title: Ischemic stroke due to paradoxical embolism arising from a popliteal vein aneurysm.
abstract: Popliteal vein aneurysm (PVA) is a very uncommon cause of stroke. We present the case of a 63-year-old, right-handed man who presented to the emergency department with transitory ischemic accident (left superior extremity regressive monoplegia). Complete etiologic work-up led to the discovery of both a patent foramen ovale associated with an septum interauricular aneurysm, and of a PVA without mural thrombus. The diagnosis of brain paradoxical embolism was retained. The unique potentially embolic cause was the presence of the PVA. We decided to treat the PVA surgically to avoid a further cerebral vascular episode. Although uncommon, venous etiology must be considered for stroke.
