摘要
目的:探讨CT及MRI对儿童下丘脑错构瘤的诊断价值。方法:回顾性分析结手术病理证实的5例下丘脑错构瘤患儿的CT及MRI表现。结果:全部病例均表现为病变位于垂体柄与乳头体之间,病灶与灰结节、乳头体相连。3例在CT上呈均匀等密度,5例在T1WI上呈等脑灰质信号,T2WI呈稍高信号,信号均匀,所有病变在增强CT及MRI上均无明显强化。结论:儿童下丘脑错构瘤具有典型的CT及MRI表现,结合临床资料可明确诊断。
Objective：To study the value of CT and MRI in the diagnosis of hypothalamie hamartoma in children. Methods：The CT and MR1 materials of five pediatric patients with surgery and pathology proven hypothalamic hamartoma were retrospectively analyzed. Results： All cases showed the location of nodular lesion in between pituitary stalk and mammillary body, connecting with tuber cinereum and mammillary body. 3 cases appeared as homogeneous lso-attenuation on CT images;5 cases appeared to be homogeneously iso-intense with gray matter on T1 weighted images and slightly hyper-intense on T2 weighted images. All lesions showed no obvious enhancement on CT and MRI. Conclusion： The CT and MRI manifestations of hypothalamie hamartoma in children are characteristic, definite diagnosis can be obtained by imaging examination in combination with clinical data.
