1/437. Biofeedback training to overcome poststroke foot-drop.The technique has exciting potential for elderly hemiplegic patients, even those who are confined to a nursing home. There are limiting factors, of course; the method is time-consuming and the initial outlay for equipment is high. But the rewards can be well worth the time, effort, and cost involved. The recovery potential of some geriatric patients after a cerebrovascular accident may seem bleak because of multiple disabilities, e.g., paralysis, delayed reflexes, aphasia. Fortunately, these disorders do not necessarily decree failure of biofeedback training. Neither does advanced age. The strongest component in success is motivation. A case in point is the 82 year old woman described here who had been hemiparetic for seven years. With biofeedback training, she gained--and maintained--muscle strength.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
2/437. MR and CT imaging in the Dyke-Davidoff-Masson syndrome. Report of three cases and contribution to pathogenesis and differential diagnosis.Cerebral hemiatrophy or Dyke-Davidoff-Masson syndrome is a condition characterized by seizures, facial asymmetry, contralateral hemiplegia or hemiparesis, and mental retardation. These findings are due to cerebral injury that may occur early in life or in utero. The radiological features are unilateral loss of cerebral volume and associated compensatory bone alterations in the calvarium, like thickening, hyperpneumatization of the paranasal sinuses and mastoid cells and elevation of the petrous ridge. The authors describe three cases. Classical findings of the syndrome are present in variable degrees according to the extent of the brain injury. Pathogenesis is commented.- - - - - - - - - - ranking = 9309.6885422773keywords = hemiparesis, paresis (Clic here for more details about this article) |
3/437. Non-surgical treatment of meningioma: a case report and review.A woman initially presented with a right hemiparesis and subsequently underwent subtotal resection of a left parietal meningioma arising from the lateral wall of the sagittal sinus. She again presented 18 months after surgery with a hemiparesis and repeat MRI showed tumour spreading into the sagittal and the transverse sinuses. She had a therapeutic abortion at 8 weeks gestation 3 weeks prior to her representation. gestrinone, a synthetic steroid and an antiprogesterone was commenced. Two months later she stopped her medication and is asymptomatic at 16 months. A follow-up MRI revealed that the tumour had shrunk dramatically. This case is the first of its kind with tumour size reduction to less than 20%. We feel that the future of meningioma treatment will be multi-disciplinary and non-surgical options should be considered.- - - - - - - - - - ranking = 18619.377084555keywords = hemiparesis, paresis (Clic here for more details about this article) |
4/437. A case of the subacute brainstem encephalitis.A case of brainstem encephalitis of undetermined etiology is reported in 66-year-old woman who had a sudden onset of illness with left abducens palsy, nystagmus and ataxia. The symptoms progressed to complete paralysis of eye movements, dysphagia and left hemiparesis with generalized hyperreflexia. Examination of CSF, CT scan and MRI of the brain were normal. The patient died 4 months after onset of disease. Neuropathologic study disclosed in the brainstem numerous perivascular and nodular inflammatory cell infiltrations composed predominantly of lymphocytes T and B. Most intensive inflammation concerned midbrain and pontine tegmentum and to a lesser degree medulla oblongata, pontine nuclei and cerebellar nuclei. basal ganglia, cerebral and cerebellar cortex were unaffected. Neuropathological finding was reminiscent of brainstem encephalitides related to viral infection or to paraneoplastic syndrome. However, HSV-1, EBV, and CMV antigens were not detected by immunohistochemistry, as well as evidences of malignancy were not present in this case.- - - - - - - - - - ranking = 9309.6885422773keywords = hemiparesis, paresis (Clic here for more details about this article) |
5/437. Surgical treatment of internal carotid artery anterior wall aneurysm with extravasation during angiography--case report.A 54-year-old female presented subarachnoid hemorrhage from an aneurysm arising from the anterior (dorsal) wall of the internal carotid artery (ICA). During four-vessel angiography, an extravasated saccular pooling of contrast medium emerged in the suprasellar area unrelated to any arterial branch. The saccular pooling was visualized in the arterial phase and cleared in the venophase during every contrast medium injection. We suspected that the extravasated pooling was surrounded by hard clot but communicated with the artery. Direct surgery was performed but major premature bleeding occurred during the microsurgical procedure. After temporary clipping, an opening of the anterior (dorsal) wall of the ICA was found without apparent aneurysm wall. The vessel wall was sutured with nylon thread. The total occlusion time of the ICA was about 50 minutes. Follow-up angiography demonstrated good patency of the ICA. About 2 years after the operation, the patient was able to walk with a stick and to communicate freely through speech, although left hemiparesis and left homonymous hemianopsia persisted. The outcome suggests our treatment strategy was not optimal, but suture of the ICA wall is one of the therapeutic choices when premature rupture occurs in the operation.- - - - - - - - - - ranking = 9309.6885422773keywords = hemiparesis, paresis (Clic here for more details about this article) |
