Chiari malformation Type I (CM-I) with an associated spinal syrinx is a common pediatric diagnosis. A better understanding of the relative age-related prevalence and MR imaging characteristics these conditions may lead to improved treatment decisions.The authors performed retrospective review 14,116 consecutive individuals 18 years age or younger who had undergone brain cervical spine at University Michigan between November 1997 August 2008. In patients CM-I, demographic, clinical,...
Object The natural history of the Chiari malformation Type I (CM-I) is incompletely understood. authors report on outcome a large group patients with CM-I that were initially selected for nonsurgical management. Methods identified 147 in whom was diagnosed MR imaging, who not offered surgery at time diagnosis, and least 1 year clinical imaging follow-up available after initial diagnosis. These included an analysis. Results Patients followed clinically by mean duration 4.6 3.8 years,...
Prior attempts to define normal cerebellar tonsil position have been limited by small numbers of patients precluding analysis distribution age group. The authors' objective in the present study was analyze location every range.Two thousand four hundred were randomly selected from a database 62,533 consecutive undergoing MRI and organized into 8 groups. Magnetic resonance images directly examined for location, morphology, other features. Patients with history or imaging findings posterior...
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by multiple immunologic abnormalities and has the potential to involve central nervous system (CNS). The prevalence of SLE seems be growing, possibly because earlier diagnosis improved survival; however, associated mortality still high. with disease-related risk factors such as activity, young age, organ damage or antiphospholipid syndrome (APS). Neuropsychiatric (NPSLE), which caused SLE-related CNS...

To resolve the diagnostic dilemma of allergic fungal rhinosinusitis (AFRS), an increasingly recognized type chronic (CRS). In spite extensive studies, controversy exists regarding etiologic characteristics, pathogenesis, and diagnosis this entity.Prospective, comparative study.Department Otolaryngology-Head Neck Surgery, Postgraduate Institute Medical Education Research, Chandigarh, India.Seventy consecutive patients with CRS, or without polyps.Patients were evaluated by detailed clinical...
OBJECT Chiari malformation Type I (CM-I) is often found in patients with scoliosis. Most previous reports of CM-I and scoliosis have focused on a spinal syrinx. The relationship between the absence syrinx has never been defined clearly. authors sought to determine if there an independent association when controlling for status. METHODS medical records 14,118 consecutive aged ≤ 18 years who underwent brain or cervical spine MRI at single institution 11-year span were reviewed identify CM-I,...
Differentiating pseudoprogression from true tumor progression has become a significant challenge in follow-up of diffuse infiltrating gliomas, particularly high grade, which leads to potential treatment delay for patients with early glioma recurrence. In this study, we proposed use multiparametric MRI data as sequence input the convolutional neural network recurrent based deep learning structure discriminate between and progression. 43 biopsy-proven patient identified whose disease...
To assess the visual outcome in cases of traumatic optic neuropathy treated with a combined therapy protocol methylprednisolone injections and endoscopic nerve decompression.Prospective, nonrandomized study.Academic tertiary care referral center.The study included 44 patients posttraumatic indirect injury.Visual acuity.Visual improvement was achieved 31 (70%) when treatment initiated within 7 days injury, whereas only 10 (24%) showed started after more than days. The time lapse injury...
Distinguishing schwannomas from paragangliomas in the head and neck determining succinate dehydrogenase (SDH) mutation status are clinically important. We aimed to assess clinical usefulness of DWI dynamic contrast-enhanced MR imaging differentiating these 2 types tumors, as well SDH paragangliomas.This retrospective study June 2016 2020 included 42 patients with 15 27 (10 mutation-positive 17 mutation-negative). ADC values, MRI parameters, tumor characteristics were compared between tumors...
The aim of this randomized prospective study was to compare the efficacy endoscopic versus standard microsurgical excision pituitary adenomas, and evaluate merits demerits each approach. Twenty patients with a adenoma were randomly divided into two groups comprising 10 cases each. Ten operated by endonasal trans-sphenoidal approach rhinologist (EETSS group) other excised neurosurgeon (SMETSS group). In both complete achieved in 50% (unpaired t-test, p = 1.00). EETSS group mean operative time...
Objective To outline the clinical and radiologic aspects of symptomatic craniofacial fibro‐osseous lesions to study appropriate surgical management with follow‐up results. Study Design Setting A retrospective review 11 patients who underwent treatment during 1985 2004 in a tertiary health care center. Results Most (72.7%) cases were fibrous dysplasia under 25 years age (72%). Maxilla was most common bone involved (81%). Lateral rhinotomy main approach for resection. One patient bilateral...
We evaluated the utility of amplitude-integrated EEG (aEEG) and regional oxygen saturation (rSO2) measured using near-infrared spectroscopy (NIRS) for short-term outcome prediction in neonates with hypoxic ischemic encephalopathy (HIE) treated therapeutic hypothermia.Neonates HIE were monitored dual-channel aEEG, bilateral cerebral NIRS, systemic NIRS throughout cooling rewarming. The measure was a composite neurologic examination brain MRI scores at 7 to 10 days. Multiple regression models...
Detection and severity assessment of subdural hematoma is a major step in the evaluation traumatic brain injuries. This retrospective study 110 computed tomography (CT) scans from patients admitted to Michigan Medicine Neurological Intensive Care Unit or Emergency Department. A machine learning pipeline was developed segment assess hematoma. First, probability each point belonging region determined using combination hand-crafted deep features. provided initial state segmentation. Next, 3D...
The detection of cervical lymph nodal metastasis and carotid artery invasion by metastatic nodes is an important issue in the management head neck malignancies. This study compared evaluation palpation, ultrasonography (USG) computed tomography (CT) patients with known Twenty-five consecutive malignancy were prospectively evaluated for presence lymphadenopathy invasion. All underwent clinical examination (palpation), USG CT examination. A modified criteria was employed which yielded...
Purpose. Researchers have sought to better understand Chiari type I malformation (CMI) through morphometric measurements beyond tonsillar position (TP). Soft tissue and bone structures within the brain craniocervical junction been shown be different for CMI patients compared healthy controls. Yet, several morphological characteristics not consistently associated with CMI. is also prevalent conditions (PCs) such as syringomyelia, pseudotumor, Ehlers-Danlos syndrome (EDS), scoliosis,...
Background: Idiopathic descent of cerebellar tonsils into the cervical spine in Chiari malformation Type I (CMI) is typically associated with occipital headache. Accumulating evidence from experimental studies suggests cognitive effects CMI. The aim current study was to examine relationship between cognition and CMI using a battery standardized neuropsychological symptom inventory instruments. Method: Eighteen untreated adults CMI, 18 gender, age, education matched healthy controls completed...
