【摘要】 目的　总结间脑区大范围梗塞的影像学表现。方法　 5例均行MRI平扫 ,2例行MRI增强扫描 ,2例行MRA ,3例行CT平扫与增强检查。诊断经临床过程证实。结果　 5例均为急性起病。CT平扫未显示病变。MRI平扫病变为略长T1与长T2信号。CT与MRI增强扫描均在丘脑与底丘脑核团区域出现结节状强化。 1例复查病变长T2信号与T1增强结节均明显缩小。结论　间脑大范围梗塞少见 ,可能与其血供丰富有关 ,其影像学表现有一定的特征。更多还原

【Abstract】 Objective To study the CT and MR imaging of larger infract of diencephlon. Methods Five patients had non enhnaced MR study, including 2 of them had MR enhanced MR examination and 2 of them had MRA data. Three cases had CT examination data. The diagnosis of all these patients were confirmed by the clinical course. Results All the 5 cases were acute stroke.The diecephlon infract was not detected by non enhanced CT examination and manifested as faint long T1 and long T2 signal on non enhanced MR imaging.The enhanced nodules were found on CT and MR imaging after contrast material injected.On the follow up MR imaging of one case,the area of long T2 as well as enhanced nodule decreased markedly. Conclusion The larger infract of diecephalon is rather rare disease. The cause of its rarity probabely is the rich blood supply of diecephlon. Certain characteristic CT and MR manifestation could be found to the larger infract of diecephalon.更多还原
