Serous surface papillary borderline ovarian tumor (SSPBOT) is a distinct subtype of serous borderline ovarian tumor characterized by solid tissue deposition confined to the ovarian surface. Because SSPBOT is rare, there are few published reports on the ultrasonographic features of this condition. In this retrospective study, we investigated 12 cases of SSPBOT. Ultrasound imaging of SSPBOT showed grossly normal ovaries that were encased partially or wholly by tumor deposits that were confined to the surface, with clear demarcation between normal ovarian tissue and surrounding tumors. Color Doppler imaging demonstrated the 'fireworks sign' in all cases of SSPBOT, corresponding to an intratumoral vascular bundle originating from the ovarian vessels and supplying hierarchical branching blood flow to the surrounding tumor. No patient with ovarian high-grade serous carcinoma showed these morphological and Doppler features. In our series, the fireworks sign appeared to be a characteristic feature of SSPBOT that could facilitate correct identification of this tumor. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.
浆液性表面乳头状交界性卵巢肿瘤（SSPBOT）是浆液性交界性卵巢肿瘤的一种独特亚型，其特征是实性组织沉积局限于卵巢表面。由于SSPBOT较为罕见，关于这种疾病超声特征的已发表报告很少。在这项回顾性研究中，我们调查了12例SSPBOT。SSPBOT的超声成像显示卵巢大体正常，部分或全部被局限于表面的肿瘤沉积物包裹，正常卵巢组织与周围肿瘤之间界限清晰。彩色多普勒成像在所有SSPBOT病例中均显示出“烟花征”，这对应于起源于卵巢血管并向周围肿瘤提供分级分支血流的肿瘤内血管束。没有卵巢高级别浆液性癌患者表现出这些形态学和多普勒特征。在我们的系列研究中，烟花征似乎是SSPBOT的一个特征性表现，有助于正确识别这种肿瘤。© 2023国际妇产科超声学会。
