摘要
目的:分析卵巢多房囊性病变的MRI误诊原因。方法:回顾性分析14例经手术病理证实的卵巢多房囊性病变的MRI及临床资料。结果:14例多房囊性病变中卵巢子宫内膜异位囊肿7例,多呈T1WI、T2WI高信号及大房周围多个小囊表现,3例可见液-液分层,1例术前被误诊为粘液性囊腺瘤;输卵管卵巢脓肿2例,呈病灶周围炎性及厚壁明显强化表现,术前均被误诊为卵巢肿瘤性病变;卵巢甲状腺肿1例,表现为多房囊实性病灶、实性部分及包膜明显强化,术前被误诊为囊腺癌;囊腺瘤/癌4例,术前MRI诊断无误。结论:MRI能清楚显示卵巢多房性病变,由于影像科医生对这些疾病尤其部分少见病的认识相对不足,常常导致误诊;在全面分析病变MRI信号特点的同时,加强业务知识更新,密切结合临床,很多误诊是可以避免的。
Objective:To study the causes of misdiagnosis by MRI in ovarian multilocular lesions. Methods:The MRI and clinical materials of fourteen cases of ovarian multilocular lesions confirmed by pathology, were retrospectively analyzed. Results:In the 14 cases of multilocular lesions,ovarian endometriosis cysts (n: 7) showed high signals on T1 WI and T2 WI,and multiple small follicles around a big cyst and liquid-liquid levels in 3 cases. Among the 7, one was misdiagnosed as mucinous cystadenoma before operation. Ovarian abscess (n=2) showed inflammatory manifestations around the lesions and thickened wall,both of the 2 cases were misdiagnosed as ovarian tumor before operation. Struma ovarii 1 case (n 1) showed multilocular cystic lesion and enhancement of solid part,it was misdiagnosed as cystic carcinoma before operation. Cystadenoma/carcinoma 4 cases (n=4), there was no misdiagnosis. Conclusions:MRI can show the ovarian multilocular lesions clearly. Some rare diseases have characteristic manifestation on MRI. Because of the relative insufficient knowledge to these diseases,misdiagnosis is common. In daily work, many cases of misdiagnosis can be avoided by the update of professional knowledge,close combining with clinical symptoms and careful analysis of MRI signals.
