1/297. 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 = 1keywords = injury (Clic here for more details about this article) |
2/297. 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 = 1583.2894278386keywords = carotid artery, carotid, artery (Clic here for more details about this article) |
3/297. 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 = 0.43013306904406keywords = trauma (Clic here for more details about this article) |
4/297. 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 = 47.606471336585keywords = artery (Clic here for more details about this article) |
5/297. Moyamoya syndrome in a patient with congenital human immunodeficiency virus infection.A 10-year-old boy with congenital human immunodeficiency virus (hiv) infection developed recurrent episodes of left hemiparesis at age 7 years. The progression of his disease was followed by computed tomography, magnetic resonance imaging, magnetic resonance angiography, and cerebral angiography. The series of images showed progressive stenosis of both carotid arteries at the suprasellar origin with involvement of his anterior and middle cerebral arteries, while prominent collateral vessels developed from his external carotid supply through ophthalmic and middle meningeal arteries. The pattern of cerebrovascular disease is consistent with moyamoya syndrome. We suggest that further studies on the pathophysiology of cerebrovascular disease in patients with hiv could be helpful in understanding the cause of moyamoya disease as well. Also, with the various advances in treatment of hiv, neurovascular complications could be seen more frequently as the long-term survival in these patients improves.- - - - - - - - - - ranking = 200.21143760838keywords = carotid (Clic here for more details about this article) |
6/297. moyamoya disease showing atypical angiographic findings--two case reports.A 7-year-old boy and a 10-year-old girl presented with moyamoya disease showing atypical angiographic findings. In these cases, the internal carotid artery (ICA) had a tapering occlusion just distal to the origin of the ophthalmic artery, whereas the top of the ICA was not occluded and was retrogradely supplied through the posterior communicating artery from the posterior circulation. Surgical treatment resolved the symptoms in both patients. moyamoya disease may include a number of variant types not showing all the characteristic angiographic findings of moyamoya disease.- - - - - - - - - - ranking = 345.22176836967keywords = carotid artery, carotid, artery (Clic here for more details about this article) |
7/297. 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 = 2.107533267261keywords = injury, trauma (Clic here for more details about this article) |
8/297. 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 = 111.08176645203keywords = artery (Clic here for more details about this article) |
9/297. 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 = 0.5keywords = injury (Clic here for more details about this article) |
10/297. 'Fou rire prodromique' as the heralding symptom of lenticular infarction, caused by dissection of the internal carotid artery in a 12-year-old boy.A 12-year-old, right-handed boy experienced a pathological fit of laughter before a sudden right hemiplegia. magnetic resonance imaging showed a left basal ganglia infarction, induced by a left internal carotid dissection. Arteriography revealed an underlying fibromuscular dysplasia. This case study demonstrates that cerebral artery dissection can occur in children and that a basal ganglia infarction may be preceded by pathological laughter called 'fou rire prodromique'. The clinical and anatomical relationship of this paroxysmal event are discussed.- - - - - - - - - - ranking = 1369.9110258308keywords = carotid artery, carotid, artery (Clic here for more details about this article) |
