盆腔异位妊娠CT表现及与MRI对比分析

Comparison Analysis on CT and MRI Findings of Pelvic Ectopic Pregnancy

目的探究盆腔异位妊娠的CT及磁共振成像(MRI)表现。方法回顾性分析我院收治的32例行CT和/或MRI检查的异位妊娠患者的临床资料,所有患者均经手术证实,其中18例行CT检查,14例行MRI检查。结果 32例患者中输卵管妊娠18例(56.25%),切口妊娠8例(25.00%),卵巢妊娠4例(12.50%),宫角妊娠2例(6.25%);异位妊娠CT及MRI表现为子宫内膜外囊性或混杂信号肿块,增强扫描呈边缘强化或不均匀强化;18例行CT检查的病例术前明确诊断12例,未能明确定性3例,误诊3例;14例行MRI检查的病例术前明确诊断10例,未能准确定性2例,误诊2例。结论不同部位异位妊娠的CT、MRI表现均有一定特征,临床上可结合停经史、临床症状及实验室指标明确诊断。

Objective To investigate the CT and magnetic resonance imaging(MRI) findings of pelvic ectopic pregnancy. Methods The clinical data of 32 patients with ectopic pregnancy who underwent CT and/or MRI examination in the hospital were analyzed retrospectively. All patients were confirmed by surgical pathologyy. Among them, 18 accepted CT examination and 14 cases accepted MRI examination. Results Among the 32 patients, there were 18 cases(56.25%) with tubal pregnancy, 8 cases(25.00%) with incision pregnancy, 4 cases(12.50%) with ovarian pregnancy and 2 cases(6.25%) with uterine horn pregnancy. The CT and MRI findings of ectopic pregnancy showed endometrial external cystic or mixed signal masses. The enhanced scan showed marginal enhancement or uneven enhancement. In the 18 cases undergoing CT examination, there were 12 cases diagnosed as ectopic pregnancy before operation, three cases could not be determined and 3 cases were misdiagnosed. Among the 14 cases who accepted MRI examination, 10 cases were diagnosed before operation, 2 cases could not be determined and 2 cases werd misdiagnosed. Conclusion The CT and MRI findings of ectopic pregnancy in different parts have certain characteristics, which can be diagnosed by combining the history of menopause, clinical symptoms and laboratory indicators.
