Abstract:
Objective To research the imaging classification and dynamic changing of bronchioloalveolar carcinoma (BAC). Methods The imaging types of BAC proved by operation and pathology in 32 cases were divided into single nodules, single segment or lobe consolidation, multiple segments or lobar consolidation and multiple diffuse nodules according to the features of plain chest films and CT at first examination. The spreading lesions in lung were recorded.The developing course and changes in size of lesions on the followed-up plain films and CT were observed, then the developing rules of different types of BAC were analyzed. Results The single noduli were enlarged and became poor defined opague shadows gradually. The single segment or lobar consolidation enlarged until the whole lobe. All single lesions progressed and coexisted with diffused nodular or opaque pulmonary involvement eventually. Multiple segments or lobar consolidation developed from peripheral to center of the segment or lobar, diffused pneumonia-like shadows appeared simultaneous. Multiple extensive nodules showed a trend of getting larger and then fused.Conclusion Different types of BAC have theirown developing rule,but they finally form a consequence that the primary lesion coexisted with the spread ones from different way.
