【摘要】：目的:探討原發(fā)性脾血管肉瘤(PSA)的超聲、CT表現(xiàn)及病理特點(diǎn)。方法:回顧性分析2005年-2015年經(jīng)手術(shù)及病理證實(shí)的7例PSA的臨床、CT及超聲表現(xiàn),并與病理結(jié)果進(jìn)行對(duì)照研究。結(jié)果:7例PSA的影像學(xué)表現(xiàn)可以分為3型,Ⅰ型為單發(fā)病灶(n=1),CT平掃呈類(lèi)圓形稍低密度灶,增強(qiáng)掃描邊緣強(qiáng)化;脾臟病灶超聲呈類(lèi)圓形低回聲。Ⅱ型為多發(fā)、分離病灶(n=5),其中平掃4例表現(xiàn)為稍低密度,其中3例超聲檢查,1例表現(xiàn)為低回聲、回聲不均,1例病灶表現(xiàn)為高低混雜回聲,1例未發(fā)現(xiàn)明確病灶,增強(qiáng)CT掃描4例為邊緣強(qiáng)化,1例表現(xiàn)為結(jié)節(jié)狀強(qiáng)化。Ⅲ型為彌漫性病變(n=1),平掃為多發(fā)大小不等類(lèi)圓形稍低密度,增強(qiáng)部分邊緣強(qiáng)化,部分結(jié)節(jié)狀強(qiáng)化;超聲表現(xiàn)為脾大,回聲粗。病理表現(xiàn)4例為彌漫性、不典型的血管內(nèi)皮細(xì)胞蜂窩狀或海綿狀排列,2例鏡下見(jiàn)裂隙血管及乳頭狀結(jié)構(gòu),1例表現(xiàn)為紡錘狀的內(nèi)皮細(xì)胞增殖排列形成血管間隙。結(jié)論:PSA的臨床特點(diǎn)、影像學(xué)及病理表現(xiàn)有一定的特異性,認(rèn)識(shí)其影像學(xué)及病理特征對(duì)減少誤診有重要意義。
[Abstract]:Objective: to investigate the CT features and pathological features of primary splenic angiosarcoma (PSA). Methods: Ct and ultrasound findings of 7 cases of PSA proved by surgery and pathology from 2005 to 2015 were retrospectively analyzed and compared with pathological findings. Results the imaging findings of 7 cases of PSA could be divided into three types. Type I was a single lesion, which showed a slightly lower density lesion on plain CT scan, enhanced edge enhancement, and the splenic lesions showed round hypoechoic echo on ultrasound, and multiple lesions in type 鈪，
