An asthmatic woman, aged 53 years, presented with recurrent respiratory tract infections over several years. These episodes were characterized by productive cough with expectoration of thick, yellowish sputum. There was no history of hemoptysis. She received multiple courses of antibiotics for these infections, with only partial response. There was no history of tuberculosis exposure or travel to endemic areas. There had been no major weight loss, and examination showed her chest to be normal. Routine laboratory workup revealed an eosinophil count of 1.6 x 10~9/L(N<0.5 x 10~9/L)andimmunoglobulin E(IgE) levels of 1229 mug/L (N < 240). A bronchoalveolar lavage was performed, and results were negative for fungal and mycobacterial cultures. The chest X-ray (Figure 1) and computed tomography (CT) scan images (Figures 2, 3 and 4) are provided.
