【摘要】：目的卵巢卵泡膜細胞瘤(OT)較少見,現(xiàn)探討卵巢卵泡膜細胞瘤的MRI表現(xiàn)及病理特征。 方法分析經(jīng)病理證實的30例OT患者的MRI表現(xiàn),并與其病理結(jié)果進行對照,分析病灶大小、囊實性與腹水的相關(guān)性。 結(jié)果MRI平掃病灶實體T1WI均呈等低信號,T2WI呈低信號為主夾雜少量高信號21例,高信號為主2例,增強后早期病灶實性部分多呈輕度強化,延遲后強化程度略增加。20例MRI發(fā)現(xiàn)不同程度的腹盆腔積液,2例伴胸腔積液。病理示病灶囊性變和MRI表現(xiàn)的囊變信號灶數(shù)目、形態(tài)基本一致,腹水程度和病灶大小無相關(guān)性(r=0.29,p＞0.05),腫瘤囊實性變與腹水程度相關(guān)性亦無統(tǒng)計學(xué)意義(r=0.25,P＞0.05),病灶MRI囊實性改變與病理學(xué)細胞組成差異無統(tǒng)計學(xué)意義(x2=0.67,P＞0.05)。 結(jié)論卵泡膜細胞瘤T2WI低信號的特征及增強模式一定程度上可反映其病理特征,對診斷有一定的特異性,有助于該腫瘤的診斷與鑒別診斷。
[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.
