Possibilities of the computed tomography considered as a part of differential diagnosis of pneumonia and pneumonia-like form bronchioloalveolar pulmonary cancer

Abstract

Authors cover a study performed with the aim to determine differential and diagnostic and, in addition, computer tomographic signs of pneumonia-like form of bronchioloalveolar pulmonary cancer and pneumonia. Data on CT and results of diagnosis and treatment of 36 patients with infiltrates in the peripheral segments of the lungs are analysed. The following features were considered as differential and diagnostic: induration of the type «frosted glass», «CT angiography» symptom, «air bronchogram» symptom, «honeycomb lung», bronchial wall thickening proximal of the affected area, trapped air in the normal lung tissue adjacent to the abnormal areas, pleural thickening and retraction at the level of the lesion.
