  • Bronchiectasis due to ABPA

    High resolution CT scan images with reconstruction of 1mm thick slices at approximately 10mm increments. The scan shows moderately severe multi-lobar cylindrical and varicose bronchiectasis predominantly centrally and in the upper lungs. There is no mucus plugging seen.

    The features are in keeping with allergic bronchopulmonary aspergillosis
