1/174. seizures induced by frustration and despair due to unresolved moral and political issues: a rare case of reflex epilepsy.We present a case of reflex-induced simple partial seizures, triggered by feelings of frustration, anger and despair. Such emotions were provoked by pondering over complex national and international, political and moral issues. The present case may suggest that activation of right temporal networks may mediate negative and adverse emotions induced by preoccupation with agitating, controversial issues.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
2/174. Transient MRI enhancement in a patient with seizures and previously resected glioma: use of MRS.A 35-year-old man presented with partial seizures 10 years after resection of a left-sided glioblastoma multiforme. At the old operative site MRI demonstrated extensive cortical and white matter gadolinium enhancement, and PET showed hypermetabolism. biopsy of the area was postponed when MRS showed a normal biochemical spectrum. MRI and PET abnormalities resolved after control of the seizures. MRS is noninvasive and can provide essential information in the management of patients with seizures and previously treated cerebral neoplasms.- - - - - - - - - - ranking = 0.1805374178741keywords = neoplasm (Clic here for more details about this article) |
3/174. pH-dependent cocaine-induced cardiotoxicity.Severe cocaine toxicity causes acidemia and cardiac dysfunction. These manifestations are described in 4 patients who presented with seizures, psychomotor agitation, and cardiopulmonary arrest. Their initial laboratory values demonstrated acidemia and electrocardiographic findings that included a prolonged QRS complex and QTc duration and a rightward T40 ms axis deviation. Treatment of the patients with hyperventilation, sedation, active cooling, and sodium bicarbonate infusion led to the normalization of their blood pHs and reversal of their cardiac conduction disorders. Acidemia can contribute to cocaine cardiac disorders by promoting conduction delays, dysrhythmias, and depressed myocardial contractility. Good supportive care corrects the blood pH and cardiac conduction disorders and remains the major focus in the management of patients with cocaine toxicity.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
4/174. Ictal video-EEG recording of three partial seizures in a patient with the benign infantile convulsions associated with mild gastroenteritis.PURPOSE: In infants, benign convulsions can be triggered by febrile illness or mild diarrhea such as rotavirus gastroenteritis. The triggering mechanism of these convulsions is still unknown. In spite of several reports concerning clinical features, the ictal EEG recordings were rarely analyzed by a video-EEG monitoring system. To reveal a clue for the triggering mechanism of these convulsions, we analyzed the correlation of clinical manifestations and the EEG discharges during the ictal events and compared with previous reports. methods: The ictal EEG of a cluster of three afebrile convulsions associated with mild gastroenteritis was recorded by an EEG closed-circuit TV (EEG-CCTV) monitoring system in a 6-month-old healthy female infant. RESULTS: All seizures began as complex partial seizures (CPSs), which exhibited a motionless stare with or without leftward deviation of both eyes, and evolved to secondarily generalized tonic-clonic seizures (SGTCSs) for approximately 90 s. Each of three ictal discharges began from the right occipital, right centroparietotemporal, and left occipital regions, respectively. CONCLUSIONS: Although initiating sites of ictal discharges of benign infantile convulsions associated with mild gastroenteritis (BICE) were previously reported to be variable among patients, these results indicated that those differ among seizures even in a same infant.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
5/174. Coccygeal fracture, constipation, convulsion, and confusion: a case report of malignant hypertension in a child.Malignant hypertension is an unusual but well described cause of seizures in pediatrics. It is a medical emergency that must be recognized and emergently treated to prevent morbidity and mortality. In contrast to adults, hypertension in children is usually secondary to an underlying disease process. We present a complex case of hypertensive encephalopathy with seizures as the initial presentation of a pelvic mass, describe the initial work-up and stabilization and present an overview of the literature. review of the medical literature described only one similar presentation (1). Interestingly, acute symptoms in this patient may have been precipitated by use of an over-the-counter medication.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
