卵巢黄体破裂的CT诊断

CT diagnosis of ovarian corpus luteum rupture

目的探讨卵巢黄体破裂的CT表现及诊断价值。方法回顾性分析经手术病理证实的11例卵巢黄体破裂患者的临床及CT资料。结果患者均在月经周期后半期发病,其中右侧卵巢9例、左侧卵巢2例。CT表现为附件区有直径3.2～5.6 cm囊样病变(平均4.2 cm),2例圆形、9例椭圆形;2例囊液密度均匀如水(平扫CT值10～15 HU)、9例囊内密度不均匀(平扫CT值17～53 HU);可见局部囊壁连续性中断,病变周围和盆腔见密度较高的腹腔积液(CT值30～65 HU)。结论 CT可显示卵巢黄体破裂的特征,结合临床能及时作出诊断。

Objective To evaluate CT manifestation and diagnostic value in ovarian corpus luteum rupture.Methods Clinical data and CT imagings of 11 cases with ovarian corpus luteum rapture confirmed by surgical pathology were retrospectively analyzed.Results The onset began in the second half of the menstrual cycle in all patients,with 9 in the right ovary and 2 in the left ovary.CT displayed the cystic lesions in the adnexa area with the diameter of 3.2-5.6 cm(an average of 4.2 cm).Eleven cases showed the focal interruption of the cyst wall,with 2 round and 9 oval.The cystic liquid was homogeneous in 2 cases with the CT value of 10-15 HU,and the density of cystic contents was inhomogeneous in 9 cases with the CT value of 17-53 HU.The high-attenuation peritoneal fluid around cystic lesions and in the pelvic cavity were shown with CT value of 30-65 HU.Conclusion CT can be used to diagnose the ovarian corpus luteum rupture in the absence of ultrasound.
