【摘要】：目的:分析卵巢冠囊肿的MRI表现,提高术前诊断准确性。方法:回顾性研究经手术和病理证实的50例卵巢冠囊肿患者的MRI图像,分析病灶部位、大小、形态、管壁、分隔厚度、囊液信号、增强表现及其与卵巢的关系等影像学特征。结果:50例患者共54个卵巢冠囊肿,MRI检出41个(76%),其中囊肿同侧见相邻或分开的正常或病变卵巢25个(61%);囊肿边界清晰、壁薄(41/41,100%,平均厚度1.5±0.3mm)、单房(39/41,95%)、囊液信号均匀如水(41/41,100%);囊肿因张力低而形态略欠规则的类圆形或类椭圆形(20/41,49%);最大径大于2.0cm的囊肿易误诊(25/30,83%),小于2.0cm者易漏诊(11/11,100%)。结论:卵巢冠囊肿的MRI表现有一定特征性,显示病灶同侧卵巢或卵巢病变为诊断的重要征象。
[Abstract]:Objective: to analyze the MRI findings of ovarian coronal cysts and to improve the accuracy of preoperative diagnosis.Methods: the MRI images of 50 patients with ovarian coronal cyst confirmed by surgery and pathology were retrospectively studied. The location, size, shape, wall, thickness of septum, signal of cystic fluid, enhanced findings and their relationship with ovary were analyzed.Results of 54 ovarian coronal cysts in 50 cases, 41 cases were detected by MRI. 25 normal or diseased ovaries were found in the same side of the cyst, and the boundary of the cyst was clear.The mean thickness was 1.5 卤0.3 mm, and the cyst fluid signal was as uniform as 41% 41 100%. The cyst had a slightly irregular shape due to low tension, and the shape of the cyst was slightly irregular. The largest diameter of the cyst larger than 2.0cm was misdiagnosed by 25% 3083%, and the diameter of the cyst was smaller than that of the 2.0cm group.Conclusion: the MRI features of ovarian coronal cysts are characteristic, and the ipsilateral ovarian or ovarian lesions are important signs in diagnosis.
