BACKGROUND: Complex hydrocephalus affecting lateral and fourth ventricles separately is occasionally managed with CSF diversion via supra- and infra-tentorial ventricular catheters. The optimal configuration to reduce complications is currently unknown in adults. We describe a consistently similar clinical presentation of patients with complex hydrocephalus and a fourth ventricle separately drained by infra-tentorial shunt insertion. METHODS: A retrospective single centre case series...

Objective: Acute subdural hematoma (ASDH) is generally considered a condition that should be managed surgically. However, some patients initially receive conservative treatment, a subset of whom require surgical intervention later. This study aimed to evaluate the predictors of delayed surgical intervention in ASDH patients who are initially managed conservatively. Methods: From January 2007 to December 2015, 842 patients diagnosed with ASDH were treated at our institution...

A rare acquired demyelinating lesion of the pons central pontine myelinolysis (CPM) typically occurs after rapid correction of hyponatremia. There is disruption of blood-brain barrier due to osmotic stress allowing access for inflammatory mediators in extravascular brain tissue, which most likely attracts glial cells of the brain, attracts macrophages, and activates astrocytes. We present a case of female with a known history of inflammatory bowel disease who presented with altered sensorium and hyponatremia...

OBJECTIVE: Decompressive craniectomy (DC) is used to treat intractable intracranial hypertension following severe traumatic brain injury (TBI). Cranioplasty (CP) is typically performed weeks or months later. However, the optimal timing for CP is unknown. We aimed to determine the earliest possible time point for CP. METHODS: We retrospectively reviewed brain computed tomography (CT) images from 159 patients who underwent CP following DC for TBI at 3 hospitals. We determined the earliest possible day for CP by reviewing the resolution of intracranial pressure in serial brain CT images between DC and CP...

BACKGROUND: Cranioplasty is considered a low-risk operation in the field of neurosurgery following decompression craniectomy (DC). Well-known complications after cranioplasty, such as infection, seizure, and titanium plate exposure, may not threaten the lives of patients. Unfortunately, there are many fatal complications that are under reported. In this study, we report a case and perform a literature review to introduce malignant cerebral swelling, which is regarded as a devastating complication...

There is growing concern about the frequency of computed tomographic (CT) scans performed for evaluation of adults with suspected mild traumatic brain injury. The Canadian CT Head Rule and the New Orleans Criteria are the most studied head CT decision tools that aid providers in determining which patients do not require a CT scan. This article examines recent research to determine which of these tools has proven to be the most effective at safely reducing the use of head CT scans. The reviewed studies concluded that both the Canadian CT Head Rule and the New Orleans Criteria had similar sensitivities, but the Canadian CT Head Rule showed superior specificity in predicting the presence of a clinically significant brain injury...

Imaging plays a central role for intravenous and intra-arterial arterial ischemic stroke treatment patient selection. Computed tomography (CT) / CT angiography or magnetic resonance (MR) / MR angiography imaging are used to exclude stroke mimics and haemorrhage, to determine the cause and mechanism of stroke, to define the extension of brain infarct and to identify the arterial occlusion. Imaging may identify the patients that will be benefit more from revascularization therapies independently of the conventional therapeutic time window allowing individualized treatment decisions and improving individual patient outcome...

BRAF protein is a serine/threonine kinase with 766 amino acids. Approximately 15% of human cancers harbor BRAF mutations as well as other BRAF anomalies (amplifications, fusions). Somatic mutations mainly occur in the catalytic kinase domain (CR3), and the predominant mutation is p.V600E which is the substitution of glutamic acid (E) for valine (V) as result of a mutation at codon 600 of the kinase domain. To our knowledge, the vast majority of the cancers have non-germline BRAF mutations. Here we describe a case of a 60-year-old female with a history of hairy cell leukemia (HCL) who presented with aphasia and forgetfulness...

Arterial calcification (AC), a frequent finding on imaging studies, has been reported as a risk factor for ischemic stroke. However few studies have explored the association of AC with etiological subtypes and prognostic implications. The purpose of this study was to investigate the association of AC with demograhics, risk factors and etiological subtypes and to determine whether it predicts stroke recurrence and functional outcome in patients with acute brainstem ischemic stroke. We analyzed our database consisting of patients who were diagnosed as acute brainstem ischemic stroke admitted within 24hours of onset...

With increasing use of low-dose screening CT scans, the diagnosis of early-stage small-cell lung cancer (SCLC) without evidence of mediastinal nodal or distant metastasis is likely to become more common, but the role of adjuvant therapies such as prophylactic cranial irradiation (PCI) are not well understood in this population. We performed a review of the literature pertaining to the impact of PCI in patients who underwent surgical resection of early-stage SCLC. Four studies were identified that were pertinent including three single-institution retrospective analyses and a National Cancer Database analysis...
