    Notizen: Abstract A case of a right cervical aortic arch associated with a subaortic left brachiocephalic vein is reported. CT and MRI findings were correlated to the angiogram. The mechanism responsible for the coexistence of these two abnormalities is discussed.

    Notizen: Abstract The purpose of the study was to evaluate the CT abnormalities of airways and lung parenchyma in asthmatic patients and to assess inter- and intraobserver variability for these abnormalities. The CT scans of 50 asthmatic patients and 10 healthy volunteers were assessed independently by four independent chest radiologist who were masked with respect to the clinical information. Bronchiectasis involving mostly subsegmental and distal bronchi was noted in 28.5% of the asthmatic subjects and none of the non-asthmatics. Bronchial wall thickening, small centrilobular opacities and decreased lung attenuation were observed in 82%, 21% and 31% of asthmatic patients respectively, compared with 7%, 5% and 7% of healthy subjects. The intra- and inter-observer agreements for these four CT abnormalities were measured by the kappa statistic and ranged from 0.60 to 0.79 and from 0.40 to 0.60, respectively. It os concluded that asthmatic patients may exhibit bronchial wall thickening, bronchiectasis and morphological abnormalities suggestive of distal airways disease that can be assessed on CT scans with a clinically acceptable observer variability.

    Notizen: Abstract Posttransplant lymphoproliferative disorders (PTLD), developing after immunosuppressive therapy in human organ-graft recipients, are, for the most part, Epstein-Barr virus-induced. The earlier the diagnosis is made, the greater the potential for reversibility. The chest radiographs and CT scans of 10 patients with thoracic locations of PTLD were reviewed. Mediastinal (n = 3) and hilar adenopathy (n = 2), pulmonary nodules (n = 8), and pleural thickening or effusion (n = 4) were encountered. The incidence of partial resolution with clinical remission (n = 4) appears to be noteworthy, and in all likelihood is related to the extensive necrosis (n = 5) that is frequently seen. Slow regression, transitory deterioration in one case, and localization only on the graft side in two cases, were observed. These morphological and evolutionary peculiarities must be known in order to optimize the diagnosis, and thus the prognosis, of these very original disorders.
