    Notes: Summary The early CT finding of an hyperdensity of a portion of the middle cerebral artery Hyperdense Middle Cerebral Artery Sign (HMCAS), in patients with supratentorial stroke, is often indicative of an embolic occlusion. Aim of this study was to verify the incidence and reliability of the HMCAS and its possible correlation with early CT findings and with the extent of late brain damage. We studied 36 patients presenting with symptoms of stroke in the MCA territory, by means of CT and angiography performed respectively within 4 and 6 hours. Follow-up CT scans were then obtained after one week and three months from the ischemic event. The HMCAS was present in 50% of our patients and in this group it always correlated positively with the angiographic finding of occlusion. The same group presented a high incidence of erly CT hypodensity (88%). Finally the presence of HMCAS might be considered a negative prognostic sign for the development of extensive brain damage.

    Correlation between MRI findings and long-term outcome in patients with severe brain trauma (2000)

    Notes: Abstract Our aim was to relate MRI findings in patients with severe traumatic brain injury (TBI) to clinical severity and long-term outcome. We studied 37 patients with severe TBI, who were submitted to clinical assessment for disability and cognition and to MRI 60–90 days after trauma. Clinical assessment was also performed 3, 6 and 12 months later. The number and volume of lesions in various cerebral structures were calculated semiautomatically from FLAIR and fast field-echo images. Possible correlations between total and regional lesion volume and clinical deficits were then investigated. The frontal and temporal lobes were most frequently involved. Total lesion volume on FLAIR images correlated significantly with clinical outcome, whereas that on FFE images did not. Regional analysis showed that FLAIR lesion volume in the corpus callosum correlated significantly with scores on disability and cognition scales at the first clinical assessment. FLAIR lesion volume in the frontal lobes correlated significantly with clinical scores 1 year later.

    Cavernous angiomas of the nervous system in Italy: clinical and genetic study (2000)
    Springer
    Neurological sciences 21 (2000), S. 129-134

    Notes: Abstract We performed a clinical and genetic study of patients affected by cavernous angiomas (CA) of the nervous system. We examined initial signs and symptoms in sporadic and familial cases. We obtained clinical, neuroimaging and genetic data on 15 Italian patients with CA of the nervous system with positive, doubtful or apparently negative family history. Genetic markers surrounding three different gene regions (7q, 3q and 7p) were analysed. In one small family, genetic linkage was consistent with all chromosome loci. In another family with the unusual association of cerebral and spinal CA, linkage with chromosome 7q and, likely, 7p was excluded, while linkage with locus 3q was possible. Our results indicate that Italian families with CA may show genetic heterogeneity. Non-specific and subtle onset symptoms hide the presence of CA within families. Patients with multiple CA may have silent cerebral lesions confirming the low penetrance of clinical signs in spite of radiological ones.

    Description / Table of Contents: Sommario 31 pazienti con segni clinici di un processo degenerativo cerebellare sono stati sottoposti a tomografia computerizzata. In tutti i casi eccetto uno sono state ravvisate alterazioni tomodensitometriche compatibili con la diagnosi di atrofia cerebellare. Specifici pattern di alterazioni sono stati riscontrati nell'atrofia olivo-ponto-cerebellare e nell'atrofia cerebellare degli alcolisti cronici. I rilievi tomodensitometrici nei soggetti con degenerazione spinocerebellare non sono stati omogenei, variando da un quadro di atrofia cerebellare diffusa di marcata entità ad un quadro di normalità, e sono apparsi in probabile correlazione con l'età dei pazienti e la durata della sintomatologia.
    Notes: Abstract Computerized tomography was performed in 31 patients presenting clinical signs of cerebellar degeneration. CT abnormalities consistent with cerebellar atrophy were found in all cases but one. Specific patterns of abnormality were found in olivo-ponto-cerebellar degeneration and in alcoholic atrophy. The CT findings in spino-cerebellar degeneration were varied, ranging from severe diffuse cerebellar atrophy to normality, possibly according to age and duration of symptoms.
