【摘要】：目的:分析不同原發(fā)部位炎性肌纖維母細(xì)胞瘤影像學(xué)特征,提高對炎性肌纖維母細(xì)胞瘤影像特征的認(rèn)識,為臨床正確診斷炎性肌纖維母細(xì)胞瘤提供依據(jù)。方法:收集廣西醫(yī)科大學(xué)第一附屬醫(yī)院2005年11月至2015年11月經(jīng)病理確診為炎性肌纖維母細(xì)胞瘤15例患者影像資料,對患者影像資料進(jìn)行回顧性分析。結(jié)果:共入組我院10年期間共15例IMT患者,中位年齡28歲(4歲-73歲)。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,結(jié)腸、腦、乳腺、心包、肝臟、腎臟、前列腺IMT患者各1例。病灶較大,其中直徑大于3cm患者12例,平均直徑5.8cm。影像學(xué)多表現(xiàn)為單發(fā)(14/15)、邊界清楚(11/15)、密度均勻(9/14)病灶,少數(shù)可表現(xiàn)為多發(fā)、邊界不清,有時酷似惡性腫瘤。肺是IMT最好發(fā)部位(6/15),左下肺多見(3/6)。病灶密度在肺部表現(xiàn)為高密度、軟組織腫塊影,肺外均表現(xiàn)為低密度或等密度軟組織腫塊影。胃腸道的IMT最常見的部位是胃(2/3),好發(fā)于胃大彎側(cè)(2/2)。所有行增強(qiáng)掃描患者均表現(xiàn)為不同程度強(qiáng)化,病灶強(qiáng)化形式?jīng)]有固定規(guī)律。MRI掃描均表現(xiàn)為長或等T1、T2信號。結(jié)論:IMT是一種罕見的實(shí)體軟組織腫瘤,好發(fā)于肺,影像學(xué)表現(xiàn)與其它軟組織腫瘤表現(xiàn)相似,多表現(xiàn)為單發(fā)、邊界清楚、密度均勻,但病灶表現(xiàn)變化多樣,有時與惡性腫瘤或其它軟組織腫瘤難以區(qū)分,確診有賴于病理診斷。
[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.
