Spontaneous internal carotid artery dissection occurs in patients of all ages, rarely presenting with hypoglossal nerve palsy. The characteristic imaging findings of internal carotid artery dissection and tongue denervation are reviewed in four patients. Recognition of internal carotid artery dissection is critical for appropriate treatment and to minimise the risk of thromboembolic-ischaemic complications. Radiologists must be aware of the radiological appearance of hypoglossal nerve palsy and maintain a high index of suspicion for internal carotid artery dissection when this finding is present.
自发性颈内动脉夹层在各年龄段患者中均有发生，很少表现为舌下神经麻痹。本文回顾了4例颈内动脉夹层和舌神经失支配的典型影像学表现。认识颈内动脉夹层对于恰当治疗及降低血栓栓塞性缺血并发症的风险至关重要。放射科医生必须了解舌下神经麻痹的影像学表现，当出现这一表现时，要对颈内动脉夹层保持高度怀疑。
