螺旋CT诊断卵巢畸胎瘤的准确性评价

Spiral CT Diagnosis of Ovarian Teratoma the Accuracy of Evaluation

目的:分析卵巢畸胎瘤的螺旋CT影像特征。材料与方法:回顾性分析经手术及病理证实的卵巢畸胎瘤31例,均行螺旋CT检查。结果:31例卵巢畸胎瘤中,双侧附件的4例;右侧附件11例;左侧附件的15例:左侧附件伴有双角子宫畸形的1例。其特征性表现边界清楚,有完整包膜,以液性脂肪密度为主、漂浮物、钙化或牙齿和含有物质的混杂密度28例;液性脂肪密度和漂浮物为脂-液性面的2例;水样密度和极少量液性脂肪密度1例。结论:螺旋CT盆腔横断面平扫和增强诊断卵巢畸胎瘤具有特征性表现,有助于提高诊断的准确性。

Purpose： Analysis of ovarian teratoma spiral CT imaging features. Materials and Methods： Retrospective analysis confirmed by surgery and pathology of 31 cases of ovarian teratoma are spiral CT. Results： 31 eases Of ovarian teraroma in four cases Of bilateral attachment; the right sid of the annex to the 11 cases; 15 eases of the left Side of the annex; the left Side of the annex with double uterus malformation in 1 case. Characterized by a Clear expression of the border, there are complete capsule to liquid fat density malniy floats, calcification or teeth and mixed - density material eontaining 28 cases; liquid fat density and floating debris for the fat - liquid facial 2 cases; water sample density and a very small amount of liquid fat density in I case. Conclusion： The spiral CT scan of pelvic and enhanced cross - sectional diagnosis of ovarian teratoma with a characteristic performance, help to improve diagnostic accuracy.
