摘　　要：目的探讨原发性卵巢平滑肌瘤(POL)的磁共振成像(MRI)表现,提高对该病的认识。方法回顾性分析广州市花都区人民医院2006年9月至2018年8月经手术病理证实的POL患者4例的资料,分析其MRI表现及病理特点。结果4例POL均为单侧卵巢单发肿块,类圆形,包膜完整,边界清楚;3例实性,1例囊实性;3例瘤体较大者见包膜下积液;典型MRI表现为T1WI呈等/稍低信号,T2WI、DWI呈低信号,增强扫描实性部分与子宫同步强化;不典型者T2WI可以出现不同程度高信号囊变,囊变区不强化。POL内部信号及病理学特征与子宫平滑肌瘤相似。结论该研究成果具有显著创新性及科学性,MRI对POL的诊断及鉴别诊断具有重要意义。Objective To investigate magnetic resonance imaging(MRI)findings of primary ovarian leiomyoma(POL)and improve the understanding of the disease.Methods The clinical data of four cases of POL confirmed by surgical pathology who received treatment in Huadu District People's Hospital between September 2006 and August 2018 were retrospectively analyzed.MRI manifestations and pathological features of POL were analyzed.Results In four cases,POL occurred in unilateral ovarium and appeared to be a single quasi round mass with complete capsule and clear boundary.A solid mass was observed in three cases and a cystic solid mass in one case.Subcapsular effusion was observed in three cases with a relatively large tumor body.Typical MRI findings were iso-intensity or slight hypo-intensity signal on T1WI,hypo-intensity signal on T2WI and diffusion-weighted images.The solid part on enhanced scan was enhanced synchronously with the uterus.Atypical T2WI findings included cystic changes as shown by varying degrees of hyper-intensity signal,and the cystic change area was not enhanced.The internal signal and pathological features of POL were similar to those of uterine leiomyoma.Conclusion The research results are highly innovative and scientific.MRI is of great significance in the diagnosis and differential diagnosis of POL.
