炎性肌纤维母细胞瘤CT诊断

The CT diagnoses of inflammatory mofibroblastic tumor

目的探讨炎性肌纤维母细胞瘤影像学特征,提高对本病的认识和诊断。方法收集我院经病理证实的炎性肌纤维母细胞瘤7例,行强化CT检查,结合患者临床病例资料与相关文献报道进行回顾性诊断分析。结果 7例中男性3例,女性4例,中位年龄42岁,病灶均为单发,腹膜后3例,右下腹小肠系膜、左侧髂窝区、右肺及左腹股沟区各1例,临床表现依据肿块发生的部位不同而有不同的表现:腰痛3例,腹痛及腹部肿块2例,咳嗽及下肢肿胀各1例,发热3例,CT平扫均呈实性软组织密度肿块,密度均匀或不均匀,大部分边界较清,增强后均呈不均质强化或明显持续强化,除右肺肿块外,其余6例肿块均不同程度包绕临近动静脉血管,动脉血管管腔通畅,无或略狭窄,血管管壁无破坏,静脉血管多受压移位、狭窄或闭塞,2例伴有局部淋巴结肿大。结论炎性肌纤维母细胞瘤的影像学表现多样,缺乏特异性,确诊仍依赖于病理及免疫组化检查,CT检查能明确肿块的部位、累及的范围、周边浸润的程度、内部结构等,为手术方式的选择提供有效的指导,并对术后复查随访提供重要的参考价值。

Objective To enplore the imaging feature of inflamma myfibroblastic tumor and to improve the diagnostic knowledge of it. Methods Clinical data about 7 patients with inflamma myfibroblastic tumor admitted to our hospital were retrospectively analyzed with its related literature review. Results The middle age of the 7 patients （3 males and 4 fe- males） with inflamma myfibroblastic tumor included in this study was 42 years. All were the single focus and different place had different main clinical manifestations in patients. CT showed tissue density lump with uniformity or nonuniform density, almost had the boundary of the clear. CT enhanced scan showed obvious or nonuniform enhancement. Except lung case, six case showed different degree of wrapping the blood vessel, Artery were non apparent abnormality and vein was obviously crush. Conclusion Inflamma myfibroblastic tumor has no specific imaging manifestations, and is diagnosed according to its pathology. CT can offer the relative information of focus, so that it can help for the treatment and follow- up survey.
