目的探讨脾脏硬化性血管瘤样结节性转化(SANT)的超声表现。方法回顾性分析7例经手术病理证实为SANT患者的临床、超声资料并复习相关文献,分析、总结SANT的超声表现。结果 7例均为单发的类圆形肿块(7/7),边界清楚4例(4/7),边界不清3例(3/7),等回声2例(2/7),低回声5例(5/7),中心星芒状强回声3例(3/7),中心线样强回声4例(4/7),中心点状钙化1例(1/7),假包膜2例(2/7)。CDFI显示:7例(7/7)病灶周边均见点状或线样血流信号。结论 SANT是一种罕见的脾脏良性病变,超声表现具有一定的特征,认识这些特征有助于提高该病的诊断。
Objective To investigate the ultrasound findings of splenic sclerosing hemangioma-like nodular transformation (SANT). Methods The clinical and ultrasonographic data of 7 patients with SANT confirmed by surgery and pathology were retrospectively analyzed. The related literatures were reviewed, and the ultrasound findings of SANT were analyzed. Results All the 7 cases were solitary round lumps (7/7). The border was clear in 4 cases (4/7), the border was unclear in 3 cases (3/7), and the echoes in 2 cases (2/7) Echoes in 5 cases (5/7), center stellate-shaped hyperechoic echo in 3 cases (3/7), central line-like hyperechoic in 4 cases (4/7), central punctate calcification in 1 case (1/7) 2 cases (2/7). CDFI showed that punctate or line-like blood flow signals were observed in all 7 cases (7/7) of the lesions. Conclusions SANT is a rare benign splenic lesion. Ultrasound has certain features. Recognition of these features helps to improve the diagnosis of the disease.
