Harlequin syndrome is a rare syndrome characterized by hemifacial flushing and altered facial sweating, with only a few case reports related to intercostal blockades. We present a case of Harlequin syndrome in a 65-year-old woman after intercostal blockade for video-assisted thoracoscopic lobectomy. One hour postoperatively, the patient became nauseated and presented with flushing of the right half of the face with a clear line of demarcation. Within 3 hours, the flushing disappeared. In this case report, we discuss Harlequin syndrome in relation to intercostal blockade and encourage clinicians to consider this syndrome in the differential diagnosis when encountering similar symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
