摘　　要：目的分析灰结节错构瘤的MRI特点及诊断价值。方法回顾性分析经手术病理证实4例灰结节错构瘤的MRI表现,所有病例均行横轴位、冠状位、矢状位三维的MR平扫及增强扫描。结果4例灰结节错构瘤病例MRI都表现为鞍上灰结节处肿块,T1WI和T2WI为等信号,增强扫描病灶无强化。MRI能清晰显示肿瘤的位置及其与邻近解剖结构的关系。结论灰结节错构瘤有特征性的MRI表现,MR可作为一种常规的影像学检查方法对灰结节错构瘤患者进行诊断和追踪。Objective To analyze the MRI findings of tuber cinereum hamartoma and to determine the value of MRI for diagnosing this disease. Methods Four patints with surgically and pathologically proved tuber cinereum hamartoma underwent MR imaning in the axial, sagittal and coronal plane before and after venous bolus injection of Gd-DTPA. The MR findings of tuber cinereum hamartoma in all patients were analyzed retrospectively. Results MRI findings of tuber cinereum hamartoma in all patients were suprasellar masses. All the lesions were isointense on T1 and T2 weighted images and were non-enhanced after enhancement scans. MR imaging could clearly reveal the locations of tumoral lesions and their relation to neighbor anatomic structures. Conclusion MRi findings of tuber cinereum hamartoma have certain feature so that MR imaging can be taken as a routine method for diagnosing and following -up this disease.
