Any case of unresolving chronic pneumonia with expectoration of thick mucoid plugs should have high index of suspicion for plastic/cast bronchitis, requiring early flexible bronchoscopy with lavage and histopathologic evaluation. Associated presence of idiopathic chronic eosinophilic pneumonia is unusual and could be considered as a cause for atypical plastic bronchitis complicated by bronchiectasis.
