INTRODUCTION: Vitamin A and its metabolites (called retinoids) have been thought to play a role in the development of idiopathic intracranial hypertension (IIH). The IIH Treatment Trial (IIHTT) showed the efficacy of acetazolamide (ACZ) in improving visual field function, papilledema grade, quality of life and cerebrospinal fluid (CSF) pressure. We postulated that IIH patients would demonstrate elevated measures of vitamin A metabolites in the serum and CSF. METHODS: Comprehensive measures of serum vitamin A and its metabolites were obtained from 96 IIHTT subjects, randomly assigned to treatment with ACZ or placebo, and 25 controls with similar gender, age and body mass index (BMI)...

We report a rare case of intracranial hypertension following high dose cytosine arabinoside (HiDAC) in a 20-year-old man, with precursor B-cell acute lymphoblastic leukemia (ALL). A five drug induction protocol for ALL was initiated; post induction consolidation was with HiDAC (3 g/m(2) IV every 12 h on days 1, 3 and 5). Post consolidation, cytogenetic remission was attained and he received an intensification and maintenance regimen for ALL, for a period of approximately 24 months. Four months following the completion of his treatment, the patient relapsed within the central nervous system (CNS)...

OBJECTIVE Idiopathic intracranial hypertension (IIH) may cause blindness due to elevated intracranial pressure (ICP). Venous sinus stenosis has been identified in select patients, leading to stenting as a potential treatment, but its effects on global ICP have not been completely defined. The purpose of this pilot study was to assess the effects of venous sinus stenting on ICP in a small group of patients with IIH. METHODS Ten patients for whom medical therapy had failed were prospectively followed. Ophthalmological examinations were assessed, and patients with venous sinus stenosis on MR angiography proceeded to catheter angiography, venography with assessment of pressure gradient, and ICP monitoring...

Idiopathic intracranial hypertension(IIH) is a kind of diffuse brain swelling disease. Several causes could lead to IIH. Intracranial venous circulatory disturbance is more common. The clinical manifestations include intracranial pressure increased, headache and papilledema. Since IIH usually has serious impact on vision even blindness, the diagnosis and corresponding treatment are especially important. This review is to discuss the new insights on the therapeutic options of IIH, which cover medical treatment, weight-losing therapy, surgical treatment, interventional therapy and supportive treatment...

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...

BACKGROUND: Some patients undergoing dural sinus stenting for idiopathic intracranial hypertension (IIH) develop clinical and hemodynamic failure (recurrence of the pressure gradient) owing to stent-adjacent stenosis. OBJECTIVE: To characterize factors associated with hemodynamic failure, and to describe outcomes of patients after repeat stenting. MATERIALS AND METHODS: We reviewed the initial and follow-up clinical, venographic, and hemodynamic data in 39 patients with IIH treated over 17 years with stenting...

In this work, the biomechanical responses of the optic nerve head (ONH) to acute elevations in intracranial pressure (ICP) were systematically investigated through numerical modeling. An orthogonal experimental design was developed to quantify the significance levels of ten input factors that govern the anatomy and material properties of the ONH model on the peak maximum principal strain (MPS) in the laminar cribrosa (LC) and post-laminar neural tissue (PLNT). Results show that the sensitivity of ONH responses to various input factors was region-specific...

BACKGROUND: Primary diffuse leptomeningeal primitive neuroectodermal tumor (PDL PNET) is extremely rare, with only 19 cases reported in the literature to date. We present a case of a child with rapidly progressive PDL PNET and a literature review. A 10-year-old boy presented with mood lability, hallucinations, generalized pain, enuresis, and headaches. Initial investigation failed to produce a diagnosis. The symptoms progressed to seizure, back pain, and papilledema. Imaging showed acute hydrocephalus and mild diffuse leptomeningeal enhancement without an identifiable primary lesion...

Marc J Dinkin, Athos Patsalides
Idiopathic intracranial hypertension causes headache, papilledema and visual field loss, typically in obese women of childbearing age. Its anatomical underpinnings remain unclear, but a stenosis at the junction of the transverse and sigmoid sinuses has been recognized in the majority of patients through venography. The stenosis may result from intrinsic dural sinus anatomy or extrinsic compression by increased intracranial pressure, but in either case, its stenting has been shown to lead to an improvement in symptoms of intracranial hypertension and papilledema in multiple retrospective, non-controlled studies...

Idiopathic intracranial hypertension (IIH) is a disorder of elevated intracranial pressure of unknown cause occurring predominantly in young women of childbearing age. The typical patient symptom profile is the presence of daily headache, pulse synchronous tinnitus, transient visual obscurations, and papilledema with its associated visual loss. Although surgical procedures are performed for those who fail medical therapy, their relative efficacy remains unclear. The main morbidity of IIH is from visual loss...

BACKGROUND: Cystinosis is a rare systemic lysosomal disease affecting mainly the kidney and eye. Ocular involvement in cystinosis is universal being the presence of cystine crystals in the cornea a diagnostic criterion and one of the earliest manifestations of the disease. Neuro-ophthalmologic manifestations are considered a rare and late complication in these patients. The aim of this article is to report the unexpectedly high incidence of intracranial hypertension in children with cystinosis at our centre...

The Arnold-Chiari Type 1 malformation (CM1) is a rare congenital abnormality characterized by ectopia or caudal herniation of the cerebellar tonsils through the foramen magnum into the cervical spine, resulting in crowding at the craniocervical junction. It seldom presents in childhood with symptoms and a normal neurological examination. More typically, CM1 presents in young adult women with neurological symptoms including a headache, cervical pain, cranial nerve palsies, neurosensory deficit, and ataxia. Ocular manifestations associated with Chiari I include third and sixth cranial nerve paresis and convergence/divergence abnormalities...

Among the symptoms of hypocalcemia, tetany, papilledema, and seizures may occur in patients who develop hypocalcemia acutely. We describe a rare case of hypocalcemia presenting as schizophreniform disorder. Among other presentations of hypocalcemia, one should also look for the relation between psychotic symptoms and calcium levels in a patient presenting with psychotic symptoms.
