| 目的 观察原发性睾丸淋巴瘤（PTL）的MRI表现。方法 回顾性分析经病理证实的8例PTL患者的临床及MRI资料。结果 平扫MRI示8例患侧睾丸均形态失常，体积明显增大。病灶呈团块状，边界清，T1WI均呈低信号，3例其内可见点片状高信号；T2WI均呈等-低信号，信号不均匀。3例病变累及附睾及精索，睾丸与附睾分界欠清，信号不均，T2WI见精索多发纡曲条状高信号；3例合并睾丸鞘膜积液（其中累及附睾及精索1例）。延迟增强扫描病灶均呈明显不均匀强化，3例病灶内可见未强化区；8例病灶时间-强度曲线（TIC）均呈流出型（Ⅲ型）。8例DWI病灶实性部分均呈高信号，ADC图均呈低信号。结论 PTL的MRI表现有一定特征性，结合病灶平扫及动态增强特征有助于诊断PTL。 |

| Objective To investigate the MRI manifestations of primary testicular lymphoma (PTL). Methods Clinical and MRI data of 8 patients with pathologically confirmed PTL were retrospectively analyzed. Results Plain MRI showed morphological abnormalities of affected testis in all 8 cases, and the volume increased. The lesions appeared as masses with clear borders, present low signals on T1WI in all 8 cases and spot-like high signals in 3 cases, uneven iso-low signals on T2WI showed. Epididymis and spermatic cord involvement were found in 3 cases, the boundary of testis and epididymis were not clear, and signals were heterogeneous, spermatic cord with multiple curved strips of high signal on T2WI. Hydrocele occurred in 3 cases, including 1 case involved epididymis and spermatic cord. Obviously heterogeneous enhancement of lesions was found during delayed enhancement scanning, and unenhanced areas were noticed in 3 cases. The time-intensity curves (TIC) of lesions presented outflow type (type Ⅲ) in all 8 cases. On DWI, the solid parts of lesions showed high signal, which showed low signal on ADC map in all 8 cases. Conclusion MRI manifestations of PTL had certain characteristics. Combination of plain and dynamic enhancement MR were helpful to correct diagnosis of PTL. |
