摘要
目的探讨睾丸良性病变MRI的表现及诊断价值。方法回顾性分析12例经病理证实的睾丸良性病变患者的MRI平扫及增强扫描的影像资料。结果 12例患者中,良性畸胎瘤2例,表皮样囊肿2例,leydig细胞瘤3例,肉芽肿性炎症3例,结核2例。MRI对睾丸病变定位准确,大多数病变具有一定特征性,良性畸胎瘤可含有脂肪组织或钙化灶,表皮样囊肿有包膜存在,炎症和结核鉴别主要依靠阴囊隔是否有侵犯,leydig细胞瘤无明显特征,容易误诊。结论运用MRI仔细观察睾丸良性病变的形态特征、信号、强化程度及周围情况,有利于病变的定位,有助于病变的诊断与鉴别诊断。
Objective To evaluate the magnetic resonance imaging （MRI） appearances and diagnostic value of the benign lesions in testis. Methods The data of plain and contrast MRI of benign lesions in testis of 12 patients was retrospectively analyzed. Results Of the 12 patients, benign teratoma was found in 2 patients, epidermoid cyst in 2 patients, leydig cell tumor in 3 patients, nonspecific inflammatory mass in 3 patients, and tuberculosis in 2 pa- tients. MR/could display and locate the testicular lesion accurately, most of which had characteristic imaging appear- ances on MRL Benign teratoma showed adipose tissue or calcification stove, and cpidermoid cyst had envelope. The differential identification of inflammation and tuberculosis relied mainly on the isolation of the scrotum infringed or not. Leydig cell tumor showed no obvious characteristics and could be easily misdiagnosed. Conclusion Observing carefully the morphological characteristics, signal, enhancement and situation of the benign lesions in testis with MRI is helpful for the diagnosis, differential diagnosis, and location of the lesion.
