目的:探讨静脉脑栓塞患者的发病原因、临床表现及CT、磁共振成像(MRI)的影像表现。方法:回顾性分析8例(12处病灶)经临床及影像学联合检查确诊的静脉性脑栓塞患者临床资料。其中6例接受MRI增强扫描,部分患者接受外科手术治疗。分析其治疗前后CT平扫及MRI序列检查结果,评估其影像表现。结果:8例确诊患者中浅表型静脉性栓塞6例(单侧5例、双侧1例),临床表现为头痛、恶心、呕吐、局灶性神经功能缺损或癫痫发作;深部中央型静脉性栓塞者2例(单侧/双侧基底节丘脑静脉梗死各1例),临床表现均较轻且病情进展缓慢,预后效果较理想。12处病灶CT平扫均呈低密度影;T1WI图像呈低信号,DWI图像则呈高信号,T2WI图像呈高信号9处,混杂信号3处;6例行MRI增强扫8处病灶强化环厚薄均匀,但形态欠规则。结论:MRI相较于CT检查,能帮助医师更直观、清晰地了解静脉脑栓塞患者的病灶信息,对针对性治疗方案的拟定和预后效果的准确评估具有积极影响。
Objective: To investigate the etiology, clinical manifestations and imaging manifestations of CT and magnetic resonance imaging (MRI) in patients with venous thrombosis. Methods: The clinical data of 8 patients (12 lesions) with venous thromboembolism diagnosed by clinical and radiographic examination were retrospectively analyzed. Six patients underwent MRI scans and some received surgical intervention. Before and after treatment of CT scan and MRI sequence examination results to assess the imaging performance. Results: Six cases of superficial venous embolism were diagnosed in 8 cases (5 in unilateral and 1 in bilateral). The clinical manifestations were headache, nausea, vomiting, focal neurological deficit or seizure. The deep central venous 2 cases of embolism (unilateral / bilateral basal ganglia thalamic infarction in 1 case), the clinical manifestations were mild and the disease progressed slowly, the prognosis is better. CT lesion in 12 lesions showed low density, T1WI image was low signal, DWI image was high signal, T2WI image was high signal 9, mixed signal 3; 6 cases enhanced MRI scan 8 lesions enhanced ring thickness Even, but the shape of the rules. Conclusion: Compared with CT scan, MRI can help physicians understand more clearly and clearly the information of focal lesion in patients with venous thromboembolism, and has a positive effect on the formulation of targeted therapy and accurate assessment of prognosis.
