【摘要】：目的 :分析睪丸精原細(xì)胞瘤的MSCT、MRI表現(xiàn),以提高對(duì)該病的認(rèn)識(shí)。方法 :回顧性分析9例經(jīng)手術(shù)病理證實(shí)的睪丸精原細(xì)胞瘤的MSCT、MRI表現(xiàn),觀察病灶的形態(tài)特征、密度、信號(hào)強(qiáng)度及強(qiáng)化特點(diǎn),5例行MSCT檢查,2例行MRI檢查,2例同時(shí)行MSCT和MRI檢查。結(jié)果:精原細(xì)胞瘤MSCT主要表現(xiàn)為密度相對(duì)均勻,增強(qiáng)掃描后腫瘤輕至中度強(qiáng)化。MRI主要表現(xiàn)為卵圓狀或分葉狀,信號(hào)均勻,T_2WI示更低信號(hào)條帶狀樣分隔,增強(qiáng)掃描時(shí)分隔強(qiáng)化程度高于其他實(shí)質(zhì)部分。結(jié)論 :睪丸精原細(xì)胞瘤影像學(xué)表現(xiàn)有一定特征性,MSCT、MRI檢查對(duì)睪丸精原細(xì)胞瘤的診斷與鑒別診斷有很大價(jià)值。
[Abstract]:Objective: to analyze MSCT MRI findings of testicular seminoma. Methods: the MRI findings of 9 cases of testicular seminoma proved by operation and pathology were retrospectively analyzed. The morphologic features, density, signal intensity and enhancement of the lesions were observed in 5 cases, and MRI was performed in 2 cases and MSCT and MRI were performed in 2 cases at the same time. Results: the density of seminoma was relatively homogeneous on MSCT. After contrast enhancement, the tumor showed oval or lobular enhancement. The signal intensity was even on T _ 2WI and showed lower signal intensity banded separation. The degree of separation and enhancement during enhanced scanning was higher than that in other substantive parts. Conclusion: MSCT MRI is of great value in the diagnosis and differential diagnosis of testicular seminoma.
