To demonstrate the importance of thorough investigation of patients with Horner syndrome, and to explain the relevant anatomy.
A 46-year-old man presented with right-sided Horner syndrome. No other abnormality was found. Magnetic resonance imaging showed calcification of the stylohyoid ligament, with a pseudoarthrosis in the mid-portion of the ligament. This pseudoarthrosis was displacing and compressing the internal carotid artery and the adjacent sympathetic chain, causing Horner syndrome.
In this case, magnetic resonance imaging was invaluable in elucidating the cause of the Horner syndrome. This is the first described case of pseudoarthrosis of a calcified stylohyoid ligament causing Horner syndrome.
证明对霍纳综合征患者进行全面检查的重要性，并解释相关解剖结构。
一名46岁男性出现右侧霍纳综合征。未发现其他异常。磁共振成像显示茎突舌骨韧带钙化，韧带中部存在假关节。该假关节移位并压迫颈内动脉和相邻的交感神经链，导致霍纳综合征。
在本病例中，磁共振成像对阐明霍纳综合征的病因非常有价值。这是首例关于钙化茎突舌骨韧带假关节导致霍纳综合征的病例报道。