6/174. An intrasylvian "fibroma" in a child with cystic fibrosis: case report.OBJECTIVE AND IMPORTANCE: Intracranial fibrous tumors are uncommon during childhood. An unusual case of benign intrasylvian "fibroma" that has remained clinically and radiographically stable more than 3 years after a subtotal resection is described. CLINICAL PRESENTATION: A 9-year-old girl with cystic fibrosis presented with new-onset focal seizures referable to a large calcified left sylvian fissure mass. INTERVENTION: An open biopsy with subtotal resection of the lesion revealed a benign process characterized by exuberant fibrocollagenous tissue intermeshed with chronic inflammatory cells and foreign body giant cells, encompassing islands of gliotic brain tissue. Immunohistochemical analysis showed staining for epithelial membrane antigen and reticulin within some of the spindle cells, although the majority were nonreactive. The majority of tumor cells exhibited staining for laminin; CD34 staining was absent. Ultrastructural studies were also suggestive of a fibroblastic rather than a meningothelial origin of the lesion, with elongated cells separated by abundant extracellular collagen. Although dense adherence of the mass to the pial surface and the middle cerebral artery vessels precluded a complete resection, the patient remains seizure-free without anticonvulsant therapy more than 3 years postoperatively with no evidence of growth of the lesion. CONCLUSION: The lesion in this patient bears morphological similarity to a rare group of tumors referred to as "intracerebral fibromas," although a variety of other rare mesenchymal neoplasms were also considered within the differential diagnosis. However, the absence of any definite neoplastic features, the finding of chronic inflammatory changes, and the lack of growth of the residual tumor during an extended follow-up interval indicate that the mass may represent either an extremely indolent neoplasm or a nonneoplastic process. The differential diagnosis of intracranial fibrous tumors is contrasted with that of the reported case.- - - - - - - - - - ranking = 0.3610748357482keywords = neoplasm (Clic here for more details about this article) |
7/174. Cerebral angiofibroma: case report.OBJECTIVE AND IMPORTANCE: Intracranial fibromatous tumors are very rare lesions, with few reported cases. CLINICAL PRESENTATION: We report the case of a 34-year-old male patient who experienced seizures resulting from a cystic lesion in the left occipital region, which remained unchanged for 11 years. After the seizures increased in number, magnetic resonance imaging revealed a large cyst with a tumor nodule. INTERVENTION: A left occipital craniotomy was performed, and the tumor was removed. Pathological studies, including immunohistochemical and ultrastructural analyses, indicated that this neoplasm was composed of fibrous and angiomatous components, and a diagnosis of cerebral angiofibroma was established. CONCLUSION: Cerebral and meningeal fibromas are rare neoplasms that differ from solitary fibrous tumors and fibrous meningiomas. When a number of prominent blood vessels are present in a cerebral or meningeal fibroma, a diagnosis of angiofibroma can be considered. It is possible that some nodular brain tumors that were previously described as meningioangiomatosis could be reclassified as cerebral or meningeal angiofibromas.- - - - - - - - - - ranking = 0.3610748357482keywords = neoplasm (Clic here for more details about this article) |
8/174. January 2000: 12 year old boy with recent onset seizures.A 12-year old boy presented with new onset of seizures and a CT scan showed a left frontal lobe tumor which was removed completely. Neuropathological examination showed a pleomorphic ganglion cell tumor with necrosi, and endothelial proliferation. The diagnosis was extraventricular atypical neurocytic neoplasm ("cystic ganglioneurocytoma").- - - - - - - - - - ranking = 0.1805374178741keywords = neoplasm (Clic here for more details about this article) |
9/174. Postcallosotomy seizure outcome in hemiconvulsion-hemiatrophy-epilepsy syndrome.Recently, three patients with hemiconvulsion-hemiplegia-epilepsy syndrome who underwent callosotomy were monitored for more than four years. All patients had atrophy of the right brain hemisphere with left hemiparesis and seizures. Two cases were probably the result of traumatic intracranial hemorrhage and one was due to an unknown cause. Wada tests were done in cases 1 and 2, which showed spared motor function of the atrophic hemisphere, supporting the choice of callosotomy instead of hemispherectomy. Patient 1 had atypical absence seizures and asymmetric generalized tonic seizures before surgery, the latter of which decreased by about 60% after callosotomy. Patient 2 had simple partial seizures of the motor type and complex partial seizures, the latter of which were also induced by touch (somatosensory-induced reflex epilepsy). This patient's complex partial seizures disappeared completely, but the simple partial seizures remained unchanged. Patient 3 had generalized tonic seizures, simple partial seizures of the sensory type and complex partial seizures. After surgery, the frequency of the generalized tonic seizures decreased more than 90%. The simple partial seizures of the sensory type remained unchanged. There were two new types of seizures after surgery, simple partial seizures of the motor type and brief generalized myoclonic jerks. All patients had significant reductions in numbers of seizures of more than 50%.- - - - - - - - - - ranking = 3keywords = complex (Clic here for more details about this article) |
10/174. Transitory and permanent visual field defects induced by occipital lobe seizures.Visual field defects are rarely associated with epilepsy. We report two patients with a long history of cryptogenetic occipital epilepsy. Both patients suffer complex partial crises accompanied by concentric reduction of the visual field followed, in the first one, by a prolonged left homonymous hemianopsia, and in the second one, by a permanent right inferior quadrantopsia. Occipital and occipito-temporal epileptic activity has been registered between seizures in both patients, and in one patient also during the seizure itself. Differential diagnosis has been considered, especially with migraine.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
