Allergic bronchopulmonary aspergillosis simulating as lung mass

Abstract

Allergic bronchopulmonary aspergillosis (ABPA) is a commonly diagnosed entity in patients with a long standing history of asthma. Patients with ABPA can have diverse radiological manifestations. Very rare cases of ABPA, presenting as lung mass have been reported. We hereby report a case of ABPA in whom a large symptomatic lung mass was the presenting manifestation leading to consideration of lung cancer as a differential diagnosis. The establishment of ABPA as the underlying cause lead to conservative medical treatment, which was followed by complete resolution of the mass like opacity.
