【摘要】：目的卵巢卵泡膜细胞瘤(OT)较少见,现探讨卵巢卵泡膜细胞瘤的MRI表现及病理特征。方法分析经病理证实的30例OT患者的MRI表现,并与其病理结果进行对照,分析病灶大小、囊实性与腹水的相关性。结果MRI平扫病灶实体T1WI均呈等低信号,T2WI呈低信号为主夹杂少量高信号21例,高信号为主2例,增强后早期病灶实性部分多呈轻度强化,延迟后强化程度略增加。20例MRI发现不同程度的腹盆腔积液,2例伴胸腔积液。病理示病灶囊性变和MRI表现的囊变信号灶数目、形态基本一致,腹水程度和病灶大小无相关性(r=0.29,p＞0.05),肿瘤囊实性变与腹水程度相关性亦无统计学意义(r=0.25,P＞0.05),病灶MRI囊实性改变与病理学细胞组成差异无统计学意义(x2=0.67,P＞0.05)。结论卵泡膜细胞瘤T2WI低信号的特征及增强模式一定程度上可反映其病理特征,对诊断有一定的特异性,有助于该肿瘤的诊断与鉴别诊断。
[Abstract]:Objective to investigate the MRI features and pathological features of ovarian follicular cell tumor (OTC). Methods the MRI findings of 30 cases of OT proved by pathology were analyzed and compared with the pathological results. Results on MRI plain scan, the mass of the lesions showed low signal intensity on T _ 1WI, low signal intensity on T _ 2WI and a small amount of high signal intensity in 21 cases, and high signal intensity in 2 cases. After enhancement, the solid parts of the lesions showed mild enhancement in the early stage of enhancement. The degree of enhancement was slightly increased in 20 cases of MRI. 2 cases with pleural effusion were found with different degrees of abdominal and pelvic effusion. Pathological findings showed that the number of cystic lesions and the signal number of cystic changes in MRI were basically the same. There was no correlation between the degree of ascites and the size of the lesion. There was no significant correlation between the degree of cystic and solid neoplasms and the degree of ascites, and there was no significant difference between the changes of the cystic and solid degree of MRI and the pathological cell composition (P > 0.05), and there was no significant difference between the degree of ascitic fluid and the degree of ascites (P > 0.05). Conclusion the hypointensity and enhancement pattern of follicular cell tumor on T _ 2WI can reflect its pathological features to some extent, and have some specificity in diagnosis, which is helpful to the diagnosis and differential diagnosis of the tumor.
