【摘要】：目的觀察粒細(xì)胞肉瘤(GS)的影像學(xué)特征。方法回顧性分析27例經(jīng)病理證實(shí)的GS患者的影像學(xué)資料,11例接受CT檢查,其中4例接受增強(qiáng)掃描;9例接受MR平掃,其中7例接受動(dòng)態(tài)增強(qiáng)掃描;6例接受超聲檢查;4例接受FDG PET/CT檢查。結(jié)果 27例GS中,14例為白血病性GS,5例孤立性GS,8例未知分型;15例多發(fā),12例單發(fā),共計(jì)40個(gè)病灶,其中軟組織GS 13個(gè),淋巴結(jié)GS 12個(gè),胸腹膜及胃腸道GS 5個(gè),生殖系統(tǒng)GS 4個(gè),中樞神經(jīng)系統(tǒng)GS 3個(gè),骨及骨膜GS 3個(gè)。40個(gè)病灶中,29個(gè)形態(tài)不規(guī)則,27個(gè)邊界不清;CT掃描11例,呈等或略低密度,病灶中心CT值均較外周稍低,4例增強(qiáng)后均明顯強(qiáng)化;MR掃描9例,DWI顯示均明顯彌散受限,8例呈等T1等T2信號(hào),T2WI上病灶中心信號(hào)強(qiáng)度較外周稍低,7例動(dòng)態(tài)增強(qiáng)中6例呈速升緩降型。PET/CT檢查4例,病灶均代謝活躍,2例見(jiàn)全身骨髓彌漫性代謝活躍;超聲檢查6例,均呈低回聲,2例可見(jiàn)血流信號(hào)。結(jié)論 GS的影像學(xué)表現(xiàn)具有一定特征性,結(jié)合臨床病史有助于做出初步診斷。
[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.
