    ABSTRACT: We report the entire course of a case of thrombosis of the venous sinuses, very probably caused by contraceptive pill use, documented by MR imaging. MRI appears to be the examination of choice in such cases.

    ABSTRACT: Risk factors, neurological, neuroradiological and ophthalmological features of 13 cases of acute pseudotumor cerebri were studied. After a 53-month period of mean follow-up, ophthalmological complications were taken into consideration: one patient (8%) showed unilateral optic atrophy with complete loss of vision, another subject complained of visual field constriction, and a third one of transient horizontal diplopia. Papilledema, which was present in 100% of the patients in the acute phase, persisted in 62%.

    ABSTRACT: We report a case of oculoskeletal myopathy with abnormal mitochondria in which the chief clinical feature was ophthalmoplegia. Muscle weakness was mild and there were no retinal or cerebellar abnormalities, no deafness and no cardiac defects. The muscle biopsy specimen revealed subsarcolemmal mitochondrial aggregates and ragged red fibers. Electronmicroscopy showed that the aggregates were made up of mitochondria of variable size with structural abnormalities of the cristae and crystalloid inclusions. We believe that this oculoskeletal myopathy is distinct from Kearn-Sayre syndrome.

    ABSTRACT: A retrospective study of all admissions to the University of Modena Neurological Department from 1976-1986; 51 cases of amyotrophic lateral sclerosis (ALS) were found. ALS mean annual incidence was 0.78/100,000 inhabitants, while prevalence was 2.35/100,000. Mean age at onset was 61.43 years, mean and median duration of illness were, respectively, 28.83 and 24.5 months, and survival at 5 years post-onset was 24.4%. A tendency to higher incidence and prevalence of ALS in the ceramic district, when compared with those of the rest of the province was found. However, the small number of cases did not allow any conclusive statistical correlation between environmental exposure to lead and frequency of ALS.

    ABSTRACT: We present a case of herpes zoster (HZ) with some uncommon features, namely lumbar localization and muscle weakness with a distribution different from the site of cutaneous eruptions and sensory deficits. Spread of HZ virus from sensory ganglion to anterior horn cells seems the only possible explanation of these clinical features. Urinary retention and CSF data confirm the hypothesis of HZ myelitis.

    ABSTRACT: Ataxic hemiparesis is a relatively frequent clinical syndrome in which motor and cerebellar deficits on the same side are associated. A prospective study conducted on 27 patients who displayed these vascular symptoms confirms that the areas crucial to the onset of this syndrome are the capsular region (posterior limb-corona radiata) and the upper basis pontis.

    ABSTRACT: A total of 66 patients with supratentorial ischemic infarct underwent serial CT scans in order to study the relationship between CT images and clinical evolution of the infarct. Little information of prognostic value is given by CT in patients with slight neurological deficits, whereas it enables factors with a negative influence on the prognosis to be identified in patients with moderate to severe deficits.

    ABSTRACT: From 1978 to 1980, thirty-one patients aged forty years or less, had cerebral ischemic events as TIA, RIND or complete stroke. These patients have been studied, both clinically and with laboratory tests to assess the most common causes of their disorder. It was found that hypertension, excess smoking, diabetes and disorders of the lipid metabolism are the most common causes of the atherosclerosis, which plays a role in enhancing ischemic cerebro-vascular accidents during youth. The detection as well as the localization of the site of the ischemic lesions was difficult; only in six out of the seventeen patients examined it was possible to show angiographically a stenosis of one cerebral vessel. Comparison between the 31 patients and 31 subjects of the same age without clinical symptoms or neurological signs, showed a significant incidence of causes of atherosclerosis in the control subjects. In view of the limited number of controls it was not possible to predict a clearcut prognosis.

    ABSTRACT: Foix-Chavany-Marie syndrome is characterized by diplegia involving the face, the pharynx, the tongue and the masticatory muscles, with automatic-voluntary dissociation due to vascular damage of both operculi. The prognosis is usually good for life expectancy. The authors describe a 46-year-old man in whom one operculum was destroyed because of a birth trauma, the other one was injured by an ischemic infarct in the territory of the middle cerebral artery. The clinical correlations to the site of the lesions are discussed. They confirm the diagnostic value of CT scan in evaluating this syndrome.

    ABSTRACT: A right-handed patient with no family history of either neurological disorders or of left-handedness was affected by crossed aphasia due to a focal hemorrhagic lesion in the right hemisphere at the level of the basal ganglia. The CAT-scan revealed the site of the brain change. Our case is uncommon in that the aphasia. Assessed by neuropsychological tests, was associated with impairment of right functions such as visual and spatial cognition. Thus he does not fit the classic description of crossed aphasia, exhibiting instead language disorders similar to those following deep brain lesions. Various hypotheses were considered in attempting to explain the pathogenesis of our neurological data, none of which proved adequate to account for all the reported findings.
