A 56-year-old woman was referred to our hospital for recurrent asthma of 20 years duration. She was diagnosed as having allergic bronchopulmonary aspergillosis on the basis of clinical symptoms, peripheral blood eosinophilia, elevated total serum immunoglobulin E value, positive results of specific IgE and precipitating antibodies against Aspergillus sp., central bronchiectasis, and mucoid impaction. Systemic corticosteroids and anti-fungal therapy improved her symptoms, but the cessation of these treatments led to frequent exacerbations. Omalizumab improved her asthmatic symptoms to the point that corticosteroids could be stopped; however, radiological findings were not improved, and coexisting eosinophilic sinusitis and otitis media worsened. After her treatment was changed from omalizumab to mepolizumab, not only her asthmatic symptoms but also her sinusitis and otitis media became well controlled, and chest radiological findings improved.
