【摘要】:目的探讨丘脑静脉性梗死的临床和影像学表现,以提高对该病的认识。方法 8例经临床证实为静脉窦血栓引起的丘脑静脉性梗死,收集其临床及影像学资料并进行回顾性分析。结果 8例患者均进行MRI平扫、DWI和SWI检查,均经DSA确诊。5例双侧丘脑、基底节区长T_1长T_2信号;1例双侧丘脑长T_1长T_2信号,伴胼胝体膝部短T_1信号;1例双侧丘脑、基底节区长T_1长T_2信号,伴右侧丘脑短T_1信号;1例双侧丘脑稍长T_1稍长T_2信号,并累及右侧基底节区和中脑,DWI呈高信号,ADC呈稍低信号。1例胼胝体膝部、1例右侧丘脑SWI图像上为低信号出血,2例梗死区内灶状出血。MRV与DSA检查结果相一致,5例为双侧横窦、上矢状窦、直窦、窦汇血栓形成;1例为双侧横窦、上矢状窦、直窦、大脑大静脉血栓形成;1例为右侧横窦、乙状窦血栓形成;1例为右侧横窦、直窦血栓形成。结论临床上遇到双侧丘脑病变,要考虑静脉性梗死的可能。MRI平扫联合MRV是静脉窦血栓引起的丘脑静脉性梗死诊断及随访的首选检查方法。SWI可清晰显示微出血,是MRI平扫和MRV极好的补充。
[Abstract]:Objective to investigate the clinical and imaging manifestations of thalamic venous infarction in order to improve the understanding of the disease. Methods 8 cases of thalamic venous infarction caused by venous sinus thrombosis were studied. Results the clinical and imaging data were collected and analyzed retrospectively. Results all of the 8 patients were examined by MRI plain scan DWI and SWI. All of them were diagnosed by DSA in 5 cases of bilateral thalamus and 1 case of bilateral thalamus with long T 1 T 2 signal in basal ganglia and 1 case with bilateral thalamus long T 1 long T 2 signal, and 1 case with bilateral thalamus long T 1 long T 2 signal, and 1 case with bilateral thalamus long T 1 long T 2 signal. With short T _ 1 signal in the genu of corpus callosum, 1 case with bilateral thalamus, 1 case with long T _ 1 T _ 2 signal in basal ganglia, and 1 case with right thalamus short T _ 1 signal, and 1 case with bilateral thalamus slightly longer T _ 1 and longer T _ 2 signal. The right basal ganglia and midbrain were involved in the right basal ganglia and mesencephalon with high signal intensity. 1 case of corpus callosum genu showed hypointensity hemorrhage on SWI image of right thalamus and 2 cases of focal hemorrhage in infarct area. MRV was consistent with the results of DSA. 5 cases were bilateral transverse sinus. The thrombosis of superior sagittal sinus, straight sinus and confluence of sinus were bilateral transverse sinus, superior sagittal sinus, straight sinus, cerebral vein thrombosis in 1 case, right transverse sinus in 1 case, right transverse sinus in 1 case. Conclusion when we encounter bilateral thalamic lesions in clinic, we should consider the possibility of venous infarction. MRI combined with MRV is the first choice for diagnosis and follow-up of thalamic venous infarction caused by venous sinus thrombosis. It is an excellent complement to MRI scan and MRV.
