A patent foramen ovale (PFO) is a common heart defect in the general population. Paradoxical embolization of material through a PFO has been an identified cause of stroke. Taking measures to recognize a PFO in a patient undergoing intra-arterial particulate embolization is necessary in order to reduce the risk of stroke secondary to paradoxical embolism. We present a case of paradoxical stroke in a patient with a highly vascular head and neck tumor and an asymptomatic PFO.
