目的 旨在探讨经腹壁超声与多 层螺旋CT(MSCT)对女性盆腔囊性病变诊断 及鉴别诊断价值。方法 将2014年1月至 2017年12月于我院就诊治疗的76例女性盆 腔囊性病变患者作为研究对象，收集所有 患者相关影像学资料，且以手术过程病 理活检结果为标准，分析不同检查方式 对女性盆腔囊性病变的正确诊断率。结 果 MSCT诊断盆腔囊性病变的正确符合率 为95.35%，显著高于经腹壁超声正确诊断 率(83.72%)(P<0.05)；在腹壁超声检查中 盆腔包虫主要呈现较厚囊壁和少量条状血 流信号；卵巢囊肿未见回声，囊壁乳头状 区域可见彩色血流信号；子宫平滑肌瘤可 见低回声，且边界尚清晰，存在少量血流 信号；而在MACT平扫中，盆腔包虫未见异 常，卵巢囊肿平扫见囊壁表示薄且均匀， 其中18例可见明显钙化，且呈沙砾状，而 子宫平滑肌瘤可见巨大混杂密度，且向下 腹部突入，子宫因肌瘤压迫可移位于键 侧，经进一步增强扫描中盆腔包虫囊壁无 钙化但存在轻度强化，且呈弧线形，卵巢 囊肿可在在囊壁增厚以及突起部分可见明 显强化表现，而子宫平滑肌瘤在动脉期呈 现不同程度强化表现，而在静脉期和延 迟期均持续呈现不均匀强化。结论 MSCT 在诊断女性盆腔囊性病变中的优势更为明 显，诊断正确率更高，更有利于提高女性 盆腔囊性病变的定性诊断率。

Objective To investigate the value of transabdominal ultrasonography and multi-slice spiral CT (MSCT) in the diagnosis and differential diagnosis of female pelvic cystic lesions. Methods 76 patients with female pelvic cystic lesions who were treated in our hospital from January 2014 to December 2017 were enrolled in the study. All relevant imaging data of patients were collected.The postoperative results of biopsy were used as the diagnostic criteria, and the diagnostic accuracy of different examination for female pelvic cystic lesions was analyzed. Results The correct rate of MSCT in the diagnosis of pelvic cystic lesions was 95.35%, which was significantly higher than that of transabdominal ultrasonography (83.72%) (P<0.05). In the abdominal wall ultrasonography, the pelvic echinococcosis mainly showed thicker vesicle wall and a small amount of streak blood stream signals. There is no echo in the ovarian cyst, and color blood stream signals was seen in the papillary region of the capsule wall. Leiomyoma of uterus can be seen with low echo, with clear boundary, and there is a small amount of blood stream signals;In the MACT plain scan, the pelvic echinococcosis showed normality. In the plain scan of ovarian cysts, the wall was thin and even, and 18 of them showed obvious calcification and were gravel-like. Leiomyoma of uterus can be seen with a large mixed density and protrudes into the lower abdomen. The uterus can be moved to the side of the bond due to compression of fibroid. After further enhancement of scan, the cyst wall of pelvic echinococcosis is not calcification, with slight enhancement and it was curved. Ovarian cysts can be seen with obvious enhancement in the thickening and the bulge of the cyst wall, while the leiomyoma of uterus exhibits different degrees of enhancement in the arterial phase, and continues to show uneven enhancement in the venous phase and the delayed phase. Conclusion The advantage of MSCT in the diagnosis of female pelvic cystic lesions is more obvious, and the diagnostic accuracy is higher, which is more beneficial to improve the qualitative diagnosis rate of female pelvic cystic lesions.
