Serial chest CT findings in XXXX associated with @entity6017 .

@entity1 @entity6017 @entity16 @entity2416 @entity401 @entity6558
OBJECTIVE: A retrospective study was carried out in two institutions to determine serial changes in the pattern, distribution, and extent of @entity401 ( @entity401 ) associated with @entity6558 ( @entity6558 )- @entity6017 ( @entity6017 ) using HRCT. SUBJECTS AND METHODS: Twenty @entity1 with @entity6558 - @entity6017 and clinical suspicion of @entity401 who underwent at least two serial HRCT examinations were retrospectively evaluated by two readers. @entity1 were classified according to the dominant CT pattern which was correlated with clinical evolution and underlying histology when available (n=6). RESULTS: @entity1 were classified into four groups according to the dominant pattern: ground-glass attenuation and reticulation (group 1, n=9); honeycombing (group 2, n=4); airspace consolidation (group 3, n=4), and normal or almost normal lung (group 4, n=3). Under medical treatment, serial HRCT showed that the extent of areas of ground-glass opacities (group 1) decreased in five @entity1 , stabilized in two, and increased in two. Pathologic findings demonstrated @entity2416 ( @entity2416 ) in two cases and unspecified @entity401 in one. In group 2, extent of honeycombing increased in three cases and stabilized in one. In group 3, dramatic resolution of airspace consolidation occurred in three cases. Clinical deterioration with extensive consolidation at CT and @entity16 ( @entity16 ) at histology occurred in one @entity1 of each of the three previous groups. Lesions stayed invisible or progressed slightly in the fourth group. CONCLUSION: In @entity401 associated with @entity6558 - @entity6017 , clinical deterioration and @entity16 in the follow-up can be observed whatever the HRCT pattern. However, unfavorable evolution is constant when honeycombing is present at the initial CT.
