Two cases of nontraumatic cerebrospinal fluid rhinorrhea were presumed to be an indirect manifesta tion of brain tumor. One patient had a parietal convexity meningioma and the other a cerebello pontine angle neurinoma. Following excision of the tumors these patients spontaneously developed cerebrospinal fluid rhinorrhea, which disappeared after the repair of fistulas at the base of the frontal ...
Intracranial ependymal cysts are rare, congenital, benign lesions. These commonly occur in the supratentorial regions and usually generate no symptoms. The cerebellopontine angle (CPA) is an extremely rare site for ependymal cysts. Furthermore, there are no previous reports of CPA ependymal cysts related to syncope. We report a case of ependymal cyst in the left CPA with syncope. The patient un...
The behavioral phenomenon of blocking indicates that the informational relationship between the conditioned stimulus and the unconditioned stimulus is essential in classical conditioning. The eyeblink conditioning paradigm is used to describe a neural mechanism that mediates blocking. Disrupting inhibition of the inferior olive, a structure that conveys unconditioned stimulus information (airpu...
The clinical syndrome of a 65-year-old patient with a slit-shaped right-sided meso-diencephalic lesion was analysed. A cerebellar syndrome with limb-kinetic ataxia, intention tremor and hypotonicity in all extremities as well as ataxic dysarthria was found. The disruption of the two cerebello-(rubro)-thalamic pathways probably explained the signs of bilateral cerebellar dysfunction. The uncross...
Recent developments in magnetic resonance imaging have provided further insights into the pathophysiology of movement disorders including dystonias and Tourette syndrome. Both structural and functional abnormalities have been described in dystonic patients, with a number of genotype-phenotype correlations. Interactions between the cerebello-thalamo-cortical and basal ganglia-cortex networks pla...
Simultaneous occurrence of cardiac and central nervous system tumors have been rarely reported. A 23 years male presented to us with right cerebello-pontine (CP) angle symptoms and signs. Cranial imaging showed a mass lesion in the right pons infiltrating into the right and middle cerebellar peduncles. There was also a cardiac-atrial septal mass. The brainstem lesion was found to be a non-Hodgk...
