Notes:
Confocal scanning laser microscopy (CLSM), using CAAF(green) Fun1(red) stained biofilm. The red color of the FUN 1 cell stain was localized in dense aggregates in the cytoplasm of metabolically active cells. Thus, areas of red fluorescence represented metabolically active cells, and green fluorescence indicated cell wall-like polysaccharides, while yellow areas represented dual staining.

-
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

-
pt.SB – 6/10/98 – bronchocentric granulomatosis. CT scan showing multiple small nodules of variable size in both lung fields, apparently close to the vascular bundles.
-
Bronchial oedema.Remarkably oedematous bronchial mucosa, as seen in ABPA.
-
An example of longstanding allergic bronchopulmonary aspergillosis in a patient who has been steroid dependent for over 15 years showing remarkable kyphoscoliosis and honey combing and fibrosis of both lungs.
-
Recurrent pulmonary shadows 1. 6 Jan 1988 – chest radiograph showing right hilar enlargement, consistent with ABPA.
Recurrent pulmonary shadows 1. 3 Feb 1989 – chest radiograph showing right upper-lobe consolidation and contraction consistent with obstruction of RUL bronchus, in ABPA.
Clearing of pulmonary shadows 3, pt BJ. 5 April 1989 – resolution of shadows seen in February, with a course of corticosteroids.
Recurrence of pulmonary shadows 4, pt BJ. 2 September 1989 – recurrence of pulmonary shadows with an exacerbation of ABPA.
Central bronchiectasis, pt BJ. CT scan of thorax October 1989 showing central bronchiectasis, characteristic of ABPA (and cystic fibrosis).
