摘　　要：目的 观察腹部单发包块型淋巴瘤常规彩色多普勒超声(CDU)及超声造影(CEUS)表现。方法 回顾性分析32例接受CDU检查并经病理证实的腹部单发包块型淋巴瘤患者,其中28例同时接受CEUS;观察CDU所示病灶大小、内部回声、形态、边界、后方回声、血流信号、有无条索状及网格状高回声,以及有无血管包绕等征象,记录病灶CEUS增强分布、增强程度及增强模式。结果 CDU显示病灶多为低回声包块,内部回声欠均匀或不均匀(24/32,75.00%),形态欠规则或不规则(28/32,87.50%),边界清楚(26/32,81.25%),后方回声增强(28/32,87.50%),血流信号较丰富(AdlerⅡ~Ⅲ级,24/32,75.00%);25.00%(8/32)病灶可见血管包绕征及网状分隔征。CEUS显示造影剂多于动脉期快速进入病灶并达峰,动脉期多呈高增强(26/28,92.86%),达峰后快速廓清或缓慢消退,静脉期呈低增强;其强化多呈弥漫性(26/28,92.86%)、均匀(20/28,71.43%)分布,多数(22/28,78.57%)病灶内无液化坏死区。结论腹部单发包块型淋巴瘤CDU及CEUS表现具有一定特征性,或有助于早期诊断。Objective To observe conventional color Doppler ultrasound(CDU)and contrast-enhanced ultrasound(CEUS)manifestations of solitary abdominal mass-forming lymphoma.Methods Thirty-two patients with solitary abdominal mass-forming lymphoma confirmed by pathology who underwent CDU examination were retrospectively included,among them 28 patients also received CEUS.CDU manifestations of lesions were observed,including the size,echogenicity,shape,margin,posterior acoustic features,blood flow,as well as presence of cord-like and reticular high echogenicity and vascular encasement or not.The enhancement distribution,degree and pattern of lesion during CEUS were recorded.Results CDU showed that solitary abdominal mass-forming lymphomas lesions mainly appeared as hypoechoic masses with heterogeneous internal echogenicity(24/32,75.00%),irregular shape(28/32,87.50%),clear margin(26/32,81.25%)and posterior acoustic enhancement(28/32,87.50%),with rich blood flow(Adler gradeⅡ—Ⅲin 24 of 32,75.00%).Vascular encasement and reticular septation were noticed each in 8 cases(8/32,25.00%).During CEUS,peak intensity of contrast agents appeared rapidly in arterial phase,with common high enhancement(26/28,92.86%),which then washed out quickly after the peak or decreased slowly in arterial phase and low enhancement in venous phase.Diffuse distribution(26/28,92.86%),uniform enhancement pattern(20/28,71.43%)and absence of liquefied necrotic area inside(22/28,78.57%)were common findings.Conclusion CDU and CEUS manifestations of solitary abdominal mass-forming lymphoma had characteristics to a certain degree,which might be helpful to early diagnosis.
