@entity3977 in XXXX : usefulness of CT in distinguishing among potential causes.

PURPOSE: To determine whether the computed tomographic (CT) appearances of @entity3977 in @entity1 with @entity791 ( @entity791 ) can help differentiate the potential infectious and neoplastic causes. MATERIALS AND METHODS: The thoracic CT scans obtained in 60 @entity1 with @entity791 and @entity3977 were reviewed retrospectively by two thoracic radiologists who were blinded to clinical and pathologic data. The scans were evaluated for nodule size, distribution, and morphologic characteristics. CT findings were correlated with final diagnoses. RESULTS: Thirty-six (84%) of 43 @entity1 with @entity1292 had a predominance of nodules smaller than 1 cm in diameter, whereas 14 (82%) of 17 @entity1 with a @entity5 had a predominance of nodules larger than 1 cm (P <.001). Of the 43 @entity1 with @entity1292 , 28 (65%) had a centrilobular distribution of nodules; only one (6%) of 17 @entity1 with a @entity5 had this distribution (P <.001). Seven (88%) of eight @entity1 with a peribronchovascular distribution had @entity2826 (P <.001). CONCLUSION: In @entity1 with @entity791 who have @entity3977 at CT, nodule size and distribution are useful in the differentiation of potential causes. Nodules smaller than 1 cm, especially those with a centrilobular distribution, are typically infectious. Nodules larger than 1 cm are often neoplastic. A peribronchovascular distribution is suggestive of @entity2826 .
