Abstract:
Objective To explore the HRCT characteristics of solitary pure bronchioloalveolar carcinoma.Methods Compared with postop pathological appearance,21 patients with 22 affections tumors which were pathologically confirmed pure bronchioloalveolar carcinoma were retrospectively reviewed.Results the histopathological results prior to surgery showed that 20 patients with 21 affections tumors were non-mucilaginous BAC and 1 patient was mucilaginous BAC.Noguchi's classification:Type A 3 cases,Type B 12 cases,Type C 5 cases.(Mucilaginous BAC was not classified)Stage classification:There were 21 cases with stage ⅠA,the maximum tumor diameter was from 0.3 to 3.0 mm (average diameter 1.3 mm).No case showed pleura metastasis,vessel invasion and lymphaticmetastasis.Appearance of HRCT:according to the amount of GGO,all affections were divided into 4 groups.A group(5/22),B group(7/22),C group(7/22),D group(3/22).There were 11 cases with pleura traction,5 cases with clear boundary and trimmed edges and other 17 cases were contradistinction.There were 21 cases with blood vessel or bronchus shadow.Conclusion HRCT can show scan can provide details of structure characteristics of BAC's pathological histology,so it plays an important role in prediction of pathological infiltration of tumor cells and prognosis assessment.
