XXXX : prognostic implication of high-resolution computed tomography features.

@entity1 @entity231 @entity3794 @entity3616 @entity854
PURPOSE: Most @entity1 with biopsy-proven @entity3616 ( @entity3616 ) show complete resolution of radiographic lesions with treatment, but some @entity1 do not respond to treatment and progress to @entity3794 . The authors investigated the prognostic implication of high-resolution computed tomography (CT) features in this condition. METHOD: We reviewed the high-resolution CT findings of 26 @entity1 diagnosed with @entity3616 by histopathology, who had radiographic follow-up for a median of 44 weeks after treatment. We scored the presence and extent of each pretreatment high-resolution CT finding (ground-glass opacity, consolidation, nodules, @entity231 , and honeycombing). The predominant pattern and distribution of the lesions were recorded. Follow-up radiographs were used to determine whether the parenchymal abnormalities had regressed or progressed in response to treatment. RESULTS: Of the 26 @entity1 , 9 had persistent or progressive parenchymal abnormalities at follow-up (group 1), whereas 17 had complete or partial @entity854 (group 2). Consolidation was present on the initial CT scan in 14 (82%) of the 17 @entity1 in group 2, but in only 2 of the 9 @entity1 in group 1 (P = 0.009). None of the 6 @entity1 who had @entity854 as the predominant pattern on initial CT showed complete resolution on follow-up imaging (P = 0.02). CONCLUSION: In @entity1 with @entity3616 , the CT finding of consolidation is associated with partial or complete resolution, whereas @entity231 is associated with persistent or progressive disease.
