A pulmonary cavitated mass complicating long-standing allergic bronchopulmonary aspergillosis

BCG is a rare disorder, mostly seen, in asthmatic patients, with bronchopulmonary aspergillosis. The clinical features and non-invasive investigations in this disease are not pathognomonic and do not allow to make a confident diagnosis, which can only be confirmed on a pathological basis. In this case, patient had never suffered from asthma. Moreover, the presentation of BCG as an excavated mass is very uncommon. The surgical procedure was considered as therapeutic. Otherwise, the response of BCG to steroids is excellent and its prognosis better than that of angiocentric granulomatosis.
