    Notizen: Abstract The purpose of our study was to determine interobserver variation in the analysis of high-resolution computed tomography (HRCT) in the lungs of patients with clinically suspected bronchiectasis. HRCT scans of 88 patients were analysed independently by three radiologists with variable experience in thoracic radiology using a subjective scoring system to record bronchi as normal, mildly abnormal or severely abnormal. The presence, severity and distribution of bronchial dilatation and bronchial wall thickening were recorded. Kappa values were calculated for assessment of interobserver agreement. Agreement between the three readers was good for the detection of bronchiectasis (kappa 0.78) and assessment of its severity (0.68), detection of bronchial wall thickening (0.64) and moderately good for the assessment of its severity (0.58) on a per-patient basis. When individual lobes were analysed, agreement was moderately good for the detection of abnormal bronchi (0.59). Agreement on the extent of abnormal bronchi using five categories was only fair (0.39), but was good when differences of one category were ignored (0.63). Interobserver variation with HRCT in suspected bronchiectasis appears satisfactory for comparative studies.

    Aspergillus infection of the respiratory tract after lung transplantation: chest radiographic and CT findings (1998)

    Notizen: Abstract. The objective of our study was to assess radiographic and CT findings in lung transplant patients with evidence of Aspergillus colonization or infection of the airways and correlate the findings with clinical, laboratory, bronchoalveolar lavage, biopsy and autopsy findings. The records of 189 patients who had undergone lung transplantation were retrospectively reviewed for evidence of Aspergillus colonization or infection of the airways. Aspergillus was demonstrated by culture or microscopy of sputum or bronchoalveolar lavage fluid or histologically from lung biopsies or postmortem studies in 44 patients (23 %). Notes and radiographs were available for analysis in 30 patients. In 12 of the 30 patients (40 %) chest radiographs remained normal. In 11 of 18 patients with abnormal radiographs pulmonary abnormalities were attributed to invasive pulmonary aspergillosis (IPA) in the absence of other causes for pulmonary abnormalities (8 patients) or because of histological demonstration of IPA (3 patients). In these 11 patients initial radiographic abnormalities were focal areas of patchy consolidation (8 patients), ill-defined pulmonary nodules (2 patients) or a combination of both (1 patient). In some of the lesions cavitation was demonstrated subsequently. At CT a “halo” of decreased density was demonstrated in some of the nodules and lesion morphology and location were shown more precisely. Demonstration of Aspergillus from the respiratory tract after lung transplantation does not necessarily reflect IPA but may represent colonization of the airways or semi-invasive aspergillosis. The findings in patients with IPA did not differ from those described in the literature in other immunocompromised patients, suggesting that surgical disruption of lymphatic drainage and nervous supply or effects of preservation and transport of the transplant lung do not affect the radiographic appearances.

    Linear opacities on HRCT in bronchiolitis obliterans organising pneumonia (1999)

    Notizen: Abstract. The aim of this study was to report the high-resolution computed tomography (HRCT) appearances of linear opacities that may occur in isolation or in combination with other changes in bronchiolitis obliterans organising pneumonia (BOOP). Eleven patients with BOOP and linear opacities on HRCT were identified at three independent teaching hospitals. The HRCT images and clinical course of each patient were reviewed. Two distinct types of linear opacity were identified. The type-1 opacity extended in a radial manner along the line of the bronchi towards the pleura and was usually intimately related to bronchi. The type-2 opacity occurred in a sub-pleural location and bore no relationship to the bronchi. Both types occurred most commonly in the lower lobes, frequently were associated with multi-focal areas of consolidation and usually completely resolved with treatment. There was no associated bronchiectasis, irreversible volume loss or a reticular or honeycomb pattern. In 2 patients linear opacities were the sole abnormality on HRCT. Bronchiolitis obliterans organising pneumonia may occur in a pure “linear form” or HRCT may demonstrate linear opacities in addition to multi-focal consolidation.

    High-resolution computed tomographic appearance of MALToma of the lung (1998)

    Notizen: Abstract. MALToma of the lung is rare and advances in molecular techniques have only recently allowed accurate diagnostic classification of the previously termed “pseudolymphomas” by demonstrating that many are monoclonal B-cell proliferations of MALT tissue and therefore true low-grade lymphomas. No significant previous contribution was found in the literature regarding the high-resolution CT appearance (HRCT) of these tumours. We describe the high-resolution CT appearances in five cases presenting to our institution from 1994 to 1997. The HRCT scans (1-mm sections at 10- to 15-mm intervals) were performed as the opacities seen radiographically were thought to be part of a diffuse lung process. In one patient a spiral sequence was performed through the main airway. Multifocal, ill-defined nodules containing air bronchograms were seen in four cases and focal lobar consolidation in one case. Interlobular septal thickening, centrilobular micronodules and bronchial wall thickening were seen in two cases. Mediastinal lymphadenopathy and pleural reaction do not appear to be characteristic features. The appearance of multifocal consolidation is similar to that seen in bronchoalveolar cell carcinoma and cryptogenic organising pneumonia.
