The distribution pattern of disseminated small lung nodules was radiologically stud- ied with special reference to the relationship between lesions and the bronchial branching system using inflated and fixed lungs of 6 cases Obtained from autopsy. The bronchogenous spread lesions, which were seen in endobronchial tuberculosis and bronchopneumonia, were located in the centriacinar portion of the secondary lobule. Their distribution patterns were regular and corresponded to the bronchial branching pattern. On the other hand, the hematogenous spread lesions, which were seen in miliary tuberculosis and pulmonary metastasis of carcinoma, had no relation to airway structures. They were randomly distributed regardless of bronchial branching. Recognition of these different distribution patterns is important for evaluating diffuse lung diseases by computed tomography.
