1/144. Transient paralytic attacks of obscure nature: the question of non-convulsive seizure paralysis.Eleven patients with transient paralytic attacks of obscure nature are described. paralysis could involve face or leg alone, face and hand, or face, arm and leg. The duration varied from two minutes to one day. Four patients had brain tumors, six probably had brain infarcts, and one a degenerative process. The differential diagnosis included TIAs, migraine accompaniments, and seizures. In the absence of good evidence for the first two, the cases are discussed from the standpoint of possibly representing nonconvulsive seizure paralysis (ictal paralysis, inhibitory seizure paralysis or somatic inhibitory seizure). Because of the difficulty in defining seizures as well as TIAs and migraine in their atypical variations, a firm conclusion concerning the mechanisms of the spells was not attained. Two cases of the hypertensive amaurosis-seizure syndrome have been added as further examples of ictal deficits.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/144. Progressive ponto-bulbar palsy with deafness. A clinico-pathological study.Progressive ponto-bulbar palsy with deafness is a rare disease. It seems to be an abiotrophic process with autosomal recessive inheritance in most instances. Only one autopsy case had been briefly described (Lelong et al., 1941). The clinical features and the pathological findings of a new case are reported. The structures primarily involved are the grey matter of the brain stem and the spinal cord, including to some extent the optic tracts and most of the fiber tracts in the brain stem with exception of the pyramidal tracts.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
3/144. Neuro-ophthalmologic manifestations of Maffucci's syndrome and Ollier's disease.patients with Ollier's disease (multiple skeletal enchondromas) and Maffucci's syndrome (multiple enchondromas associated with subcutaneous hemangiomas) may develop skull base chondrosarcomas or low-grade astrocytomas as a delayed consequence of these disorders. We report three patients with Ollier's disease and Maffucci's syndrome who had diplopia as the initial manifestation of intracranial tumors. Since patients with Maffucci's syndrome and Ollier's disease are at risk for the delayed development of brain and systemic neoplasms, neuroophthalmologists must be aware of the need for long-term surveillance in patients affected by these conditions.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
4/144. Pontine cryptococcoma in a nonimmunocompromised individual: MRI characteristics.The case of a pontine cryptococcoma in a nonimmunocompromised, previously healthy 16-year-old boy is presented. The patient had slowly progressive brainstem signs with right cranial nerves V, VII, and VIII palsies, and contralateral corticospinal and spinothalamic deficits. Magnetic resonance images (MRI) revealed, within the right pons, a 1-cm diameter round mass lesion, hypointense on T1-weighted images, hyperintense on T2-weighted images, and with rim enhancement after infusion of gadopentetate dimeglumine. This is the only report of the MRI findings in an isolated pontine cryptococcoma in an immunocompetent patient. Early recognition of this specific MRI pattern is essential, because complete recovery can be achieved with prompt antifungal treatment.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
5/144. Bilateral trochlear nerve palsy associated with cryptococcal meningitis in human immunodeficiency virus infection.This is the report of a case of bilateral trochlear nerve palsy secondary to cryptococcal meningitis in a 34-year-old woman with acquired immune deficiency syndrome. Based on clinical and neuroradiologic findings, it is concluded that in the present case, a postinflammatory shrinking of the arachnoid has stretched the fourth cranial nerves at their point of emergence from the dorsal surface of the brainstem.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
6/144. Palatal tremor, progressive multiple cranial nerve palsies, and cerebellar ataxia: a case report and review of literature of palatal tremors in neurodegenerative disease.We describe a patient with an unusual clinical presentation of progressive multiple cranial nerve palsies, cerebellar ataxia, and palatal tremor (PT) resulting from an unknown etiology. magnetic resonance imaging showed evidence of hypertrophy of the inferior olivary nuclei, brain stem atrophy, and marked cerebellar atrophy. This combination of progressive multiple cranial nerve palsies, cerebellar ataxia, and PT has never been reported in the literature. We have also reviewed the literature of PT secondary to neurodegenerative causes. In a total of 23 patients, the common causes are sporadic olivopontocerebellar atrophy (OPCA; 22%), Alexander's disease (22%), unknown etiology (43.4%), and occasionally progressive supranuclear palsy (4.3%) and spinocerebellar degeneration (4.3%). Most patients present with progressive cerebellar ataxia and approximately two thirds of them have rhythmic tremors elsewhere. Ear clicks are observed in 13% and evidence of hypertrophy of the inferior olivary nucleus in 25% of the patients. The common neurodegenerative causes of PT are OPCA/multiple system atrophy, Alexander's disease, and, in most of them, the result of an unknown cause.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
7/144. Guglielmi detachable coil treatment of a partially thrombosed giant basilar artery aneurysm in a child.We report a partially thrombosed giant of the aneurysm basilar artery with prominent mass effect, diagnosed in an 11 year-old child who presented with neurological deficits due to brain stem compression. After the patent portion of the aneurysm was embolised with Guglielmi detachable coils, remarkable clinical improvement occurred. angiography demonstrated complete occlusion of the aneurysm and MRI revealed dramatic shrinkage of the aneurysm at 6-month and 1-year follow-up.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
8/144. Bilateral phrenic neuropathy as a presenting feature of multifocal motor neuropathy with conduction block.Diaphragmatic paralysis has previously been reported as a result of diverse pathologic processes involving the peripheral nervous system. We report the clinical history, physical findings, and antibody profile of an atypical case of multifocal motor neuropathy with conduction block initially presenting with respiratory failure secondary to bilateral phrenic neuropathy.- - - - - - - - - - ranking = 0.65777640348283keywords = nervous system (Clic here for more details about this article) |

10/144. Asymmetric sweating in a child with multiple sclerosis.A 10-year-old male with multiple sclerosis complained of excessive sweating on the right side of the forehead and shoulder on relapse 3 months after the onset of multiple sclerosis. Because the neurologic evaluation revealed no abnormalities in the sudomotor function, it is likely that the hyperhidrosis resulted from a lesion in the central or preganglionic sympathetic nervous system. magnetic resonance imaging demonstrated a high-intensity lesion involving the left hypothalamus on T(2)-weighted imaging. Thus hypothalamic involvement might be the reason for the hyperhidrosis in this patient.- - - - - - - - - - ranking = 0.65777640348283keywords = nervous system (Clic here for more details about this article) |
