[Radiologic finding of bronchial asthma].

High-resolution computed tomography (HRCT) scan is a noninvasive technique that might be valuable for evaluating bronchial wall thickening and bronchiectasis as a result of chronic inflammation in patients with severe asthma. HRCT is also useful to diagnose the complications of asthma such as pulmonary emphysema and chronic eosinophilic pneumonia. In addition, HRCT will be able to demonstrate the tracheobronchial and parenchymal abnormality dis- tinctly, with the result that it will be helpful for making differential diagnosis in the patients with wheeze, including allergic bronchopulmonary aspergillosis, eosinophilic granulomatosis with polyangiitis, bronchial tuberculosis and tracheal tumor.
