    Notes: Abstract. The aim of this study was to evaluate the clinical relevance of coronary artery calcifications detected by spiral CT, congruence with fluoroscopy (FS) and coronary angiography, and comparison with studies reporting on application of double-helical CT and ultrafast CT. Forty patients underwent spiral CT (2-mm slice thickness, table feed 3 mm/s), coronary angiography, and FS (performed in the usual manner). Stenosis and calcifications were evaluated semiquantitatively. Nineteen patients suffering from a stenosis ≥ 75 % were verified at coronary angiography. All had coronary artery calcification on spiral CT. Fluoroscopy did not detect 8 of 19 patients with a stenosis ≥ 75 % (1 vessel: n = 1; 2 vessels: n = 3; 3 vessels: n = 4). In spiral CT sensitivity was 100 % and specificity was 33 % (FS: 58 and 48 %). Positive predictive value was 83 % for spiral CT (FS: 50 %), and negative predictive value was 100 % (FS: 56 %). A significant linear increase in the calcification score was found for increasing maximal stenosis (p 〈 0.005). Spiral CT is more sensitive than FS in the recognition of hemodynamic relevant stenoses using the detection of coronary artery calcifications. Statistical parameters are comparable to ultrafast-CT. Spiral CT is a suitable non-invasive diagnostic technique in coronary heart disease. Coronary calcifications found incidentally in symptomatic patients at chest CT should be reported to the referring physician for further cardiological workup.

    Notes: Abstract. Renal insufficiency or allergic reactions for X-ray contrast agents are frequent limitations in immunocompromised hosts such as neutropenic or AIDS patients. Due to a better tolerance of contrast agents in MRI, this technique is well suited for investigation of parenchymal organs. We demonstrate an allergic AIDS patient who presented with fever and flank pain. At sonography, anechoic renal lesions were supposed to be non-complicated cysts; however, on T2-weighted MRI, the center was of high signal. Dynamic contrast-enhanced MRI of the kidneys demonstrated an enhancing rim with ill-defined margins. The lesions were supposed to be multiple bilateral abscesses. Due to the multiple dynamic contrast series, a delayed enhancement of renal parenchyma was detectable adjacent to the lesion. This was suggested as accompanying local pyelonephritis and an infectious etiology became more reliable. Aspergillus fumigatus was identified by CT-guided biopsy as the underlying microorganism. The MR appearance of this manifestation has not been described previously.

    Description / Table of Contents: Zusammenfassung. Ein 75 jähriger Patient stellte sich mit seit 2 Jahren langsam größenprogredienten Raumforderungen unterhalb beider Schulterblätter vor. Anamnestisch bestand ein Zustand nach proximaler Oberarmamputation linksseitig mit folgender prothetischer Versorgung. Klinisch zeigten sich direkt unter den Schulterblattspitzen beidseits 2 faustgroße Tumoren, die fest mit dem tiefer gelegenen Gewebe verwachsen waren. Sowohl magnetresonanztomographisch als auch intraoperativ stellte sich ein infiltratives Wachstum dieser Raumforderungen in die seitliche Thoraxmuskulatur und das Periost der Rippen sowie des Schulterblatts dar, so daß ein maligner Tumor vermutet wurde. Histopathologisch zeigte sich Bindegewebe mit zahlreichen eingelagerten fragmentierten und unregelmäßig konfigurierten elastischen Fasern und unscharfer Begrenzung zum umgebenden Fettgewebe, typisch für ein Elastofibrom. Für Malignität bestand kein Anhalt. Im vorliegenden Fall erscheint es wahrscheinlich, daß eine unphysiologische Belastung der oberen Extremitäten bei dem mit einer linksseitigen Oberarmprothese versorgten Patienten die Entstehung der beidseitigen Elastofibrome begünstigt hat. Das Elastofibrom ist ein seltener, gutartiger, fast immer subscapulär gelegener Weichteiltumor, der bevorzugt bei älteren Frauen auftritt. In etwa 10 % der Fälle findet sich ein bilaterales, meist asynchrones Wachstum. Klinisch und radiologisch stellen Lipome sowie Weichteilsarkome die wichtigsten Differentialdiagnosen dar. Andere seltene Elastofibromlokalisationen an Rumpf, Kopf und Extremitäten werden in der vorliegenden Arbeit aufgeführt.
    Notes: Summary. A 75-year-old man had painless, slowly enlarging tumors in the right and left infrascapular regions. Clinically, the tumors were nontender and semimobile. MR imaging and the operative exploration revealed tumors infiltrating the lateral thoracic muscles and periost of the scapula and underlying ribs. At surgery, the tumors were thought to be malignant, most likely liposarcomas. The histological examination showed the characteristic appearance of elastofibromas with spindle-shaped fibroblasts, which were separated by thick eosinophilic collagenous and elastic fibers. Elastofibromas are benign mesenchymal soft-tissue lesions that mainly affect elderly women. In 10 % of the patients bilateral, often asynchronous tumors are seen. Ninety-nine percent of the lesions are located in the subscapular region. Occasional elastofibromas have been described in the extremities, head, and in the abdominal and thoracic cavities.
