Clinical features and x-ray findings of bronchioloalveolar cell carcinoma

The clinical features of bronchioloalveolar cell carcinoma are: slow onset, more than half a year may pass from onset to diagnosis, tumor is located in the peripheral part of the lung, early involvement of the bronchus or pleura, the first symptoms to cough, hemoptysis, progressive dyspnea more common. Imaging findings include uniform and distinct narrowing of the bronchi involved, stiffness and elongation of the bronchi, filling of the bronchi with contrast medium rather than adhesion to the walls, poor filling of the bronchial branches and alveoli, resulting in a withered dendritic bronchial tree, multiple nodular cancer tissue spreading along the lymphatic vessels and presenting as multiple miliary nodules, and pneumonia with consolidation in one or more lobes.
