【摘要】:目的:探讨原发性脾血管肉瘤(PSA)的超声、CT表现及病理特点。方法:回顾性分析2005年-2015年经手术及病理证实的7例PSA的临床、CT及超声表现,并与病理结果进行对照研究。结果:7例PSA的影像学表现可以分为3型,Ⅰ型为单发病灶(n=1),CT平扫呈类圆形稍低密度灶,增强扫描边缘强化;脾脏病灶超声呈类圆形低回声。Ⅱ型为多发、分离病灶(n=5),其中平扫4例表现为稍低密度,其中3例超声检查,1例表现为低回声、回声不均,1例病灶表现为高低混杂回声,1例未发现明确病灶,增强CT扫描4例为边缘强化,1例表现为结节状强化。Ⅲ型为弥漫性病变(n=1),平扫为多发大小不等类圆形稍低密度,增强部分边缘强化,部分结节状强化;超声表现为脾大,回声粗。病理表现4例为弥漫性、不典型的血管内皮细胞蜂窝状或海绵状排列,2例镜下见裂隙血管及乳头状结构,1例表现为纺锤状的内皮细胞增殖排列形成血管间隙。结论:PSA的临床特点、影像学及病理表现有一定的特异性,认识其影像学及病理特征对减少误诊有重要意义。
[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,
