The Spectrum of Radiologic Findings in Allergic Bronchopulmonary Aspergillosis

Abstract

Early diagnosis of allergic bronchopulmonary aspergillosis (ABPA) is important. Initiation of corticosteroid therapy in ABPA is essential to prevent progressive destruction of lung parenchyma. The earliest radiographic manifestations of the disease may be present only on bronchograms. In addition to the classic radiographic findings (infiltrate, massive homogeneous consolidation, tram-line shadow, parallel line shadow, ring shadow, toothpaste shadow, glove-finger shadow), perihilar infiltrates simulating adenopathy (pseudohilar adenopathy) and air fluid levels were frequently demonstrated.
