Pulmonary Aspergillosis의 방사선학적 고찰 = A Radioclinical Observation of Pulmonary Aspergillosis

다국어 초록 (Multilingual Abstract)

Pulmonary aspergillosis can be hardly recognized as such roentgenologically; the smooth dense lesions, often with cavities, are indistinguishable from Tuberculosis and other disease. Since tuberculosis is a common pulmonary disease in this country. Aspergillosis is easily misdiagnosed as tuberculosis and a acute form of aspergillosis is misinterpretated as pneumonia, because of their similartities in roentgenographic findings. Dense spherical masses of fungus growth, called mycetomas or Aspergillomas and better known as fungus balls, are sometimes found in association with destructive pulmonary disease, including carcinomar and bronchiectasis. Such a mass can be confused with tumor but may be indentified if it is lying in a cavity and mantle of air is seen between the mass and the cavity wall. Tomograms will sometimes show a characteristic air cap. In sputum culture there lies a troublesome problem because of a ubiquity of Aspergillus. And there is no reliable skin test or ser logic test Aspergillosis. The 18 cases of Aspergillosis, proven by surgery, histopathology or/with sputum culture under a strict procedure, were encountered at National Medical Center in the long period of time from April 1962 to November 1976, and those cases are analyzed radiologically and clinically. The following results were obtained: 1. The 10 cases of pulmonary aspergillosis were found in male and the 8 cases in female. Their age range was wide from 20 to 60 years. And the 12 cases (67%) were in the age of 20 to 40 years. 2. The most frequent site of the lesion was in the right upper lobe (9cases). 3. There were 12 (67%) cases of primary aspergillosis and 6 cases of 2ndary one. 4. The characteristic fungus ball with the air cap within the cavity was demonstrated in 8 cases n the tomographic study. 5. The main clinical symptoms were composed of chronic coughing, purulent sputum and hemoptysis and the 10 cases of these patients were misdiagnosed to have tuberculosis. And the 5 c ses had antituberculosis therapy for more than 5 years. 6. The pulmonary tuberculosis and pleurisy were the most frequent associated disease in pulmonary Aspergilosis.
