    Beschreibung / Inhaltsverzeichnis: Zusammenfassung. Wir berichten über unsere Erfahrungen an 3 Patientinnen mit einem solid-pseudopapillären Tumor des Pankreas. Charakteristisch für diesen semimalignen Tumor sind das Vorkommen bei jungen Frauen, die auffallende Größe (bis 10 cm) und das seltene Auftreten von Metastasen. Trotz erheblicher Größe der Tumoren war in allen Fällen eine kurative Resektion möglich. Präoperatives Hauptunterscheidungsmerkmal zum duktalen Adenocarcinom war in allen Fällen die normale Weite des Pankreasgangs ohne Gangabbruch. Im Gegensatz zu den meisten anderen Tumoren des Pankreas hat dieser Tumor eine gute Prognose. Alle unsere Patientinnen sind z. Z. (bis zu 8 Jahren nach der Operation) rezidivfrei.

    Notizen: Summary. We report on three female patients with solid pseudopapillary tumors of the pancreas. The histogenetic origin of this entity is still unclear. The tumor, usually occurring in young women, forms large masses (up to 10 cm in diameter) before becoming symptomatic. Metastases have very rarely been reported. In contrast to other pancreatic tumors, the main pancreatic duct was displaced, but of normal caliber without stenosis, in all our patients. Despite the large size of the tumors, they were curatively resected in all three cases. Two of the tumors infiltrated the parenchyma or adipose tissue of the pancreas but did not spread into the lymph nodes or other organs. All of the patients are alive and without signs of tumor recurrence up to 8 years after surgical resection.

    Notizen: Abstract  A-52-year-old patient presented with a 2-year history of multiple myeloma, recurrent episodes of hypercalcemia, and extensive bone involvement. She developed pulmonary infiltrates, initially misdiagnosed as interstitial pneumonia. High-resolution computed tomography and bone scintiscanning indicated pulmonary calcification, which was confirmed by a transbronchial biopsy. Cytostatic treatment of multiple myeloma in combination with repetitive i.v. administration of bisphosphonates over a period of 6 months led to a significant improvement of clinical symptoms. Regression of pulmonary infiltrates was demonstrated by chest radiograph and computed tomography. There are only a few reports on pulmonary calcification in patients with multiple myeloma; the condition was associated mostly with progressive disease, kidney failure, adult respiratory distress syndrome and bad prognosis. In our patient isolated calcification of the lungs without involvement of other organ systems was successfully treated. These findings suggest that interstitial pulmonary calcinosis in multiple myeloma can be reversed by normalization of serum calcium levels using bisphosphonates combined with cytostatic treatment.

    Beschreibung / Inhaltsverzeichnis: Summary Objective: Determination of the proportion of the dose-area product caused by fluoroscopy at voiding cystourethrography in children, using digital image intensifier technology. Patients and methods: Using computer-assisted dosimetry, we determined the dose-area product and the respective proportions of the dose-area product caused by fluoroscopy and radiography as well as the number of radiographs taken at a given examination of 40 children (8 children less than 2 years old, 15 children between 2 and 6 years old and 17 children between 6 and 15 years old). Results: The computer software program correctly differentiated between fluoroscopy and radiography in 80 % of cases. Incorrect results were primarily observed in newborns and young children. The total radiation dose ranged in relation to patient age from 22 to 651 cGy × cm2. Fluoroscopy was responsible for an average 78 % of the applied radiation dose. Conclusion: Computer-assisted dosimetry is useful in determining the proportion of the dose-area product caused by fluoroscopy in older children undergoing voiding cystourethrography. When image intensifier technology is used, this accounts for more than 75 % of the total radiation dose. The method is not suitable for use in small children.
    Notizen: Zusammenfassung Ziel: Bestimmung des Anteils der Durchleuchtung am Gesamtflächendosisprodukt beim Kindermiktionszysturethrogramm in digitaler Bildverstärkertechnik. Material und Methode: Bei 40 Kindern (8 Kinder 〈 2 Jahre, 15 Kinder zwischen 2 und 6 Jahren und 17 Kinder zwischen 6 und 15 Jahren) wurden PC-gestützt die Anzahl der Zielaufnahmen, deren Anteil am Gesamtflächendosisprodukt sowie der durchleuchtungsbedingte Anteil am Gesamtflächendosisprodukt ermittelt. Ergebnisse: In 80 % der Fälle ermöglichte der Einsatz des Computerprogramms eine korrekte Differenzierung zwischen Fluoroskopie und Radiographie. Falsche Ergebnisse fanden sich hauptsächlich bei Neugeborenen und Kleinkindern. Die Gesamtstrahlenbelastung variierte abhängig vom Patientenalter zwischen 22 und 651 cGy × cm2, durchschnittlich betrug der Anteil der Durchleuchtung 78 %. Schlußfolgerung: PC-gestützt ist es möglich den Anteil der Durchleuchtung am Gesamtflächendosisprodukt bei älteren Kindern, die sich einem Miktionszysturethrogramm unterziehen, zu ermitteln. Dieser beträgt bei Verwendung der digitalen Bildverstärkertechnik mehr als 75 %. Bei Neugeborenen und Kleinkindern versagt die Methode.

