摘　　要：目的:探讨下视丘胶质瘤的临床及MRI表现,提高对此病的认识。方法:回顾性分析5例经手术病理证实的下视丘胶质瘤患者的影像及临床资料。结果:MRI平扫,病变多位于鞍上,呈分叶状肿块,T1WI上多表现为低信号或等低混杂信号,T2WI上大多表现为高或等高混杂信号。增强扫描,肿瘤可见明显或轻度不均匀强化。结论:下视丘胶质瘤的影像及临床表现有一定的特点,MR检查对诊断有重要帮助。Objective.. To explore the clinical and MRI features of optic-hypothalamic gliomas and to improve the understanding of this disease. Methods：The imaging findings and the clinical data of 5 patients with pathologically proved optic-hypothalamic gliomas were retrospectively analyzed. Results.. The lesion presented a suprasella lobulated mass, being hypointense or isointense signal on T1 WI and hyperintense or heterogeneous signal on T2WI. Most part of the lesion showed heterogeneous enhancement on the MRI. Conclusion：Optic-hypothalamic gliomas carry certain MRI features, which play an important role in the diagnosis of this disease.
