<h3>BACKGROUND AND PURPOSE:</h3> In cerebral gliomas, rCBV correlates with tumor grade and histologic findings of vascular proliferation. Moreover, ADC assesses water diffusivity is inversely correlated grade. the present work, we have studied whether combined values improve diagnostic accuracy MR imaging in preoperative grading gliomas. <h3>MATERIALS METHODS:</h3> One hundred sixty-two patients histopathologically confirmed diffuse gliomas underwent DWI DSC. Mean were compared among groups...
<h3>BACKGROUND AND PURPOSE:</h3> Diffuse gliomas are classified as grades II–IV on the basis of histologic features, with prognosis determined mainly by clinical factors and grade supported molecular markers. Our aim was to evaluate, in patients diffuse gliomas, relationship relative CBV ADC values overall survival. In addition, we also propose a prognostic model based preoperative MR imaging findings that predicts survival independent histopathology. <h3>MATERIALS METHODS:</h3> We conducted...
Traumatic brain injuries represent an important cause of death for young people. The main objectives this work are to correlate stem detected at MR imaging with outcome 6 months in patients severe TBI, and determine which findings could be related a worse prognosis.One hundred eight TBI were studied by the first 30 days after trauma. Brain injury was categorized as anterior or posterior, hemorrhagic nonhemorrhagic, unilateral bilateral. Outcome measures GOSE Barthel Index postinjury....
<h3>PURPOSE:</h3> Our aim was to study the association between abnormal findings on chest and brain imaging in patients with coronavirus disease 2019 (COVID-19) neurologic symptoms. <h3>MATERIALS AND METHODS:</h3> In this retrospective, international multicenter study, we reviewed electronic medical records of hospitalized COVID-19 from March 3, 2020, June 25, 2020. inclusion criteria were diagnosed Severe Acute Respiratory Syndrome 2 (SARS-CoV-2) infection acute manifestations available CT...
Cranioplasties are performed to protect the brain and correct cosmetic defects, but there is growing evidence that this procedure may result in neurological improvement. We prospectively studied cranioplasties at our hospital over a 5-year period. The National Institute of Health Stroke Scale Barthel index were recorded prior within 72 h after cranioplasty. A perfusion computed tomography (PCT) transcranial Doppler sonography (TCDS) surgery. For PCT, regions irrigated by anterior cerebral...
Purpose. Basal cell carcinoma (BCC) is the most frequent malignant periocular tumor. It associated with exposure to ultraviolet radiation, and its incidence gradually increasing. may occasionally display more aggressive behavior result in orbital or intracranial invasion. Mortality from BBC invasion very low, but morbidity can be significant, disfigurement blindness. Traditionally, these cases have been treated exenteration radiotherapy (RT), recent years, hedgehog pathway inhibitors (HPIs)...
ABSTRACT A 41‐year‐old male presented with an acute onset of headache, confusion, seizures, and unilateral focal neurological deficit 25 years after receiving whole‐brain radiation therapy to treat a cerebellar medulloblastoma. Brain magnetic resonance imaging (MRI) demonstrated thick parieto‐occipital cortical contrast enhancement. diagnosis “Stroke‐like Migraine Attacks Radiation Therapy” (SMART) syndrome was made. Here, we describe the brain MR spectroscopy findings SMART, showing...
Orbital tumor surgery can be challenging when the is located in a very narrow surgical field and close to important structures, such as nerves or extraocular muscles that damaged during surgery. Advances technology special techniques help avoid damage. We describe our experience using SONOPET® ultrasonic aspirator remove 12 different orbital tumors were difficult treat due their poorly defined borders, adhesions, location.This retrospective case series describes operations occurred between...
A 40-year-old woman with well-controlled HIV infection had a vertebrobasilar stroke secondary to endocarditis by Coxiella burnetii (figure 1), left hemiparesis remaining.
Giant cell reparative granuloma (GCRG) is a rare fibroosseous lesion uncommonly seen in the orbital area. Although benign, it known to be recurrent and locally destructive. We report two cases of GCRG orbit. In both cases, computed tomography revealed heterogeneously growing well-defined mass, arising from roof orbit, affecting cortex, invading first case, mass extended into anterior cranial fossa. Magnetic resonance imaging with gadolinium showed, cystic character fluid levels. The surgical...
Purpose The superior orbital fissure contains cranial nerves III, IV, VI, and V1 with their three branches: frontal, lacrimal, nasociliary. Superior syndrome (SOFS) is rare can occur as a result of compression these due to trauma, bleeding, or inflammation in the retrobulbar space, but no cases SOFS after deep lateral wall decompression (DLOWD) have been reported. aim this paper describe pathology, its possible causes, management, outcome.
Background Cranial dural arteriovenous fistulas (dAVFs) are complex neurovascular malformations accounting for approximately 10%–15% of all intracranial malformations. The objective is to investigate the utility susceptibility-weighted imaging (SWI) in identifying “hypointense focal brain” as an additional helpful sign venous congestion cranial dAVFs. Materials and Methods A retrospective review patients diagnosed with dAVFs between January 2015 June 2023 was conducted, SWI used identify...
