【摘要】：目的观察粒细胞肉瘤(GS)的影像学特征。方法回顾性分析27例经病理证实的GS患者的影像学资料,11例接受CT检查,其中4例接受增强扫描;9例接受MR平扫,其中7例接受动态增强扫描;6例接受超声检查;4例接受FDG PET/CT检查。结果 27例GS中,14例为白血病性GS,5例孤立性GS,8例未知分型;15例多发,12例单发,共计40个病灶,其中软组织GS 13个,淋巴结GS 12个,胸腹膜及胃肠道GS 5个,生殖系统GS 4个,中枢神经系统GS 3个,骨及骨膜GS 3个。40个病灶中,29个形态不规则,27个边界不清;CT扫描11例,呈等或略低密度,病灶中心CT值均较外周稍低,4例增强后均明显强化;MR扫描9例,DWI显示均明显弥散受限,8例呈等T1等T2信号,T2WI上病灶中心信号强度较外周稍低,7例动态增强中6例呈速升缓降型。PET/CT检查4例,病灶均代谢活跃,2例见全身骨髓弥漫性代谢活跃;超声检查6例,均呈低回声,2例可见血流信号。结论 GS的影像学表现具有一定特征性,结合临床病史有助于做出初步诊断。
[Abstract]:Objective to observe the imaging features of granulocytic sarcoma (GS). Methods the imaging data of 27 patients with pathologically proved GS were retrospectively analyzed. 11 cases received CT examination, 4 cases received enhanced scan, 9 cases received MR plain scan, 7 cases received dynamic enhanced scan, 6 cases received ultrasound examination. FDG PET/CT was performed in 4 cases. Results of the 27 cases of GS, 14 cases were leukemia GS,5, 14 cases were isolated GS,8. 15 cases were multiple, 12 cases were single, a total of 40 lesions, including soft tissue GS 13, lymph node GS 12, pleural and gastrointestinal tract GS 5, reproductive system GS 4, central nervous system GS 3, bone and periosteal GS 3. 29 forms were irregular and 27 boundaries were unclear; CT scan showed isodensity in 11 cases, CT value in the center of the lesion was lower than that in the peripheral area, and in 4 cases, the enhancement was obvious after enhancement. MR scan showed obvious diffusion limitation in 9 cases, iso-T 1 isointensity in 8 cases, central signal intensity on T2WI was slightly lower than that on peripheral area, and 6 cases showed rapid ascending and slowly descending type in 7 cases of dynamic contrast enhancement. PET/CT examination showed active metabolism in 4 cases. Diffuse metabolism of bone marrow was found in 2 cases. Ultrasonic examination showed hypoechoic in 6 cases and blood flow signal in 2 cases. Conclusion the imaging findings of GS are characteristic, and the combination of clinical history is helpful to make a preliminary diagnosis.
