Allergic bronchopulmonary aspergillosis with cavitary lesion simulating a lung abscess.

A 48-year-old female patient was diagnosed as a case of allergic bronchopulmonary aspergillosis (ABPA) on the basis of clinical, immunological and radiological criteria. In addition to central bronchiectasis, computed tomography (CT) of the thorax revealed hilar lymphadenopathy and cavitary lesions simulating a lung abscess, a presentation not described earlier. The patient responded to treatment with corticosteroids and the CT repeated after 14 months of treatment showed complete resolution of the cavitary lesions.
