The authors report the case of a 24-year-old woman with paradoxical embolism of the right arm subsequent to childbirth. Patent foramen ovale was diagnosed by right cardiac catheterization and contrast echocardiography. On the basis of clinical, immunoscintigraphic and radiologic data, the pelvic region was the only possible origin of the embolic process. The main interest of this case is that arterial ischemic signs were indicative of an embolic process of pelvic origin diagnosed by scintigraphy using radiolabeled antifibrin antibody.
