【摘要】：目的:分析不同原发部位炎性肌纤维母细胞瘤影像学特征,提高对炎性肌纤维母细胞瘤影像特征的认识,为临床正确诊断炎性肌纤维母细胞瘤提供依据。方法:收集广西医科大学第一附属医院2005年11月至2015年11月经病理确诊为炎性肌纤维母细胞瘤15例患者影像资料,对患者影像资料进行回顾性分析。结果:共入组我院10年期间共15例IMT患者,中位年龄28岁(4岁-73岁)。其中男性9例,女性6例,男性多于女性。其中肺部IMT 6例,胃部2例,结肠、脑、乳腺、心包、肝脏、肾脏、前列腺IMT患者各1例。病灶较大,其中直径大于3cm患者12例,平均直径5.8cm。影像学多表现为单发(14/15)、边界清楚(11/15)、密度均匀(9/14)病灶,少数可表现为多发、边界不清,有时酷似恶性肿瘤。肺是IMT最好发部位(6/15),左下肺多见(3/6)。病灶密度在肺部表现为高密度、软组织肿块影,肺外均表现为低密度或等密度软组织肿块影。胃肠道的IMT最常见的部位是胃(2/3),好发于胃大弯侧(2/2)。所有行增强扫描患者均表现为不同程度强化,病灶强化形式没有固定规律。MRI扫描均表现为长或等T1、T2信号。结论:IMT是一种罕见的实体软组织肿瘤,好发于肺,影像学表现与其它软组织肿瘤表现相似,多表现为单发、边界清楚、密度均匀,但病灶表现变化多样,有时与恶性肿瘤或其它软组织肿瘤难以区分,确诊有赖于病理诊断。
[Abstract]:Objective: to analyze the imaging features of inflammatory myofibroblastoma in different primary sites, and to improve the understanding of the imaging features of inflammatory myofibroblastoma, so as to provide the basis for clinical diagnosis of inflammatory myofibroblastoma. Methods: the imaging data of 15 patients with inflammatory myofibroblastoma from November 2005 to November 2015 in the first affiliated Hospital of Guangxi Medical University were collected and analyzed retrospectively. Results: there were 15 patients with IMT in our hospital during 10 years. The median age was 28 years old, 4 ~ 73 years old. Among them, 9 cases were male, 6 cases were female, male was more than female. There were 6 cases of lung IMT, 2 cases of stomach, 1 case of colon, brain, breast, pericardium, liver, kidney and prostatic IMT. The lesions were larger, including 12 patients with diameter larger than 3cm, with an average diameter of 5.8 cm. Most of the imaging findings were solitary 14 / 15, with clear boundaries of 11 / 15, homogeneous density of 9 / 14) lesions, a few of which were multiple, unclear borders, and sometimes resembled malignant tumors. The lung is the best place for IMT to be 6 / 15, and the lower left lung is more than 3 / 6. The focus density was high density in lung, soft tissue mass shadow, and low density or equal density soft tissue mass shadow outside lung. The most common site of IMT in the gastrointestinal tract is 2 / 3 of the stomach, which occurs at 2 / 2 / 2 of the great curvature of the stomach. All the patients with enhanced MRI showed different degree of enhancement, and the pattern of enhancement was not fixed. MRI showed long or equal T 1 T 2 signal intensity. ConclusionTwenty IMT is a rare solid soft tissue tumor, which is prone to occur in the lung. The imaging findings are similar to those of other soft tissue tumors. Sometimes it is difficult to distinguish from malignant tumor or other soft tissue tumor, and the diagnosis depends on pathological diagnosis.
