Harlequin syndrome in a patient with putative autoimmune autonomic ganglionopathy

The author presents a patient with Harlequin's and Horner's syndrome as part of an autoimmune autonomic ganglionopathy and suggests implication for work-up and management. In general, Harlequin's and Horner's syndromes are reported to be caused by either a structural lesion of the sympathetic pathway or, when no structural lesion is found, are presumed to be idiopathic. In this paper, a 76year old man developed a Harlequin's and Horner's syndrome in the setting of subacute autonomic failure and other systemic features.
