Abstract:
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—Ⅲ in 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.
