title: Isolated Cortical Vein Thrombosis with Long Cord Sign.
abstract: 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.
