    Notes: Abstract A case of Turcot's syndrome is described in an 8-year-old girl. Turcot's syndrome is a rare hereditary disease in which malignant glioma of the central nervous system is associated with colonic polyposis. The patient initially presented with a left parietal glioblastoma diagnosed by computed tomography (CT), and was subsequently found to have nonfamilial colonic polyposis.

    Notes: Abstract. We describe a rare case of hemoperitoneum due to spontaneous rupture of a giant cavernous hemangioma of the liver. CT demonstrated both the intraperitoneal hemorrhage and the hepatic lesion, which showed an atypical multicystic appearance. Furthermore, CT showed the site of rupture of the hemangioma.

    Transudative vs exudative pleural effusions: differentiation using Gd-DTPA-enhanced MRI (1997)
    Springer
    European radiology 7 (1997), S. 860-864 
    Details
    ISSN: 1432-1084
    Keywords: Key words: Pleura ; Effusion ; Exudates ; Transudates ; MRI ; Gd-DTPA
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract. The aim of this study was to investigate the capability of Gd-DTPA-enhanced MRI to differentiate between exudative and transudative pleural effusions. An MRI examination was performed on 22 patients with different types of pleural effusion (10 transudative and 12 exudative effusions). T1-weighted SE images were obtained before and 20 min after administration of Gd-DTPA (0.1 mmol/kg). The degree of enhancement of pleural effusions was evaluated both by visual assessement and by quantitative analysis of images. None of 10 transudative effusions showed significative enhancement, whereas 10 of 12 exudative effusions showed enhancement (sensitivity 83 %, specificity 100 %, positive predictive value 100 %). The postcontrast signal intensity ratios (SIRs) of exudates were significantly higher than corresponding precontrast ratios (P = 0.0109) and the postcontrast SIRs of exudates were significantly higher than those of transudates (P = 0.0300). Exudative pleural effusions show a significant enhancement following administration of Gd-DTPA. We presume that this may be caused by increased pleural permeability and more rapid passage of a large amount of Gd-DTPA from the blood into the pleural fluid in case of exudative effusions. In our limited group of patients, signal enhancement proved the presence of an exudative effusion. Absence of signal enhancement suggests a transudate, but does not exclude an exudate.

    Notes: Abstract. Bronchioloalveolar carcinoma (BAC) is a polymorphic lung cancer the incidence of which is rising. The presence of intratumoral radiolucencies is an important feature of bronchioloalveolar carcinoma.The aim of this study was to present pictorially the spectrum of intratumoral radiolucencies visible in BAC. In 57 BACs studied with thin-slice CT, we identified six types of radiolucencies: (a) patent intratumoral bronchioles (air bronchiologram); (b) pseudocavitations; (c) cavitation; (d) serpentine radiolucencies; (e) internal alveologram; and (f) multiple cystic lesions.

    CT and MR findings in neoplastic perineural spread along the vidian nerve (2000)
    Springer
    European radiology 10 (2000), S. 521-526 
    Details
    ISSN: 1432-1084
    Keywords: Key words: Nerve – Cranial neoplasms – Pterygoid canal – CT – MR imaging

    Topics: Medicine
    Notes: Abstract. The aims of this article are to describe the findings of perividian tumor spread and to compare the accuracy of MRI and CT in diagnosing perineural metastasis along the vidian nerve. Moreover, the frequency of perividian metastasis in patients with head and neck cancer was evaluated. The CT and MR examinations of 98 consecutive untreated patients with histologically proven head and neck cancer were retrospectively reviewed. We considered as criteria for perineural tumor spread along the vidian nerve the following CT and MR findings: For CT (a) enlargement of the pterygoid canal, (b) erosion of its bony wall, and (c) obliteration of its normal fatty content; and for MR (a) enlargement of the vidian nerve, (b) enhancement of the nerve, and (c) obliteration of fat, particularly in the anterior part of the pterygoid canal. Ten patients met the selected criteria for perineural metastasis, which was bilateral in 3 patients, with a total of 13 vidian metastases. The CT scans demonstrated unilateral involvement of the vidian nerve in 9 patients. The MRI scans showed 13 perineural metastases. In 3 patients MR scans demonstrated involvement of four vidian nerves that appeared normal on CT examinations. The diagnostic difference between CT and MRI was statistically significant (Fisher's exact test; p = 0.04). Perineural spread along the vidian nerve is an event more frequent than previously reported and must be investigated with a careful imaging technique. Although a major limitation of our study is the lack of histological proof, the MR finding of a significant enhancement of the nerve, whether enlarged or normal in size, could be considered very suggestive of this kind of metastatic spreading, particularly if associated with simultaneous involvement of the neighboring structures (pterygopalatine fossa, foramen lacerum, trigeminal branches, etc.).

    Notes: Abstract. Hepatic angiomyolipoma (AML) is a rare tumor containing a variable amount of fat. Angiomyolipoma prevalently constituted by vessels can be difficult to differentiate from other hypervascular hepatic tumors containing a small amount of fat. We describe US power Doppler findings in a case of hepatic AML with minimal fat content.

    Description / Table of Contents: Résumé L'objectif de l'étude présentée est d'établir un modèle géologique-géotechnique du remplissage de la plaine alluviale du Tibre dans la région de Rome. L'approche est multidisciplinaire. Les sédiments de remplissage ont été finement analysés sur une coupe basée soit sur les observations de carottes de 57 sondages, ou sur des essais de laboratoire sur divers types d'échantillons. Des données relatives à la géologique, la géomorphologie, le climat, le réseua hydrographique, le développement urbain et l'histoire de la région de Rome ont été utilisées pour interpréter cette coupe et pour extrapoler les données au centre historique de Rome, dans le but d'établir un modèle. Le modèle proposé est un modéle global prédictif, différent d'un modèle détaillé, qui peut être utilisé comme un point de départ pour des projets qui seront développés dans le corps alluvial de la plaine du Tibre, ou pour définir une approche spécifique de problèmes techniques en rapport avec ces projets.
    Notes: Abstract  The study develops a geological/geotechnical model of the filling of the buried Tiber River valley in the area of Rome. The approach has been multidisciplinary: the fill sediments have been analysed in detail and are given on a cross section based on either the observations of 57 borehole cores and/or the laboratory tests on various types of samples. Information regarding the geology, geomorphology, climate, hydrographic network, urban development and history of the Rome area has been used to interpret this section and to extrapolate the data to the historical centre of Rome in order to formulate the model. The proposed model is a global forecasting rather than a detailed one and can be used as a starting point for projects to be conducted in the Tiber River alluvium or for defining a specific approach to technical problems linked to these projects.
