摘要

目的：探讨脾脏局灶性病变的超声造影特征及良恶性病变的差异。方法：回顾性分析我院经手术或经皮穿刺活检病理确诊的24例脾脏局灶性病变患者的超声声像图特征，并比较良恶性病灶最大径、病灶数目、回声、边界、形态、动脉期及静脉期增强程度、动脉期增强病灶3min内有无明显廓清方面有无差异。结果：共纳入24例患者的24个脾脏局灶性病变，包括15个良性病灶和9个恶性病灶。3个良性病灶超声造影表现为始终无增强，余 21个病灶均有增强，其中良性12个，恶性9个。动脉期增强病灶3min内有无明显廓清方面比较差异有统计学意义(P<0.05)，良恶性病灶最大径、病灶数目、回声、边界、形态、动脉期及静脉期增强程度等指标比较差异均无统计学意义。结论：脾脏局灶性病变具有一定超声造影特征，其中造影剂3min内是否有明显廓清对鉴别良恶性有借鉴意义。

Abstract

Objective ：To investigate the ultrasonographic features of focal splenic lesions on contrast-enhanced ultrasound (CEUS) and the difference between benign and malignant lesions. Methods： The ultrasonographic characteristics of 24 patients with focal splenic lesions diagnosed by surgery or percutaneous biopsy in our hospital were retrospectively analyzed. Ultrasonographic characteristics of the benign and malignant focal splenic lesions were compared including the maximum diameter

number of lesions

echo

margin

shape

the enhancement degree in arterial phase and venous phase

and the presence of obvious wash-out within 3min after contrast agent injection. Results ：A total of 24 focal splenic lesions were included in 24 patients

including 15 benign lesions and 9 malignant lesions. Three benign lesions showed no enhancement on CEUS，the remaining 21 lesions showed enhancement， including 12 benign and 9 malignant lesions. The presence of obvious wash-out within 3min after contrast agent injection were statistically different in benign and malignant focal splenic lesions (P<0.05)

while there were no statistically significant differences in the maximum diameter

number of lesions

echo

margin

shape

the enhancement degree in arterial phase and venous phase. Conclusion ：Focal splenic lesions have certain CEUS characteristics

and the presence of clear wash-out of contrast agent within 3min is helpful for differentiating benign from malignant lesions.