6/437. magnetic resonance angiography of primary varicella vasculitis: report of two cases.Two patients with onset of hemiparesis 3 weeks following primary varicella infection demonstrated contralateral temporal lobe and basal ganglia infarctions on magnetic resonance imaging. In both cases, magnetic resonance angiography (MRA) was performed and demonstrated flow abnormalities ipsilateral to the infarcts. Digital subtraction angiography was performed in one case; however, the findings were significantly less conspicuous than those of the MRA. MRA proved to be sensitive to the diagnosis of varicella-induced vasculitis in two consecutive cases and provided a noninvasive means of following the progression of the disease process in response to therapy.- - - - - - - - - - ranking = 9309.6885422773keywords = hemiparesis, paresis (Clic here for more details about this article) |
7/437. Familial hemiplegic migraine with cerebellar ataxia and paroxysmal psychosis.Familial hemiplegic migraine is a rare autosomal dominant disorder associated with stereotypic neurologic aura phenomena including hemiparesis. So far two chromosomal loci have been identified. Families linked to the chromosome 19 locus display missense mutations within the CACNL1A4 gene. Here we report on a family with familial hemiplegic migraine and cerebellar ataxia with recurrent episodes of acute paranoid psychosis with anxiety and visual hallucinations associated with migraine attacks. Based on the clinical and haplotype evidence indicating linkage to chromosome 19 in this family, we hypothesize that a dysfunction of the mutated calcium channel may be involved not only in the development of hemiplegic migraine but also in the acute psychotic episodes observed in these patients.- - - - - - - - - - ranking = 9309.6885422773keywords = hemiparesis, paresis (Clic here for more details about this article) |
8/437. Reversible cerebral ischemia in patients with pheochromocytoma.Cerebral ischemia and symptoms of stroke can occur as a rare manifestation in patients with pheochromocytoma. We describe a 45-year-old woman who was admitted because of a right-sided hemiparesis due to an ischemic lesion in the left hypothalamus. The clinical diagnosis of a pheochromocytoma was proven by highly elevated urinary catecholamines and confirmed histologically after operation. The successful removal of the tumor led to the almost complete recovery of the neurological deficiencies. It is of vital importance to know this atypical presentation of pheochromocytoma. The diagnosis of pheochromocytoma should be suspected in patients with focal cerebral symptoms, particularly in the presence of intermittent hypertension or other paroxysmal symptoms suggestive of pheochromocytoma.- - - - - - - - - - ranking = 9309.6885422773keywords = hemiparesis, paresis (Clic here for more details about this article) |
9/437. Localized scleroderma associated with progressing ischemic stroke.We present a 73 year-old Japanese woman with localized scleroderma involving the right side of the scalp accompanied by continuous tingling pain, who developed insidiously progressive left hemiparesis. In magnetic resonance imaging of the brain, an infarct first appeared in the watershed region of the right middle cerebral artery territory and subsequently extended to deep white matter accompanied by scattered hemorrhages. Focal stenosis in the M2 portion of the right middle cerebral artery was revealed on magnetic resonance angiography, and the distal vessels were only shown faintly. A biopsy specimen from the sclerotic scalp lesion showed obvious thickening of vessel walls and mild mononuclear cell infiltration. We believe that the progressing ischemic stroke was caused by hemodynamic disturbances from localized sclerotic obstruction of the middle cerebral artery, with an autoimmune pathogenesis.- - - - - - - - - - ranking = 9309.6885422773keywords = hemiparesis, paresis (Clic here for more details about this article) |
10/437. Posterior fossa epithelial cyst: case report and review of the literature.A 49-year old woman with progressive cranial nerve signs and hemiparesis was found at MR imaging and at surgery to have a cyst at the foramen magnum. immunohistochemistry and electron microscopy showed an epithelial cyst of endodermal origin. MR findings were of an extraaxial mass, with short T1 and T2 times. Unless immunohistochemistry and electron microscopy are used in the final diagnosis of such cysts, all posterior fossa cysts lined by a single layer of epithelium should be described simply as epithelial cysts.- - - - - - - - - - ranking = 9309.6885422773keywords = hemiparesis, paresis (Clic here for more details about this article) |
