1/304. Acquired and isolated asymmetrical palatal palsy.Benign acquired and isolated asymmetrical palatal palsy is a rare condition in childhood. We report on three cases. Typical features include: sudden onset, abnormality of the palatal components of speech (rhinolalia), nasal escape of fluids from the ipsilateral nostril. It is supposed to be caused by viral infection, but attempts at viral isolation were unsuccessful. Complete spontaneous recovery is usual, taking a few weeks. Our paper seems to be the first report of magnetic resonance imaging of the brain in this condition. It did not disclose any abnormalities in the 2 cases in which it was performed.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/304. 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 = 3.4935862183503keywords = brain injury, brain, injury (Clic here for more details about this article) |
3/304. 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 = 9keywords = brain (Clic here for more details about this article) |
4/304. On some neurobiological and cultural-anthropological aspects of the contralateral-neglect syndrome.Contralateral neglect is a frequent clinical syndrome which can be provoked by lesions in several brain areas (primarily inferior parietal and frontal) and includes symptoms of motor and perceptual negligence of both real and imaginative contralateral hemi-space. Attentional and representative theories attempting to explain neglect are presently the most popular. This paper analyzes two cases of neglect patients. Paying attention especially to their reading defects, a possible role of the persons with contralateral neglect is proposed in the development of script. Other neurobiological and cultural-anthropological questions arising from the analysis of these cases are also discussed.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
5/304. Traumatic aphasia in children: a case study.Traumatic aphasia in children has been recognized as a distinct clinical pathology, differing from adult aphasia in symptomatology and course of recovery. The upper limit for complete recovery has been identified as age 10. However, there is a paucity of literature documenting recovery of children with traumatic aphasia. It is apparent that definitive statements of the upper age limit for complete recovery from traumatic aphasia in children cannot be made at this time. This article reviews the literature concerning traumatic aphasia and presents case information of a 10-year-old traumatic aphasic girl seen at the North texas State University speech and hearing Center. The design, execution, and assessment of therapeutic interaction and the observed language abilities of the client are reported.- - - - - - - - - - ranking = 0.0083130363742623keywords = trauma (Clic here for more details about this article) |
6/304. 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 = 1keywords = brain (Clic here for more details about this article) |
7/304. Neurologic compromise after an isolated laminar fracture of the cervical spine.STUDY DESIGN: Report of a rare fracture of the cervical spine. OBJECTIVES: To illustrate the importance of the cervical spinolaminar line in the diagnosis of this unusual injury and to comment on appropriate investigations, management, and outcome. SUMMARY OF BACKGROUND DATA: Laminar fractures of the cervical spine are uncommon and are often missed. They usually occur after a hyperextension injury. It is unusual for these injuries to cause neurologic compromise. The injury reported here differs in that it was a result of direct trauma to the posterior aspect of the neck, and there was a significant neurologic deficit. methods: The clinical findings, roentgenographic appearance, treatment, complications, and follow-up assessment are presented and discussed. RESULTS: Initial neurologic examination revealed a right hemiparesis. Radiographs showed disruption of the spinolaminar line at C5 and a computed tomography scan revealed a fracture of the lamina of C5 with spinal canal encroachment. Management included high-dose corticosteroid administration and a posterior spinal decompression. The patient's initial postoperative course was complicated by acute pulmonary edema, which responded well to intravenous furosemide and ventilation. Follow-up assessment showed significant neurologic improvement. CONCLUSIONS: The satisfactory outcome in the case of this rare injury was the result of a prompt, accurate diagnosis and appropriate management.- - - - - - - - - - ranking = 0.34995817232431keywords = injury, trauma (Clic here for more details about this article) |
8/304. Aggravation of brainstem symptoms caused by a large superior cerebellar artery aneurysm after embolization by Guglielmi detachable coils--case report.An 81-year-old male presented with right oculomotor nerve paresis and left hemiparesis caused by a mass effect of a large superior cerebellar artery aneurysm. Endovascular treatment was performed using Guglielmi detachable coils. The patient subsequently suffered aggravation of the mass effect 3 weeks after the embolization. Bilateral vertebral artery occlusion was performed, which decreased the cerebral edema surrounding the aneurysm, but his neurological symptoms did not improve. Parent artery occlusion is recommended as the first choice of treatment for an unclippable large or giant aneurysm causing a mass effect on the brainstem.- - - - - - - - - - ranking = 5keywords = brain (Clic here for more details about this article) |
9/304. Weber's syndrome secondary to subarachnoid hemorrhage.BACKGROUND: Since a large intracranial hemorrhage is a space-occupying mass, it may cause the brain to shift, resulting in neurologic deficits both at the location of the bleeding and at a site distal to the hemorrhage. A parietal lobe hemorrhage may push the brain downward, causing the uncus of the temporal lobe to herniate through the tentorial notch, compressing the midbrain. The signs of parietal lobe damage, uncal herniation, and several midbrain syndromes that effect ocular motility are discussed. CASE REPORT: A 66-year-old Hispanic man came to us with a history of a subarachnoid hemorrhage that involved the right parietal lobe. Several signs of damage to both the right parietal lobe and midbrain were evident, including an ipsilateral third nerve paresis with contralateral hemiplegia, Weber's syndrome. CONCLUSION: A patient who survives a subarachnoid hemorrhage may demonstrate permanent residual neurologic deficits subsequent to the acute event. The presentation is particularly complex when the hemorrhage is large and damage occurs at multiple locations. Damage at the level of the midbrain is evident when the findings include Weber's syndrome, which is one of several syndromes that involves the oculomotor nerve.- - - - - - - - - - ranking = 6keywords = brain (Clic here for more details about this article) |
10/304. hemiplegia hypoglycaemia syndrome.We report the case of a 83-year-old man who presented to the emergency department with hypoglycaemia resembling a cerebrovascular accident. Hypoglycaemic hemiparesis is an under-recognized manifestation of hypoglycaemia. If not recognized and treated promptly, hypoglycaemia may cause irreversible central nervous system injury; it rarely results in death. It is imperative that emergency physicians consider hypoglycaemia in all patients with coma in spite of focal neurological deficit even when the findings seem to be explained initially by other aetiologies.- - - - - - - - - - ranking = 0.086969978307687keywords = injury (Clic here for more details about this article) |
