[Radiation diagnosis of bronchioloalveolar cancer]. / Luchevaia diagnostika bronkhioloal'veoliarnogo raka.

The paper analyzes the results of examination of 260 patients with bronchioloalveolar cancer (BAC) who were followed up at the Russian Research Center of Radiology and Roentgenology for 30 years. It provides its clinical, X-ray, and morphological manifestations and classification and the methodological aspects of differential diagnosis. An optimum radiation diagnosis programme has been drawn up, which involves currently available procedures, including computed tomography. The morphological forms of BAC are given in detail.

[Clinico-roentgenologic diagnosis of disseminated and diffuse lung diseases]. / Kliniko-rentgenologicheskaia diagnostika disseminirovannykh i diffuznykh porazhenii legkikh.

The results of clinical and x-ray investigations of 398 patients with disseminated pulmonary lesions were analyzed. Two groups were identified: patients with interstitial type of lesions (101) and patients with focal type of lesions (297). Proceeding from roentgeno-morphological correlations, the authors presented specified roentgeno-semiotics of 10 nosological entities with the syndrome of pulmonary dissemination. The possibilities of optimization of differential diagnosis of disseminated pulmonary lesions were shown basing on combined (clinical, functional and roentgenological) investigation.

[Bronchoalveolar cancer (clinical, x-ray and morphologic characterization)]. / Bronkhioal'veoliarnyi rak (kliniko-rentgenomorfologicheskaia kharakteristika).

The authors presented a clinicoroentgenological picture of bronchioloalveolar cancer based on the analysis of 154 cases; 4 types of disease were defined: peripheral tumors, pseudopneumonic type tumors, multiple nodular formations, and mixed type tumors. Common features of this disease and symptomatology of each separate type were described. The most prominent features of bronchioloalveolar cancer are the absence of bronchial tree involvement and frequent presence of typical cavities with well defined outlines and "lattice" structure. The characteristic features of peripheral bronchioloalveolar cancer are slow growth rates, subpleural localization, inhomogeneous structure, and irregular outlines. The mixed type (far advanced tumors) is characterized by the combination of lobular, spheroidal and microfocal changes. Early recognition of definite types of bronchioloalveolar cancer ensures timely surgical treatment and prevents disease progression to disseminated bilateral lesions.

[Phlebography of the mediastinum in lung cancer]. / Flebografiia sredosteniia pri rake legkogo.

The state of the major mediastinal veins was studied in 113 patients with central cancer of the right lung upper lobe with metastases to the regional lymph nodes. Routine angiography was performed in 92 patients, digital subtraction angiography--in 21 patients. Vascularization was shown to be more common in and adenocarcinoma. The authors identified 2 groups of angiographic signs: marked and doubtful ones. They have been of opinion that only the presence of marked signs can be a contraindication for surgical intervention. The informative value of routine angiography was compared with that of digital subtraction angiography.
