This entity is most commonly encountered in patients with longstanding asthmaand only occasionally in patients with cystic fibrosis 4,5. Only rarely does it appear in patients with no other identifiable pulmonary illness 5. Clinically, patients have atopic symptoms especially asthma and present with recurrent chest infection. They may expectorate orange-coloured mucous plugs.

Allergic bronchopulmonary aspergillosis is the result of hypersensitivity towards Aspergillus spp which grows within the lumen of the bronchi, without invasion. The hypersensitivity initially causes bronchospasm and bronchial wall edema, which is IgE-mediated.

Both type I and III allergic reactions have been implicated 4. Bronchocentric granulomatosis often occurs, which is characterised by necrotizing granulomatous inflammation that destroys the walls of small bronchi and bronchioles.

Segmental and subsegmental bronchi are dilated and filled with mucous, admixed with eosinophils and occasional fungal hyphae 4,7. Charcot-Leyden crystals may be prominent 7. Early in aaspergilosis disease chest x-rays will appear normal, or only demonstrate changes of asthma. Transient patchy areas of consolidation may be evident representing eosinophilic pneumonia.

Mucoid impaction in dilated bronchi can appear mass-like or sausage shaped or branching opacities finger in glove sign.

Pulmonary collapse may be seen as a consequence of endobronchial mucoid impaction. Fleeting shadows over time can also be a characteristic feature of this disease These opacities usually appear and disappear in different areas of the lung aspergiosis a period of time as transient pulmonary infiltrates. The main focus of treatment revolves around Many patients are successfully managed after diagnosis and never progress clinically to stage IV or V.

In stages I to III, prognosis is excellent, whereas stage V has a high 5-year mortality from respiratory failure 9. For mucoid impaction consider:. You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Unable to process the form.
