Epilepsy Behav 2006; 8:91. In: Atlas, MRI identifies the role of imaging in Epilepsy in patients. It has been said that MRI adds sensitivity and specificity in evaluation of seizures. Most common clinical manifestation is seizures. Prospective studies of 100 patients with clinical impression of seizures were examined by 1.5 Tesla magnetic resonance imaging. Results: Definitive cases were 28 (70%) and probable cases were 12 (30%). Role of MRI in evaluation of seizures. MRI signal abnormalities induced by seizures. The MRI and MRS examinations were performed in all the patients in one session. The effect of mobile phones on the risk of developing brain tumors has not been established for glioma and meningioma in adults, but the link with acoustic neurinoma is becoming robust. All the patients underwent EEG study prior to the MRI study, unless it was not indicated. Brain-ionizing irradiation, especially during childhood, constitutes a well-established risk factor for brain tumors. Aims: This study was aimed to study the clinical and radiological profile of neurocysticercosis and outcomes of treatment in neurocysticercosis. IAIM, 2018; 5(12): 102-110. Our purpose is to present a case report of bilateral radiation retinopathy with macular edema in one eye that was revealed 6 years after glioma therapy and treated successfully by using monotherapy of aflibercept. Mean age of 29.62 ± 9.08 years. The primary objective is to decide the patient's insight. At the end of 3 months, 23 (57.5%) patients had radiological resolution (complete resolution + partial resolution + calcification). with seizure disorder is in part associated to the underlying pathologies and by the MRI techniques and experience of the interpreting •MRI is highly Superior sagittal sinus thrombos. Conclusion: Although CT scan is more easily available Conclusion: Although CT scan is more easily available and has shorter scan time, MRI is superior in the diagnosis of most of the pathologies. The study revealed that the role of imaging in the evaluation of partial seizure is to localize the origin of a focal seizure and identify its cause. Free Online Library: Role of MRI in evaluation of seizures. Exposure to environmental toxins has been poorly explored and data give inconsistent clues about N-nitroso compounds or pesticides as risk factors of brain tumors even for prenatal exposure. (MRI) in the evaluation of children with seizures.1 MRI is widely used as a tool for the evaluation of children with seizures.2-4 The International League Against Epilepsy (ILAE), moreover, included MRI in the consensus guidelines cerebral atrophy (1%), developmental cortical malformations (2%), venous thrombosis (4%), low-grade glioma (9%), meningioma MRI is also the investigation of choice in the neurodiagnostic workup of recurrent unprovoked seizures, known as epilepsy, for both adults and children. Male:female ratio was 2.07. One hundred and seventy children of chronic seizures with strong clinical suspicion of an underlying intracranial lesion as its cause were studied by Magnetic Resonance Imaging (MRI). protocols. Surface rendering of 3-dimensional MRI datasets can increase the conspicuity of malformations of cortical development without any additional manipulation of the data [32] . However it has limited role in evaluation of patients with intractable epilepsy. It can occur secondary to treatment of nasopharyngeal tumors, as well as intraocular tumors, such as uveal melanoma and retinoblastoma. © 2008-2021 ResearchGate GmbH. This may be particularly useful for MRI-negative patients with seizures originating in deeper cortical areas, such as orbitofrontal cortex where scalp EEG may not be as accurate . Complex partial seizures and mesial temporal sclerosis: evaluation with fast spin-echo imaging. onset seizures. imaging abnormalities depending upon the etiology. Commonest site of lesion was parietal lobe (45%). Join ResearchGate to find the people and research you need to help your work. A total of 512 patients evaluated at the outpatient clinic for intractable epilepsy at the Ribeirão Preto School of Medicine were included in the survey. The sensitivity of MRI in detecting abnormalities in patients Post-stroke seizure and post-stroke epilepsy are common causes of hospital admissions, either as a presenting feature or as a complication after a stroke. One patient showed features of sub-acute, images. We report a case of a 42 year old Nepali man diagnosed with cerebral venous sinus thrombosis after presenting with a week long history of continuous headache. •The structural abnormality often (but not always) correlates with the site of seizure onset. Fundoscopy and fluorescein angiography revealed severe non-proliferative retinopathy in his right eye and proliferative retinopathy in his left eye with macular edema. excellent inherent soft tissue contrast, multiplanar imaging capability and lack of ionizing radiation, MR imaging has emerged as a From this oedema centre, water content very slowly and gradually decreased along the oedema projection into the deep white matter. Our report highlights the value of prompt diagnosis of cerebral venous sinus thrombosis through neuroimaging and the importance of immediate anticoagulation as part of patient management. Following complete work-up and due to his past medical history, he was diagnosed with radiation retinopathy. It is assumed that the spatial distribution and extension of oedema around a brain tumour is determined by a system of differential resistance to fluid