A woman aged 80 years was admitted to hospital with dyspnea, cough, and fatigue, which she had had for 2 years. She reported having pulmonary tuberculosis when she was aged 15 years. The patient had no smoking history. She was using bronchodilator drugs for asthma and levothyroxine for hypothyroidism. In the physical examination, decreased breath sounds on the right side and mild wheeze were found. Her complete blood count and biochemistry parameters were normal. Lung function tests revealed a mild obstructive pattern: forced vital capacity (FVC) 1.60 L (92.7% predicted), forced vital capacity in one second (FEV1) 1.22 L (88.7% predicted), and the FEV1/FVC ratio was 0.76.
