Abstract
A report was made on a case of moist pleurisy suspicious of tumor on X-ray picture comparisons being made with similar cases experienced in the past which were 2 cases of the cancer of the lung, 1 cases each of the pulmonary suppuration and pulmonary fibroma.
Separately, discussions were made on the differential diagnosis of the cases showed round shadows on thoracic X-ray picture, namely, 1 case each of the localized tuberculous piothorax, cancer of the lung, pleural fibroma and 2 cases of the intrapleural tuberculous absess, and on the necessity of the use of X-ray pictures, especially, by tomography.
In order to avoid mistaken diagnosis, moreover, by the gradiated shadow, the importance of taking the nucleated shadow was emphasized for ascertaining the locality and the shape of the lesion.
