目的分析原发性颞下窝肿瘤的MRI表现和临床病理特点,评价MRI对原发性颞下窝肿瘤的诊断价值.方法回顾性分析28例经病理证实的原发性颞下窝肿瘤MRI表现与病理学资料,将MRI表现与肿瘤的良恶性生物学行为进行对比研究.结果①28例原发性颞下窝肿瘤良性肿瘤8例,恶性肿瘤20例;发生于左侧颞下窝15例,右侧颞下窝13例;②良恶性肿瘤临床症状及体征大多不具有特征性.③原发性颞下窝肿瘤中良性肿瘤平均直径为43.2 mm,恶性肿瘤平均直径为65.6 mm,两者差异具有统计学意义;④良性肿瘤MRI主要表现为:形态规则,边界清晰,几乎不引起周围结构的侵蚀、破坏,增强扫描后大多数呈轻~中度均匀强化;恶性肿瘤MRI主要表现为:形态不规则,边界不清,不同程度的引起周围结构的侵蚀、破坏,增强扫描后呈明显不均匀强化.结论MRI能准确的评价颞下窝肿瘤的边界范围,及对周围结构的侵蚀,很好的鉴别肿瘤的良恶性,并进一步诊断其病理类型,为颞下窝肿瘤病变的临床诊治及疗效评估提供重要信息.

Objective To determine the relationship between MRI appearance and pathological features of primary infratemporal tumors.Methods MRI of 28 patients with histologically confirmed primary infratemporal tumors was compared with the pathological findings.Results Of 28 primary infratemporal tumors,8 were benign and 20 were malignant,15 were on the left and 13 were on the right.The clinical features were similar for both benign and malignant tumors.The mean diameter of benign tumor and malignant tumors were 43.2 mm and 65.5 mm,respectively.The benign tumors had regular shapes,clear borders,no invasion of adjacent structures,and mild-to-moderate contrast enhancement on MRI.Malignant tumors were irregular in shape with poorly-defined boundary,invading adjacent structures,and heterogeneous contrast enhancement.Conclusions MRI is valuable in demonstrating infratemporal tumors and differentiating malignant from benign tumors.
