Allergic bronchopulmonary aspergillosis presenting as recurrent mass-like consolidation

Abstract

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitive disease showing various radiographic and clinical manifestations. Its clinical course has not been fully understood. Here I describe a case of a 23-year-old immunocompetent man with frequently relapsing ABPA. He was asthmatic. He visited our hospital because of a chronic cough. Laboratory examination showed eosinophilia with increased total and Aspergillus-specific IgE as well as positive skin reaction to Aspergillus fumigatus. Radiologic feature was a dense consolidation. Histology showed organizing pneumonia with eosinophilic infiltration. On the diagnosis of ABPA, he was treated with systemic steroid and itraconazole. Although treatment response was excellent, he suffered from recurrent ABPA three times thereafter in die form of fleeting mass-like consolidation. Copyright
