超声对卵巢转移性印戒细胞瘤的诊断及临床价值

目的：探讨卵巢转移性印戒细胞瘤的声像图特征。材料与方法：应用彩色多普勒对14例均经组织病理学证实的卵巢转移性印戒细胞瘤进行观察及对照分析。结果：在盆腔内检测到边界不清，形态不规则，内部回声不均质，以低、等回声和囊实混合性回声团块，其中2例低回声，5例等回声，7例囊实混合性回声。病灶位置左侧1例，右侧5例，双侧8例，10例病灶内均见有彩色血流信号，频谱的特点为高速低阻力模型。结论：二维超声与极色多普勒相结合，有助于对卵巢转移性印戒细胞瘤的诊断并提供了可靠的依断依据及临床价值。

Diagnostic value ofultrasonography in oval metastatic signet ring -cell cancer

Objective: To evaluate the value of sonography in the diagnosisof metastatic signet ring - cell cancer of ovary. Methods: Fourteen cases of signet ring-cell cancer confirmed by pathology were examined by sonography. Results: Sonogram showed the tumor mass had indistinct margin, irregular in shape, heterogeneous with a mixture cystic and solid echogeneity. In which 2 cases were hypoechoic, 5 cases were isoechoic. 7 cases showed cystic and solid echogenity. The site of tumor: lcase was located on left side. 5 cases on right side, 8 cases were bilateral. There were color blood flow signal in 10 cases. The frequency spectrum is characterized by high speed low resistance. Conclusions: The combination of 2D color Doppler sonography is helpful in the diagnosis of metastatic signet ring - cell cancer of the ovary.
