extremely rare differential diagnosis of posterior fossa tumours...

RANDOMIZED CONTROLLED TRIAL
Michael Wall, Matthew J Thurtell
BACKGROUND: The risk of optic disc haemorrhages on visual outcome in idiopathic intracranial hypertension (IIH) is unknown. We report the type and frequency of optic disc haemorrhages and other funduscopic abnormalities at baseline in the study eye of the 133 subjects enrolled in the Idiopathic Intracranial Hypertension Treatment Trial completing 6 months of follow-up. METHODS: We reviewed optic disc photographs to tabulate the frequency and type of optic disc haemorrhages, other funduscopic abnormalities and papilloedema grades of the study eye at baseline and analyse if their presence is associated with a poor visual outcome...
