【摘要】：目的探討丘腦靜脈性梗死的臨床和影像學(xué)表現(xiàn),以提高對該病的認(rèn)識。方法 8例經(jīng)臨床證實(shí)為靜脈竇血栓引起的丘腦靜脈性梗死,收集其臨床及影像學(xué)資料并進(jìn)行回顧性分析。結(jié)果 8例患者均進(jìn)行MRI平掃、DWI和SWI檢查,均經(jīng)DSA確診。5例雙側(cè)丘腦、基底節(jié)區(qū)長T_1長T_2信號;1例雙側(cè)丘腦長T_1長T_2信號,伴胼胝體膝部短T_1信號;1例雙側(cè)丘腦、基底節(jié)區(qū)長T_1長T_2信號,伴右側(cè)丘腦短T_1信號;1例雙側(cè)丘腦稍長T_1稍長T_2信號,并累及右側(cè)基底節(jié)區(qū)和中腦,DWI呈高信號,ADC呈稍低信號。1例胼胝體膝部、1例右側(cè)丘腦SWI圖像上為低信號出血,2例梗死區(qū)內(nèi)灶狀出血。MRV與DSA檢查結(jié)果相一致,5例為雙側(cè)橫竇、上矢狀竇、直竇、竇匯血栓形成;1例為雙側(cè)橫竇、上矢狀竇、直竇、大腦大靜脈血栓形成;1例為右側(cè)橫竇、乙狀竇血栓形成;1例為右側(cè)橫竇、直竇血栓形成。結(jié)論臨床上遇到雙側(cè)丘腦病變,要考慮靜脈性梗死的可能。MRI平掃聯(lián)合MRV是靜脈竇血栓引起的丘腦靜脈性梗死診斷及隨訪的首選檢查方法。SWI可清晰顯示微出血,是MRI平掃和MRV極好的補(bǔ)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.
