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...

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...

Systemic juvenile idiopathic arthritis (SJIA) is one of the most severe forms of arthritis that affects children younger than 16 years of age at onset. SJIA often requires corticosteroids to control the inflammation. However, long-term corticosteroid use may have adverse effects, including intracranial hypertension (IH). Biologic therapies have been used as corticosteroid sparing agents. We report the first case of a child with steroid-dependent SJIA treated with tocilizumab, an IL-6 receptor monoclonal antibody, who developed fulminant IH, bilateral papilloedema and vision loss when oral prednisone was weaned from 2 to 1 mg per day...

This report is of two cases of asymmetrical papilloedema in patients with asymmetrical intraocular pressures (IOPs). The first patient presented with headaches, transient visual obscurations (TVOs), and elevated IOPs, and was found to have increased intracranial pressure caused by a torcula meningioma. He developed papilloedema after his IOPs were pharmacologically lowered; the papilloedema resolved after the IOP became elevated again after stopping his glaucoma drops, and then again returned as the IOP reduced when the drops were restarted...

A wide range of pathologies can cause papilloedema. Vestibular schwannoma is a benign and slow-growing tumour that causes symptoms and findings on ophthalmic examination when the diagnostic is delayed. The authors report a case of a 64-year-old male who presented with bilateral disc oedema secondary to a vestibular schwannoma grade 4. Obstructive hydrocephalus was not evident. The authors suggest that cerebrospinal fluid protein may have a role in the formation of optic disc oedema. A right suboccipital craniectomy was performed to remove the tumour, leading to secondary facial palsy...

This is a 25-year observational retrospective review of 372 consecutive participants with optic disc drusen or resolved papilloedema from idiopathic intracranial hypertension. The prevalence of optic disc drusen at 19% among eyes with resolved papilloedema was approximately 10 times higher and significantly increased (p < 0.001) as compared with the occurrence in the general population. Eyes with both resolved papilloedema and optic disc drusen had similar visual acuity and visual field outcome as compared with resolved papilloedema alone...

Papilloedema is a key clinical finding in the diagnosis of idiopathic intracranial hypertension (IIH). However, newly proposed criteria allow diagnosis without papilloedema only if certain neuroimaging features are present. It is currently unclear if these findings persist upon resolution of papilloedema and IIH. A retrospective chart review identified three groups of patients (six per group) who had received orbital imaging within 4 weeks of fundoscopic examination: (1) IIH patients without active papilloedema, (2) IIH patients with active papilloedema, and (3) patients with no history of IIH or papilloedema...
