We describe a case of a man aged 41 years who presented with a history of generalised headaches for 1 week and an acute episode of tonic-clonic seizures. He had no history of medical illness, was non-smoker, with an extensive family history of haematological disorders. Initial CT brain with contrast did not show any abnormalities in brain parenchyma. X-ray and CT right shoulder showed shoulder dislocation secondary to trauma associated with seizure prior to hospital admission. Subsequently, MRA and MRV brain was arranged, which revealed extensive expansible occlusive filling defect dominating the middle of superior sagittal sinus with left frontal cortical and subcortical acute oedema...

Head CT scan is more often used to evaluate patients with suspected traumatic brain injury (TBI). However, the use of head CT scans in evaluating TBI is costly with low value endeavor. In this paper, we propose a new algorithm and a set of features to help clinicians determine which patients evaluated for TBI need a head CT scan using cost sensitive random forest (CSRF) classifier. We show that random forest (RF) and CSRF are useful methods for identifying patients likely to have a positive head CT scan. The proposed algorithm has superior diagnostic accuracy in comparison to the Canadian head CT algorithm, which is currently the most accurate and widely used algorithm for determining which TBI patients need a head CT scan...

INTRODUCTION: Patients with nontraumatic acute intracranial pathology benefit from neurointensivist care. Similarly, trauma patients with and without traumatic brain injury (TBI) fare better when treated by a dedicated trauma team. No study has yet evaluated the role of specialized neurocritical (NICU) and trauma intensive care units (TICU) in the management of TBI patients, and it remains unclear which TBI patients are best served in NICU, TICU, or general (Med/Surg) ICU. METHODS: This study is a secondary analysis of The American Association for the Surgery of Trauma Multi-Institutional Trials Committee (AAST-MITC) decompressive craniectomy study...

Steady-state free precession (SSFP) magnetic resonance imaging (MRI) can demonstrate details down to the cranial nerve (CN) level. High-resolution three-dimensional (3D) visualization can now quickly be performed at the workstation. However, we are still limited by visualization on flat screens. The emerging technologies in rapid prototyping or 3D printing overcome this limitation. It comprises a variety of automated manufacturing techniques, which use virtual 3D data sets to fabricate solid forms in a layer-by-layer technique...

INTRODUCTION: Traumatic Brain Injury (TBI) is of public health interest and produces significant mortality and disability in Colombia. Calculators and prognostic models have been developed in order to establish neurologic outcome. We tested prognostic models (the Marshall CT score, IMPACT, and CRASH) for 14-day mortality, 6-month mortality, and 6-month outcome in TBI patients in a university Hospital in Colombia. METHODS: A 127 patients' cohort with TBI was treated in a regional trauma center in Colombia over 2 years and Bivariate and Multivariate analyses were used...

PURPOSE: We conducted a survey of providers to assess for practice patterns in diagnosing and treating new-onset refractory status epilepticus (NORSE). NORSE is the occurrence of prolonged seizures that are not responsive to initial therapies in otherwise healthy individuals without obvious cause on initial presentation. This entity is thought to have multiple etiologies, including autoimmune. METHOD: A 29-question electronic survey was sent to providers included in the Neurocritical Care Society emailing list...

We report the case of a 14-year-old girl with clinically diagnosed Kleine-Levin syndrome. Electroencephalogram and brain MRI were unremarkable. An FDG PET/CT scan was acquired during a symptomatic episode, while she was asleep, and another PET scan was obtained when she was asymptomatic, awake, and quiet. Comparison of both examinations demonstrated a bilateral activation of thalami, caudate nuclei, and lenticular nuclei. These findings may be linked to the implication of thalamostriatal structures in the regulation of sleep and wakefulness...

A 39-year-old man presented with new onset of sinus congestion, shortness of breath, and diaphoresis. His laboratory tests were notable for hypercalcemia and lactic acidosis. A CT scan of the head demonstrated mild paranasal disease. CT scan of the chest, abdomen, and pelvis demonstrated omental caking with lymphadenopathy and a thickened loop of bowel in the left upper quadrant suggestive of lymphoma. All abdominal lesions seen in the CT were intensely F-FDG avid with diffuse uptake in the bone marrow. There was markedly decreased F-FDG uptake in both the brain and liver...

BACKGROUND: Aneurysmal subarachnoid hemorrhage (SAH) accounts for 5% of strokes and carries a poor prognosis. It affects around 6 cases per 100,000 patient years occurring at a relatively young age. METHODS: Common risk factors are the same as for stroke, and only in a minority of the cases, genetic factors can be found. The overall mortality ranges from 32% to 67%, with 10-20% of patients with long-term dependence due to brain damage. An explosive headache is the most common reported symptom, although a wide spectrum of clinical disturbances can be the presenting symptoms...

Case report describing the finding of central pontine myelinolysis (CPM) using combined fluorine-18 ( (18)F)-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). The patient was a known alcoholic who, during admission was under treatment for hyponatremia, showed a significant decline in both motor and cognitive function. Combined (18)F-FDG PET/CT showed localized FDG uptake in the pons, consistent with the finding of CPM observed on magnetic resonance imaging (MRI). CPM is a demyelinating lesion of the pons, resulting in several neurological symptoms...

BACKGROUND: In the setting of trauma, the etiology of intracranial hemorrhage (ICH) is frequently attributed to the physical, traumatic event. Caution should still be directed towards non-traumatic (or spontaneous) etiologies responsible for the trauma, such as hypertension, cerebral amyloid angiopathy, aneurysms, vascular malformation, and hemorrhagic infarcts. The role for immediate CT angiography (CTA) remains controversial to evaluate for non-traumatic etiologies. METHODS: A systematic review of the available literature in Medline PubMed database...

In this paper, we introduce a novel model of the brain vascular system, which is developed based on laws of fluid dynamics and vascular morphology. This model is used to address dispersion and delay of the arterial input function (AIF) at different levels of the vascular structure and to estimate the local AIF in DCE images. We developed a method based on the simplex algorithm and Akaike information criterion to estimate the likelihood of the contrast agent concentration signal sampled in DCE images belonging to different layers of the vascular tree or being a combination of different signal levels from different nodes of this structure...

Ontogenetic changes in skull shape and size are ubiquitous in altricial vertebrates, but typically unidirectional and minimal in full-grown animals. Red-toothed shrews exhibit a rare exception, where the shape, mass and size of the skull, brain, and several major organs, show significant bidirectional seasonal changes. We now show a similar but male-biased shrinking (16%) and regrowth (8%) in the standardized braincase depth of least weasels (Mustela nivalis). Juvenile weasels also exhibit a growth overshoot, followed by a shrinkage period lasting until the end of their first winter...

Attempts at reconstruction of posttraumatic craniofacial defects (PTCDs) can be a challenge in low-resource practice areas of the world where the needed biomaterials are logistically beyond reach. A simple low-profile technique of autologous osteosynthesis for PTCD using the titanium clamps is presented in this report. In addition, a 6-year prospective database on a consecutive cohort of patients who underwent this procedure was analyzed for clinical, functional, and aesthetic outcomes, both in-hospital and at midterm follow-up...
