Guillain-Barré syndrome (GBS) is characterized as an acute, symmetrically progressive, inflammatory demyelinating polyneuropathy. We report a case of GBS in which gadolinium-enhanced magnetic resonance (MR) imaging showed marked enhancement of nerve roots of the conus medullaris and cauda equina. On enhanced MR imaging, the spinal cord and nerve roots in the thecal sac generally do not take up much gadolinium because of the blood-nerve barrier or blood-brain barrier. Therefore, in our case, marked enhancement of nerve roots indicates a breakdown of the blood-nerve barrier. It is thought to correlate with the inflammatory infiltration of GBS.
吉兰-巴雷综合征（GBS）的特征是一种急性、对称性进行性炎症性脱髓鞘性多发性神经病。我们报告一例GBS病例，其中钆增强磁共振（MR）成像显示圆锥和马尾神经根明显强化。在增强MR成像上，由于血-神经屏障或血-脑屏障，脊髓和硬膜囊内的神经根通常不会摄取太多钆。因此，在我们的病例中，神经根的明显强化表明血-神经屏障的破坏。这被认为与GBS的炎症浸润相关。