movement in the following order: grey matter--ventricular lining--white matter. Kast, . MRI has superior resolution in delineation of brain anatomy and higher diagnostic yield for epileptogenic lesions. Evan's index, a specific parameter for measurement of cerebral atrophy was calculated on MR images and was used in this study. seizures (3), inherited metabolic disorder, possibly Leigh’s disease (2). Seventy Six Children (0-12 yr) with seizures and CNS malformations based on neuroimaging were included. MRI is the investigation of choice in patients with seizure disorder. The results are well in concordance with the previous data published on this issue. According to the literature, there is minimal experience using aflibercept monotherapy to successfully treat macular edema due to radiation retinopathy. Abnormal MRI was found in 17 (27.0%) patients with partial seizures, 13 (15.8%) patients with generalized seizures, and 1 (10%) patients with CFS. The main aim of the study was to determine the frequency of cerebral atrophy in type-II diabetes mellitus using magnetic resonance imaging of the brain. Neuroimaging included brain CT with non-contrasted and contrasted phases and high resolution MRI. From the 40 patients included in our study, 16 patients had tendon injuries. The EEG and magnetic resonance imaging findings were correlated with postoperative histopathological findings in cases where required. GTCS was the most common clinical diagnosis constituting •The primary role of neuroimaging is to identify structural abnormalities that underlie seizure disorders. Role of MRI in Evaluation of Traumatic Ankle Injuries 2019 Fig. Leslie A Hartman, MD; Sara R Nace, MD; Jane H All cases of young and adult onset epilepsy in tropical countries should be investigated for neurocysticercosis. All the patients were undergone MRI of brain using 1.5 Tesla power magnetic resonance imaging machine ofPicker Company. Vivek Gupta and Richard A Bronen. All rights reserved. Accurate diagnosis of the cause of seizure is crucial for finding an effective treatment. MRI with temporal cuts gives attention to hippocampal volumes in assessment for temporal lobe epilepsy. The patient received 6 intravitreal injections of aflibercept in a period of 9 months in order to treat macular edema and radiation retinopathy. Williams and Wilikins; 2009.p. Due to the superior yield, strong consideration for MRI should be given for all infa … Several treatment modalities have been reported including intravitreal, Computerized tomography (CT) was used to study the pathways of oedema spreading in man. The role of CT perfusion in the evaluation of seizures, the post-ictal state, and status epilepticus Author links open overlay panel James J Gugger Rafael H Llinas Peter W Kaplan Show more Whenever a patient has had multiple seizures, or if there is a strong clinical suspicion that a seizure is secondary to an underlying brain lesion (and the CT scan is normal), magnetic resonance imaging (MRI) is usually warranted. MR imaging plays a pivotal role in the evaluation of patients with seizures. The Journal, Editor and the It is the sole responsibility of the Author concerned. Cranial MRI is the most sensitive imaging study for determining the etiology of neonatal seizures, particularly when electrolyte imbalance has been excluded as the seizures… Several authors highlighted the pr ominent role of DWI in disclo sing TPMA (Kim et al., 2001; Szabo et al., 2005). The commonest presentation was seizures in 38 (95%); 29 (72.5%) patients had a single lesion and 11 (27.5%) had multiple lesions in initial imaging study. These data suggest that neurocysticercosis is an uncommon cause of intractable epilepsy, even in an endemic region such as Brazil, and that it may only represent a coexistent pathology.

MRI has been shown to be highly sensitive and specific in identifying Epilepsy Status epilepticus was seen in 6 cases. Medical intractability was determined on the basis of seizure incidence and severity, and response to appropriate epilepsy management. doi: 10.5812/ans.68741 . 4, Issue 105 , December 31; Page: 16977 -16983, DOI: 10.14 260/jemds/20 15/2564 INTRODUCTIO N Subjects and Methods: Forty patients coming under Definitive or Probable Diagnosis of neurocysticercosis as per the revised diagnostic criteria for neurocysticercosis were included in this study. seizures and temporal lobe seizures. Three patients were seen to have glioma. In our study, the majority were male patients (60%). In the pre-CT period the occurrence of epilepsy as a presenting feature in neurocysticercosis was 43.5% whereas in later years it was 61.4%. is a clinical manifestation of abnormal, excessive neuronal activity arising in the grey matter of the cerebral cortex. Accurate diagnosis of the cause of seizure is crucial for finding an effective treatment. They were performed at 1.5 T super conducting system. In addition, radiotherapy for glioma is a rather rare cause of radiation retinopathy compared to other more common causes, such as nasopharyngeal tumors, meningiomas, and uveal melanomas. BACKGROUND The effect of mobile phones has still not been explored in children. To evaluate the role of Magnetic resonance imaging (MRI) in partial seizures and to correlate the MRI findings with EEG (Electroencephalogram) Materials and methods The study was conducted in a tertiary care hospital attached with a teaching institute over a 2 year period. Best corrected visual acuity in his right eye was 20/25 and in his left eye 20/100. Philadelphia, USA: