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...

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological syndrome characterized by reversible vasogenic edema typically at a posterior location of the cerebrum. PRES with prominent brainstem or basal ganglia involvement is defined as central-variant, which is rare. We herein report an atypical case of a 35-year-old man with a 2-year history of untreated hypertension who complained of recurrent dizziness. The patient presented with brainstem and diffuse white matter involvement associated with intracranial hemorrhage and recovered fully after therapy...

Jennifer is a 16-year-old Latina girl who is new to your practice. During her first well visit, she mentions that she has had daily headaches for 2 years. They began after sustaining a concussion in a car accident. Typically, her headaches are bilateral and "squeezing"; they occur in the afternoons and last for a few hours. Her concussion also resulted in depressed mood, which has improved over time.When you ask if her headaches have changed recently, she says that they have been worse for the last few days...

BACKGROUND: Endoscopic endonasal repair of cerebrospinal fluid (CSF) rhinorrhea secondary to idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri or benign intracranial hypertension, has varying success rates, from 25-87%, with minimal morbidity. However, often these series have a relatively short-term follow-up. Given the pathophysiology of IIH, long-term follow-up is necessary to identify true CSF leak recurrence rates. Our investigation aimed to evaluate long-term outcomes in endoscopically repaired CSF leaks...

Benign intracranial hypertension (BIH) is a rare but potentially serious condition causing visual loss. Occasionally, medication use has been associated with the occurrence of BIH. We report the case of a 40-year-old obese lady being treated with risperidone for schizophrenia who presented with features of BIH. We report this case, occurring for the 1(st) time in India, to emphasize that a commonly used atypical antipsychotic drug can rarely cause BIH leading to visual loss.

BACKGROUND: The neurological manifestations of Systemic Lupus Erythematosus (SLE) are varied and incompletely described. A few case series report a benign idiopathic intracranial hypertension (IIH) related to SLE, which is responsive to immunotherapy. There are limited reports of patients with malignant cerebral edema, and diffuse white matter changes in the absence of central nervous system (CNS) vasculitis. METHODS: Case series from our tertiary care center and review of the relevant literature...

BACKGROUND: Devices enabling long-term intracranial pressure monitoring have been demanded for some time. The first solutions using telemetry were proposed in 1967. Since then, many other wireless systems have followed but some technical restrictions have led to unacceptable measurement uncertainties. In 2009, a completely revised telemetric pressure device called Neurovent P-tel was introduced to the market. This report reviews technical aspects, handling, possibilities of data analysis, and the efficiency of the probe in clinical routine...

A remote cerebellar hemorrhage (RCH) is a spontaneous bleeding in the posterior fossa, which may rarely occurs as a complication of supratentorial procedures, and it shows a typical bleeding pattern defined "the zebra sign." However, its pathophysiology still remains unknown. We performed a comprehensive review collecting all cases of RCH after supratentorial craniotomies reported in literature in order to identify the most frequently associated procedures and the possible risk factors. We assessed percentages of incidence and 95 % confidence intervals of all demographic, neuroradiological, and clinical features of the patients...

Benign intracranial hypertension is characterized with increase in CSF opening pressure with no specific etiology. It is predominantly found in women of child bearing age and particularly in individuals with obesity. Visual disturbances or loss and associated headaches are common and can lead to blindness if left untreated. Diagnosis can be achieved once other causes of visual loss, headaches and high opening pressures are excluded. Management consists of serial optic disc assessments although no specific treatment is available despite recent trials using carbonic anhydrase inhibitors...

Neurenteric cysts (NEC) are uncommon, benign, congenital lesions. Ventral foramen magnum (FM) location is very rare. The difficulties in diagnosis and management aspects are detailed with a review of the pertinent literature. We report four new cases of ventral FM NEC, all managed surgically and present a literature review of ventral FM NEC. A retrospective analysis of histopathologically confirmed cases of ventral FM NEC, operated from 2010-2013 at our institute, was performed. For review, only those cases of NEC extending from the lower clivus to the C2 level constituting the foramen magnum were included...

Meningiomas are common and mostly benign intracranial tumors, but may show a histological progression to malignancy. The mechanisms of malignant transformation remain unclear. Malignant meningiomas usually bear a high recurrence rate and unfavorable prognosis, and multiple surgical resections are required for the treatment. We report on a case of 51-year-old woman with a histologically benign intracranial meningioma. The patient had undergone multiple tumor resections and radiotherapy treatments. After multiple resections, the tumor demonstrated malignant transformation...

BACKGROUND: The primary role of brain imaging in idiopathic intracranial hypertension (IIH) is to exclude other pathologies causing intracranial hypertension. However, subtle radiologic findings suggestive of IIH have emerged with modern neuroimaging. This review provides a detailed description of the imaging findings reported in IIH and discusses their possible roles in the pathophysiology and the diagnosis of IIH. EVIDENCE ACQUISITION: References were identified by searches of PubMed from 1955 to January 2015, with the terms "idiopathic intracranial hypertension," "pseudotumor cerebri," "intracranial hypertension," "benign intracranial hypertension," "magnetic resonance imaging," "magnetic resonance venography," "computed tomography (CT)," "CT venography," "imaging," and "cerebrospinal fluid (CSF) leak...

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...

INTRODUCTION: Intradiploic epidermoid intracranial cysts (IEIC) derive from ectodermal cells and are covered with stratified squamous epithelium. They are extremely rare, and most common locations are in the occipital, frontal and parietal bones. They have a very slow growth and can be asymptomatic until becoming evident by the deformation produced. The treatment is based on the removal of the lesion, and subsequent histopathological confirmation. PRESENTATION OF CASE: Two cases are reported, with intracranial hypertension syndrome, which is very uncommon because of the slow growth of this type of pathology; however, decompensations occurring in the space-occupying lesions at intracranial level explain this type of clinical presentation...

BACKGROUND: Congenital insulin resistance syndromes are caused by biallelic mutations within the insulin receptor gene (INSR). Recombinant human insulin-like growth factor (rhIGF1) has been used with mixed success; however, rigorous assessment of its efficacy is lacking. Here, we describe a child with a homozygous mutation in INSR successfully treated with rhIGF1 for more than 5 years. CASE REPORT: The patient presented with osmotic diabetes symptoms and was noted to have dysplastic dentition, hypertrichosis, coarse and dysmorphic facial features...

Bronchial asthma (BA) and Allergic rhinitis (AR) are common clinical problems encountered in day to day practice, where inhalational corticosteroids (ICS) or intranasal steroids (INS) are the mainstay of treatment. Iatrogenic Cushing syndrome (CS) is a well known complication of systemic steroid administration. ICS /INS were earlier thought to be safe, but now more and more number of case reports of Iatrogenic Cushing syndrome have been reported, especially in those who are taking cytochrome P450 (CYP 450) inhibitors...
