Clinical, neuropsychological and neuropsychophysiological data (Q-EEG, ERPs and CNV/RT activity) were obtained from 24 patients who had more or less severe presenile primary cognitive decline without depression, and compared with similar data from 10 age-matched healthy volunteers (mean age, 59.4 years). All of the patients (15 M and 9 F; mean age 59.6(More)
Parry-Romberg syndrome or progressive facial hemiatrophy (PFH) is a rare disease of unknown etiology characterized by atrophy of the skin and subcutaneous tissue on one side of the face. The authors present the case of a 32-year-old woman with PFH who had migraine and an intracranial aneurysm. The findings support the hypothesis that the disease could be(More)
The sensitivities and predictive values of visual, somatosensory, and brain auditory evoked potentials (EPs), cerebrospinal fluid oligoclonal banding (CSF-OB) and magnetic resonance imaging (MRI) were evaluated for the early diagnosis of clinically definite multiple sclerosis (CDMS). Paraclinical evidence of asymptomatic lesions allows a diagnosis of CDMS.(More)
Among CNS tumors, intracranial melanomas represent a subject of interest for neurooncologists and neurosurgeons because clinical and radiological patterns of these tumors can mimic the presence of meningiomas, and in spite of their malignant behavior they can be satisfactorily treated. In the present report we describe a new case of primary intracranial(More)
OBJECTIVE The aim of our study was to describe the neuroradiologic features of 12 patients with ataxia-telangiectasia (A-T), a degenerative multisystemic autosomal recessive hereditary disorder with onset in childhood. Clinical features include cerebellar ataxia, oculocutaneous telangiectasias, and recurrent bronchopulmonary infections. Patients present(More)
PURPOSE To investigate signal alterations in the thalamic lateral geniculate bodies of blind patients compatible with transsynaptic degeneration of these nuclei caused by pregeniculate or postgeniculate interruption of the visual pathway. METHODS Six patients were selected from a group of blind children in our care. Four had cerebral palsy caused by(More)
Intrahepatic cholangiocarcinoma (ICC) is a rare life-threatening disease, whose only treatment with potential for cure is surgical resection. However, only 27% of patients at most are suitable for surgery when first diagnosed. For patients with unresectable disease, therapeutic options are chemotherapy or chemoradiation. We evaluated the feasibilty and(More)
BACKGROUND AND AIM Carotid artery disease may cause both thromboembolism and cerebral blood flow disturbances, particularly in subjects with impaired hemodynamic compensatory mechanisms. The aim of this study was to evaluate by transcranial Doppler (TCD) the hemodynamic changes induced by CO2 and L-Arginine stimulation in a selected population with severe(More)
The aim of this study was to investigate the effects of disruption on the warning auditory S1-elicited ERP and CNV complexes recordable on the site and on remote ipsilateral apparently normal anatomo-functionally interconnected brain regions. These effects in some cases showed aspects of a probable diaschisis-like phenomenon, due to resections of extensive(More)
A rare case of diffuse leptomeningeal melanosis presenting with symptoms of spinal cord compression due to the presence of anterolateral arachnoid cyst and treated with Spetzler's drainage system is reported. The diagnosis of diffuse melanosis of the leptomeninges is rarely possible during life. In the present case MRI was of great help in the definition of(More)