    Notizen: Abstract  Objective. The present study demonstrates the osseous and soft tissue manifestations of alveolar echinococcosis (AE). Patients. We report on eight patients with AE with bone or soft tissue involvement confirmed at biopsy or needle cytology. Results. All eight patients showed hepatic involvement. Four exhibited infiltration of the spine as a result of direct spread of the hepatic primary lesion; distant metastases were observed in only three of these patients. Calcifications, which are typical for hepatic manifestations of the disease, were observed in soft tissue in only two of eight cases (25%); we observed no instances of endovesicular daughter cysts. Conclusion. AE manifests itself in the vertebral column as a form of spondylitis and in soft tissue presents similar to an abscess. Since in most of these cases spread of the disease per continuitatem from the liver is present, the diagnosis is easily made from the characteristic hepatic findings.

    Notizen: Summary. The aim of the trial was to evaluate and compare the safety and efficacy of iopentol (Imagopaque®, Nycomed Imaging AS, Oslo, Norway) and amidotrizoate (Peritrast®, Köhler Pharma, Alsbach, Germany), both 300 mg I/ml initially, but diluted to 2 % (v/v) and administered orally. Sixty-four and 65 patients were included in the respective contrast medium groups. Portions of contrast medium, totally 1.5 l, were taken every 15 min during the hour before the examination. A standard radiological procedure for abdominal CT was followed. Nine percent of the patients in each group experienced adverse events which were possibly contrast medium related. Taste acceptance was comparable in the two groups. Except for the stomach, radiographic efficacy was satisfactory for all intestinal segments. The difference in density in the proximal small bowel (main parameter) achieved with the media was not significant (p = 0.33), nor was that as regards image homogeneity (contrast distribution). In conclusion, iopentol is well suited for oral contrast enhancement of the gastrointestinal tract in abdominal computed tomography.

    Notizen: Abstract. The aim of this study was evaluation of MRI alone and in combination with mammography and galactography in the diagnosis of intraductal papillomas. From 1994 to 1998, a total of 48 women presenting with pathologic mammary secretion underwent galactography and magnetic resonance mammography (MRM). Thirty-five patients aged 16–71 years (average age 46 years) subsequently underwent surgery or diagnostic puncture and the histologic findings were compared with the results of the radiologic examination. Histology revealed papillomas in 16 cases. In 6 of these patients, there was associated malignant degeneration. Malignancy without associated papilloma was observed in 3 cases. Galactography displayed a sensitivity of 94 % and a specificity of 79 % with five false-positive findings and one false-negative finding in the recognition of intraductal papillomas. Malignant processes were detected by mammography/galactography in only one instance. Magnetic resonance mammography visualized pathologic contrast medium uptake in 8 of 9 cases of malignant disease (sensitivity 89 %). One patient with in situ ductal carcinoma escaped detection with MRM. Papillomas showed no or below-the-threshold-lying contrast uptakes with no specific sign suggestive of papilloma. Galactography in combination with mammography remains the primary diagnostic procedure in cases of pathologic mammary secretion or suspected papilloma. The addition of MRI permits exclusion of malignant disease with a high degree of certainty; thus, expectant management in individual cases with negative findings appears justified.
