The authors reviewed the computed tomographic (CT) scans and pathologic specimens of 57 histologically proved @entity153 (35 @entity957 , 12 @entity4153 , and 10 @entity420 ) in 47 @entity1 with @entity3794 . The @entity1 ranged in age from 61 to 87 years (mean age, 72 years; 42 @entity1 and 5 @entity1 ). On radiography and CT, most @entity5 (82%) were located in peripheral areas of @entity358 . In 50 of the 57 lesions, the @entity5 were round or lobulated with sharp margins. In seven @entity5 , including six @entity957 and @entity4153 , the @entity5 invaded the @entity358 and lacked distinct margins. Intratumor lucency was seen in 13 @entity5 (five solitary and eight multiple). The CT findings, including high-resolution CT scans, were compared with the histologic findings in a subgroup of 29 lesions in 25 @entity1 with available surgical or autopsy specimens. @entity3 with unclear margins (four lesions), septal thickening of the contiguous/surrounding honeycombed areas (16 lesions), and discrete masses (nine lesions) with solitary (four of nine) or multiple (five of nine) intratumor lucencies. The lucencies in six of nine @entity1 (67%) with intratumor lucencies were found to represent engulfed cystic airspaces histologically. CT revealed that @entity153 associated with @entity3794 has distinct morphologic characteristics that correlate histologically with a specific pattern of @entity5 growth.
