We present a 60-year-old man with a complete right IX-XII nerve palsy (Collet-Sicard syndrome) due to spontaneous right internal carotid artery (ICA) dissection. Magnetic resonance imaging (MRI) and MR angiography (MRA) showed signs of subadventitial dissection of the right ICA with a mural haematoma that expanded the circumference of the vessel at the level of the retrostyloid space, adjacent to the IX-XII nerves. No narrowing of the lumen or aneurysms was found. Clinical recovery was excellent after treatment with only antiplatelet drugs. Cervical internal carotid artery dissection should be included in the differential diagnosis of lower cranial nerve palsies. MRI and MRA are noninvasive, reliable methods for diagnosis and follow-up, especially in subadventitial dissections.
我们报告一名60岁男性，因自发性右颈内动脉（ICA）夹层形成导致完全性右侧IX - XII神经麻痹（科莱-西卡尔综合征）。磁共振成像（MRI）和磁共振血管造影（MRA）显示右ICA外膜下夹层的征象，伴有壁内血肿，该血肿在茎突后间隙水平使血管周长增大，邻近IX - XII神经。未发现管腔狭窄或动脉瘤。仅用抗血小板药物治疗后临床恢复良好。颈内动脉夹层应纳入低位颅神经麻痹的鉴别诊断。MRI和MRA是无创、可靠的诊断和随访方法，尤其适用于外膜下夹层。
