Abstract
A case of allergic bronchopulmonary aspergillosis, 19-year-old male, is presented. He had atopic type asthma in his past history. The chest X-ray film revealed nodular and macular shadows in the right middle field. Eosinophil counts in peripheral blood were 833/mm3. The diagnosis was established by a prick test with an aspergillus extract, its gave an immediate reaction and a late reaction developed after two and half hours. By corticosteroid treatment the shadows disappeared within several days. The bronchogram conducted after the treatment, showed the characteristic pattern of bronchiectasis (saccular type) associated with allergic aspergillosis.
