Isolated cortical vein thrombosis (ICVT) is a rare disease, accounting for less than 1% of strokes. A 46-year-old woman presented with progressive left side weakness. Magnetic resonance (MR) imaging with T2()-gradient echo (T2()-GE) sequence showed long cord sign at the right frontal cortex. The patient was treated with low molecular weight heparin, followed by oral warfarin for 6 months. The 3-month follow-up MR imaging showed recanalization of the previously thrombosed cortical vein. She was completely recovered without neurological deficits after 6 months. This provides that MR imaging with T2(*)-GE sequence can help to diagnosis the ICVT and outcomes of the ICVT are generally favorable.
孤立性皮质静脉血栓形成（ICVT）是一种罕见疾病，占中风的比例不到1%。一名46岁女性出现进行性左侧肢体无力。采用T2（）梯度回波（T2（）-GE）序列的磁共振（MR）成像显示右侧额叶皮质呈长索状征。该患者接受了低分子量肝素治疗，随后口服华法林6个月。3个月的随访MR成像显示先前血栓形成的皮质静脉再通。6个月后她完全康复，无神经功能缺损。这表明采用T2（*）-GE序列的MR成像有助于诊断ICVT，且ICVT的预后通常良好。
