To evaluate the value of transvaginal two-dimensional contrast-enhanced ultrasonography (2D-CEUS) in the diagnosis of atypical ovarian corpus luteum hematoma (AT-OCLH).
A prospective study was performed on 53 consecutive patients with suspected AT-OCLH, and the diagnostic results by transvaginal 2D-CEUS were statistically compared with the gold standard. The gold standard results were confirmed by surgical pathology or long-term follow-up.
The characteristic perfusion patterns of AT-OCLH in 2D-CEUS showed no contrast agent perfusion within the tumor mass, and the capsule wall showed rapid, annular, high enhancement perfusion; perfusion patterns could be classified into type Ia and type IIa. AT-OCLH can be distinguished from ovarian tumors based on perfusion characteristics and perfusion pattern type, which can be diagnosed based on the significantly stronger cystic wall perfusion intensity, earlier arrival time, and thicker cystic wall than nonluteal cystic foci (P<0.05). The sensitivity of 2D-CEUS for diagnosing AT-OCLH was 95.7%, with a specificity of 96.6%. A 2D-CEUS scoring system for AT-OCLH was established. Lesions with scores >17.5 were diagnosed as AT-OCLH.
2D-CEUS is an effective method for diagnosing AT-OCLH.
评估经阴道二维对比增强超声(2D-CEUS)在诊断非典型卵巢黄体血肿(AT-OCLH)中的价值。
对 53 例疑似 AT-OCLH 的患者进行前瞻性研究,将经阴道 2D-CEUS 的诊断结果与金标准进行统计学比较。金标准结果通过手术病理或长期随访证实。
2D-CEUS 中 AT-OCLH 的特征性灌注模式表现为肿瘤内无造影剂灌注,囊壁呈快速、环状、高增强灌注;灌注模式可分为 Ia 型和 IIa 型。基于灌注特征和灌注模式类型,AT-OCLH 可以与卵巢肿瘤区分开来,其囊壁的灌注强度、到达时间更早、囊壁更厚,均显著强于非黄体性囊性病灶(P<0.05)。2D-CEUS 诊断 AT-OCLH 的灵敏度为 95.7%,特异度为 96.6%。建立了 AT-OCLH 的 2D-CEUS 评分系统。评分>17.5 的病变被诊断为 AT-OCLH。
2D-CEUS 是诊断 AT-OCLH 的有效方法。
