摘要：

PURPOSE: To assess an early thin-section computed tomographic (CT) finding of the localized formation of bronchioloalveolar carcinoma (BAC). MATERIALS AND METHODS: From October 1994 to September 1995, four consecutive patients with biopsyproved BAC were studied. Thin-section CT (n = 4), radiographic (n = 4), pathologic (n = 4), and positron emission tomographic (n = 2) findings were analyzed. RESULTS: Chest radiographs showed focal areas of poorly defined nodules (n = 2) and poorly defined opacity (n = 2). At thin-section CT, lesions appeared as isolated areas of ground-glass attenuation (n = 2) and mixed areas of ground-glass attenuation and consolidation (n = 2). The areas of ground-glass attenuation were 1.8-11 cm in longest diameter. A focal, isolated area of ground-glass attenuation changed into mixed areas with consolidation at serial CT in one patient. Mucinous and nonmucinous BACs were observed in two patients each. Positron emission tomography showed false-negative results for malignancy. CONCLUSION: Focal areas of ground-glass attenuation at CT could be an early sign of localized BAC.
