[Prevalent disseminated form of bronchiolo-alveolar cancer].

Three roentgenological variants of the course of the prevalent disseminated form of bronchoalveolar cancer were distinguished proceeding from the clinical and X-ray study: focal-disseminated (5 cases), focal-nodal (11) and focal-infiltrative (16). In the authors' opinion, the prevalent disseminated form of bronchoalveolar cancer is a terminal phase in the development of the more restricted forms of a tumour (nodal and pneumonia-like) which is formed by way of intrapulmonary aerogenic (bronchogenic) metastasis.
