摘要(Abstract):

目的探讨炎性肌纤维母细胞瘤的计算机断层摄影(computed tomography,CT)表现,以提高对该病CT表现的认识。方法选择本院9例经病理证实的炎性肌纤维母细胞瘤患者,回顾性分析其CT平扫及增强表现。结果 CT示肺内肌纤维母细胞瘤3例,2例表现为界限清楚的肿块,1例仅表现为支气管阻塞,未见肿块;纵隔肌纤维母细胞瘤3例,CT均表现为软组织密度肿块,1例界限清楚,2例与周围结构分界不清;鼻根部、颈部及盆腔肌纤维母细胞瘤各1例,表现为囊实性或实性肿块,部分病变界限不清,侵犯周围组织;3例病变增强扫描后呈明显不均匀强化。结论炎性肌纤维母细胞瘤CT表现具有一定的特点,但最终确诊仍需依靠病理学。
Objective To summarize the computed tomography (CT) features of inflammatory myofibroblastic tumor(IMT). Methods CT findings were retrospectively reviewed in 9 patients with pathologically proved IMT. Results Three IMTs in the lungs were detected by CT . Two of them manifested masses with well demarcation while another case only showed bronchial obstruction without detectable mass. Three tumors were located in the mediastinum and showed soft tissue attenuation under CT. One was well-defined and the other two had unclear border with the surrounding structures. IMTs were also found at nasion (n=1), neck (n=1), and pelvis (n=1), which were shown to be cystic-solid or solid masses while some tumors were invasive with ill-defined margin. After contrast administration, 3 cases showed marked heterogeneous enhancement. Conclusion IMTs have certain CT features, but the final confirmation depends on pathology.
