We report the case of a 69-year-old man with a history of mastoidectomy for cholesteatoma, who developed spontaneous spinning vertigo on debridement of his cavity. Subsequent CT confirmed a lateral semicircular canal fistula, which was surgically closed with mastoid cavity obliteration. Following surgery, he developed a spontaneous, pulse-synchronous horizontal pendular nystagmus. We discuss the pathophysiology of this rare clinical sign.
我们报告了一例69岁男性患者，该患者有胆脂瘤乳突切除术史，在清理术腔时出现自发性旋转性眩晕。随后的CT检查证实存在外侧半规管瘘，通过乳突腔闭塞术进行了手术封闭。术后，他出现了自发性、与脉搏同步的水平摆动性眼球震颤。我们讨论了这种罕见临床体征的病理生理学。
