  • Image 3. Pigmentation of Aspergillus versicolor colonies ranged from pale green to greenish-beige, pink-green, dark green and brown. Reverse is usually reddish. The growth rate is usually slow. Cultured on Sabouraud dextrose agar with chloramphenicol.

  • 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
