| 目的 探讨MRI对原发性闭经的诊断价值。方法 回顾性分析16例经手术证实病因的原发性闭经患者的盆部MRI资料，并与手术结果对照。结果 手术证实16例原发性闭经患者包括1例阴道下1/3闭锁、12例苗勒管畸形（MDA）、1例完全性雄激素不敏感综合征（AIS）和2例先天性肾上腺皮质增生（CAH）。14例（14/16，87.50%）术前MRI诊断与术后诊断相符。2例（2/16，12.50%）术前MRI误、漏诊，均为MDA患者，其中1例术中见2个始基子宫，术前MRI漏诊左侧始基子宫，另1例合并宫颈缺如，术前MRI误诊为阴道闭锁。结论 通过MRI可较为准确地观察阴道、子宫、卵巢结构及发育情况，对原发性闭经患者术前行MR检查有助于及时诊断。 |

| Objective To evaluate the value of MRI in diagnosis of primary amenorrhea. Methods Pelvic MRI data of 16 patients with primary amenorrhea confirmed by pathology were retrospectively analyzed. And the MRI results were compared with intraoperative findings. Results Sixteen patients with primary amenorrhea included 1 case of lower part vagina atresia, 12 cases of Mullerian duct abnormalities (MDA), 1 case of complete androgen insensitivity syndrome (AIS) and 2 cases of congenital adrenal cortex hyperplasia (CAH). Totally 14 cases (14/16, 87.50%) were diagnosed accurately by preoperative MRI. Another 2 cases (2/16, 12.50%) were misdiagnosis and missed diagnosis in MRI. Both of the two error diagnostic cases were MDA patients. One of them existed two primordial uteri founded in operation, while MRI missed the left primordial uterus. The other 1 case was absence of cervix uteri confirmed postoperatively, but misdiagnosed as vagina atresia by preoperative MRI. Conclusion The references obtained by MRI such as the structure and development of vagina, uterus and ovaries, are helpful to early diagnose primary amenorrhea before operation. |
