肺既存構造を進展する疾患の画像診断

We reported one case each of pulmonary tuberculosis, allergic bronchopulmonary aspergillosis and intimal sarcoma of the pulmonary artery. In pulmonary tuberculosis and allergic bronchopulmonary aspergillosis, we recognized gloved finger like shadows. In the former, the shadoes extended to the adjacent bronchoarterial sheath and alveolar spaces, and in the latter, it extended to the ectatic bronchial lumen. In the intimal sarcoma, the lesions resembled multiple nodular shadows; however, the pulmonary artery markedly increased in diameter and elongated. We emphasized the relation of the lesions to inherent structures of the lung instead of pattern recognition in order to interpret chest radiogramas.
