We retrieved sonographic images and videoclips, focusing on the detection of the lead vessel.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The presence of the lead vessel was detected in 11\/31 (35.4%) metastatic ovarian tumors, and in only two (0.01%) cases of primary ovarian carcinoma (<jats:italic>P<\/jats:italic> = 0.0001). At color Doppler analysis, metastatic ovarian lesions were characterized by significantly lower pulsatility index (<jats:italic>P<\/jats:italic> = 0.0001) and resistance index (<jats:italic>P<\/jats:italic> = 0.0001) values, and significantly higher peak systolic velocity (<jats:italic>P<\/jats:italic> = 0.0002) and time\u2010averaged maximum velocity (<jats:italic>P<\/jats:italic> = 0.04) values, when compared with primary ovarian carcinomas. The lead vessel was detected in 11\/21 (52%) solid metastatic lesions and in no cases of multilocular or multilocular\u2010solid lesions (<jats:italic>P<\/jats:italic> = 0.008).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The lead vessel is a novel sonographic feature of vascular morphology in solid ovarian metastases. The more frequent observation of this feature in metastatic ovarian tumors compared with primary invasive ovarian carcinomas warrants further investigation in order to explore its potential role in the diagnosis of metastatic ovarian masses.