Lippincott (80%) cases. Results MRS was performed in a total of 30 patients. Journal of Evolution of Medical and Den tal Sciences 20 15; Vol. Applied radiology. In male group the frequency of cerebral atrophy was 22 (47%) and in female group it was found to be 23 (43%). is a chronic condition characterized by recurrent seizures unprovoked by an acute systemic or neurologic insult.1 An epileptic seizure Duration of diabetes was five years and more in all the patients as determined by their glycosylated haemoglobin which was >6 in all the patients. The role of FDG-PET, ictal SPECT, and MEG in the epilepsy surgery evaluation. Patients with simple partial seizures The common abnormalities were cerebral infarction with gliosis (16%), infections – NCC (7%) and tuberculoma (10%), Eight generalized seizures, 21 patients (22.1%) presented with focal seizures while 11 patients (11.6%) had an unknown onset. Seizure semiology varied in all categories. Based on the assumption that local changes in CT numbers in oedematous white matter closely correspond to changes in tissue water content, CT numbers of consecutive tissue blocks of 3.0-3.6 mm were examined in the main directions of oedema spreading: towards the deep white matter, towards the cortex and, Adult primary tumors of the central nervous system are rare, but the incidence is increased in some European countries. When we study the overall population the frequency was found to be 45 (45%). An interesting finding was disappearing lesion in 6 children. Epilepsy Imaging: Approaches and protocols. Eighty one cases (54%) who primarily presented as epilepsy without any neurological deficit have been analysed in detail. The basis of diagnosis was clinical presentation and concomitant evidence of extraneural cysticercosis in the pre-computed tomography (CT) scan era, and typical CT findings in later years. and spine, 4 th edition. editorial board are not entitled or liable to either justify or responsible for inaccurate and misleading data if any. Most common stage of presentation was colloidal (55%). Doescher et al .,[ 12 ] who conducted a study on a cohort of normal children with newly diagnosed seizures, found abnormal MRI in 32.6% of patients. Applied radiology. Patients were treated with albendazole, corticosteroids and antiepileptic drugs. Observed anomalies included dysgenetic corpus callosum (DCC), lissencephaly, focal cortical dysplasia (FCD), pachygyria, polymicrogyria, heterotopia, schizencephaly, holoprosencephaly, hemimegalencephaly, and phakomatoses like tuberous sclerosis, Sturge Weber syndrome and linear cutaneous nevus syndrome. ResearchGate has not been able to resolve any citations for this publication. 60.5 percent cases presented in infancy. Cinical history, physical examination and neuroimaging [computed tomography (CT) or magnetic resonance imaging (MRI)] studies were done at the beginning.

One hundred diabetic patients (Random blood sugar >126 mg/dl) were recruited in this study after the informed consent from every patient. This article examines aetiology, clinical presentation, and presents a management outline of these conditions with particular focus on adults. The new larvicidal drugs offer a potential cure and cysticercosis should be entertained as a cause of epilepsy especially in endemic areas. A total of 100 patients satisfying the inclusion criteria were included in the study. The study was conducted in a tertiary care hospital attached with a teaching institute over a 2 year period. Maximum number of patients were between 6-12 years, males outnumbering females. 84 patients (88.4%) had positive findings on MRI while 11 patients (11.6%) had normal MRI with no the age Radiation retinopathy is a chronic, progressive retinal microangiopathy which can occur with variable latency after retina exposure to ionizing radiation used for cancer treatment. In these populations, MRI has been shown to have a diagnostic yield ranging from 20% to 64 A 59-year-old male patient presented with gradually deteriorating visual acuity in his left eye for the past 12 months.

Structural abnormalities were seen in 158 of the 170 patients. Role of MRI in evaluation of Alzheimer’s disease: A progressive disease that destroys memory and other Scott W (eds) Magnetic Resonance Imaging of the brain CONCLUSION This finding could suggest either that there is a cause-effect relationship between MTS and neurocysticercosis, or that MTS and neurocysticercosis co-vary with a missing variable, such as socio-economic status. Here we review studies of environmental factors potentially involved in the carcinogenesis of brain tumors: the potential association between. Access scientific knowledge from anywhere. Patients were divided into neurocysticercosis and non-neurocysticercosis groups according to previous diagnostic criteria. 98.57 %. The characteristic EEG features provided a clue to the diagnosis of anomalies like lissencephaly, agenesis of corpus callosum and alobar holoprosencephaly. (2): Types 23 patients (32.8%) had joint effuof ligament's injuries diagnosed by MRI. 307-39. Seizure is a paroxysmal alteration in neurologic function resulting from abnormal excessive neuronal electrical activity. Settings and Design: A prospective observational study conducted in a tertiary care hospital. Cerebral atrophy, a complication of long standing diabetes is quite frequent in our population and is well diagnosed by MRI. The aim of this review article is to provide the clinicians with background information and recommendations.
