title: [CT findings of inflammatory myofibroblastic tumor of different pathological types].
abstract: Objective:To explore the computed tomography(CT) features of inflammatory myofibroblastic tumor(IMT) in different pathological types, and improve the diagnostic level of this disease.Methods:The CT features of 29 cases pathologically confirmed IMTs were retrospectively reviewed along with a literature review to analyze the CT features and pathological correlations, and three kinds of pathological classification of IMT in patients with gender , shape, boundary and location were respectively analyzed byChi-Squaretest.Results:The age ranges from 2 to 78 years.There were 7 cases of mucinous blood vessel type and 13 cases of spindle cell type and 9 cases of fiber type.Immunohistochemically, Vimentin (22/29) and SMA (28/29) were positive in all the cases, ALK (4/29) and CD-67(6/29) were partly positive expression, other markers such as S-100 were negative expression.TheChi-Squaretest showed that there were statistically differences in the gender of the patients.Conclusion:The CT and clinical features differ according to pathological types of IMT. Its final diagnosis still needs to be combined with pathology and immunohistochemistry result. In all, CT has a role in assessing the extension of IMT and especially about the relationship with adjacent organs which can effectively direct the establishment of clinical treating scheme.
