摘　　要：1例19岁男性患者,反复发作性言语不利伴右侧肢体麻木无力,每次发作持续10~40 min,神经系统体格检查无阳性体征。头部MRI示脑实质未见明确损害,头颈部CT血管成像未见明显异常,视频动态脑电图正常,头部增强MR静脉成像(MRV)示上矢状窦、右侧横窦、乙状窦血栓形成可能。诊断脑静脉窦血栓形成(CVT)导致的短暂性脑缺血发作(TIA),利伐沙班抗凝治疗后,患者未再出现TIA症状。以TIA起病的CVT罕见,TIA原因不明时,需完善头部MRV以免误漏诊。We reported a 19-year-old male patient presented with recurrent dysphasia accompanied with right limb numbness and weakness.Each episode lasted 10-20 minutes.Neurological signs were not found during physical examination.No obvious parenchyma lesions were found in brain MRI.Both CTA and video electroencephalography were normal.Contrast-enhanced MR venography(MRV)showed possible cerebral venous sinus thrombosis in superior sagittal sinus,right transverse sinus and sigmoid sinus.Thus,transient ischemic attack(TIA)caused by cerebral venous thrombosis(CVT)was diagnosed.The patient had no recurrent attacks after rivaroxaban anticoagulation therapy.CVT with initial symptom of TIA is quite rare.When the cause of TIA is unknown,cranial MRV should be conducted to avoid misdiagnosis and missed diagnosis.
