[Roentgenologic characteristics of bronchopulmonary carcinoma]

The roentgenologic characteristics of bronchopulmonary carcinoma were studied in 578 patients in whom the disease had been diagnosed by bronchoscopy and confirmed by cytopathologic finding. Each of the pulmonary disease may imitate bronchopulmonary carcinoma and vice versa. Since there is no roentgenologic patognomonic sign for bronchopulmonary carcinoma the sorts and distribution of characteristic X-ray signs were examined. In our group of patients in 67% of cases the right side was involved. The leading point in X-ray was in 52.8% of cases the pathologically enlarged hilus unilaterally and bilaterally. In patients with periphery located bronchopulmonary carcinoma the most frequent X-ray sign was unclearly limited shadow in 41.3% of cases. In patients with centrally located bronchopulmonary carcinoma in 6.4% of cases the normal X-ray sign was found. However, in none of 177 patients with periphery bronchopulmonary carcinoma the normal X-ray was found.
