CT features of 42 cases with pathologically proven bronchioloalveolar carcinoma were retrospectively analysed for pattern, size, location and secondary signs suggesting the diagnosis. Bronchioloalveolar carcinoma had one of the following patterns: solitary nodule or mass (16), lobar consolidation (10), multilobar consolidations (13) and diffuse nodules (3). The 16 solitary nodules or masses ranged in size from 2.0 to 9.4 cm (mean +/- SD 3.75 +/- 1.7 cm). Eleven of the 16 nodules or masses were peripheral and five were central: Eight of the 16 tumours had pleural tags, seven had spiculated margins, and three had bubblelike lucencies. The consolidations were peripherally distributed in 13 out of 23 cases; cystic airspaces were observed in 19 out of 23 consolidations; bulging of interlobar fissures in 8 out of 23; and the angiogram sign in 7 out of 23. In conclusion, computed tomography findings of bronchioloalveolar carcinoma have a wide spectrum, showing typically a peripheral nodule or consolidation. Computed tomography has a role in the diagnosis of nodular localized versus other forms, with subsequent therapeutic and prognostic implications. ER -
