Allergic bronchopulmonary aspergillosis (ABPA) is a pulmonary disorder characterized by hypersensitivity reaction to Aspergillus, mainly Aspergillus fumigatus with variable radiological findings. The prevalence of ABPA is about 1-2% in patients with asthma and 5-15% in patients with cystic fibrosis. Very infrequently the disease is diagnosed in patients without previous bronchial asthma. The case of 45 year old women has been shown, who was admitted to the hospital with suspicious of lung cancer with hilar lymphadenopathy, without asthma. After examinations ABPA has been diagnosed. After treatment clinical, radiological, serological improvement were observed.
