Abstract:
A man in his 60s with hyperamylasemia underwent contrast-enhanced computed tomography, which revealed masses in his pelvic cavity on the right side and in the left axilla. Hence, a detailed examination was performed. Upon performing Sonazoid® (perfluorobutane) contrast-enhanced ultrasound, it was discovered that the right-sided pelvic cavity mass exhibited centripetal contrast-enhancement right from the early stage. Subsequently, the contrast material disappeared from the center and was washed out in the postvascular phase. The mass was suspected to be caused by vascular malformations. The right-sided pelvic cavity mass was excised, and upon histopathological examination, it was detected to be composed of capillary malformations. Thus, it was found that Sonazoid® contrast-enhanced ultrasound examination could aid in diagnosing retroperitoneal masses.
摘要:
一名60多岁患有高淀粉酶血症的男子接受了对比增强计算机断层扫描,这显示了他右侧和左侧腋窝的盆腔肿块。因此,进行了详细的检查。在进行Sonazoid®(全氟丁烷)对比增强超声检查时,发现右侧盆腔肿块从早期就表现出向心对比增强。随后,造影剂从中心消失,并在血管后阶段被洗掉。怀疑肿块是由血管畸形引起的。切除右侧盆腔肿块,经过组织病理学检查,它被检测到是由毛细血管畸形组成的。因此,研究发现,Sonazoid®超声造影检查有助于诊断腹膜后肿块.
