BACKGROUND AND PURPOSE Wernicke encephalopathy (WE) is a severe neurologic disorder resulting from dietary vitamin B(1) deficiency. This study was undertaken to analyze and compare MR imaging findings and neurologic manifestations at clinical presentations of patients with WE with and without a history of alcohol abuse. MATERIALS AND METHODS WE patients(More)
BACKGROUND Management of glioblastoma multiforme (GBM) has been difficult using standard therapy (radiation with temozolomide chemotherapy). The ketogenic diet is used commonly to treat refractory epilepsy in children and, when administered in restricted amounts, can also target energy metabolism in brain tumors. We report the case of a 65-year-old woman(More)
Little attention has been given to the fetal-type posterior circle of Willis (FTP) in the literature; also symptomatic basilar artery (BA) hypoplasia has been rarely reported. We aimed to illustrate that the association of a hypoplastic vertebrobasilar system (VBS) with the FTP may lead to posterior circulation ischemia. Magnetic resonance imaging and(More)
OBJECTIVE To investigate the clinical, genetic, and neuroradiologic data of biotin-responsive basal ganglia disease (BBGD) and clarify the disease spectrum. METHODS We first investigated all patients attending our Division of Pediatric Neurology with a genetically proven diagnosis of BBGD between 2009 and 2011. All patients underwent a detailed medical(More)
BACKGROUND AND PURPOSE Wernicke encephalopathy is a severe neurologic disorder that results from a dietary vitamin B1 deficiency. It is characterized by changes in consciousness, ocular abnormalities, and ataxia. This study was undertaken to analyze and compare findings on MR imaging and neurologic symptoms at clinical presentations of patients with(More)
Wernicke encephalopathy (WE) is an acute neurological disease resulting from dietary thiamine (vitamin B1) deficiency. WE is characterized by changes in consciousness, ocular dysfunction, and ataxia. Neuroradiologic findings usually show symmetric signal intensity alterations in the mammillary bodies, medial thalami, tectal plate, and periaqueductal area.(More)
Glioblastoma multiforme is the most common malignant primary brain tumor in adults and generally considered to be universally fatal. Glioblastoma multiforme accounts for 12% to 15% of all intracranial neoplasms and affects 2 to 3 adults per every 100,000 in the United States annually. In children glioblastoma multiforme accounts for only approximately 7% to(More)
BACKGROUND AND PURPOSE Iterative reconstruction techniques facilitate CT dose reduction; though to our knowledge, no group has explored using iterative reconstruction with pediatric head CT. Our purpose was to perform a feasibility study to assess the use of ASIR in a small group of pediatric patients undergoing head CT. MATERIALS AND METHODS An(More)
We report a patient with clinical and neuroimaging findings of spontaneous intracranial hypotension (SIH) who developed cerebral venous thrombosis (CVT). An association between SIH and CVT has rarely been observed. Anticoagulation therapy was administered. The clinical course was subsequently complicated by a large subdural hematoma that required(More)
