静脉内平滑肌瘤病超声与CT特征

目的 观察静脉内平滑肌瘤病(IVL)的临床、超声与CT特征表现.方法 回顾性分析55例经术后病理证实的IVL患者的临床及影像学特征,对比超声、CT诊断IVL的准确率.结果 Ⅰ期IVL超声多表现为子宫肿物呈“蠕虫”或条索串珠样向宫旁延伸,血流信号丰富;CT多表现为子宫或盆腔低密度肿物,伴子宫静脉或卵巢静脉内肿物.Ⅱ～Ⅳ期...

Ultrasonic and CT features of intravascular leiomyomatosis

Objective To observe ultrasonic and CT features of intravascular leiomyomatosis(IVL).Methods Data of 55 patients with pathologically confirmed IVL were retrospectively analyzed,the clinical and imaging features were observed,and the accuracy of ultrasound and CT for diagnosing IVL were compared.Results The ultrasonic characteristics of stageⅠIVL were uterine masses“worm”like or string beaded extending to the side of the uterus,with abundant blood flow within the masses.CT showed low-density masses of uterus or pelvis,accompanied by masses in uterine veins or ovarian veins.For stageⅡ-ⅣIVL,the ultrasonic findings were characterized by the presence of ribbon-shaped mass in the genital vein,iliac vein,inferior vena cava,right cardiac and even pulmonary artery along the vein with blood flow signals,which on enhanced CT present as uneven enhancement of the mass like“loofah sponge”.The diagnostic accuracy of CT and ultrasound for IVL was 58.18%and 49.09%,respectively,of CT was higher than of ultrasound(P<0.05).The diagnostic accuracies of ultrasound and CT for stageⅡ-ⅣIVL were both higher than that for stageⅠIVL(both P<0.05).The diagnostic accuracy of IVL raised to 74.55%with combination of ultrasound and CT.Conclusion The imaging findings of IVL had certain characteristics.Combing ultrasound and CT could significantly improve the diagnostic accuracy of IVL.
