Abstract: The cases of paradoxical brain embolism (PBE) due to venous aneurysms and patent foramen ovale (PFO) are extremely scarce, with only 5 cases caused by popliteal venous aneurysm reported in the literature to date, while PBE caused by deep femoral venous aneurysm (DFVA) and PFO has not been reported. Herein, an unusual case of PBE in a 15-year-old girl with PFO who still had cerebral infarction and pulmonary embolism after transcatheter closure was present. She was finally diagnosed as PFO with DFVA by angiography. Furthermore, clinical characteristics of 6 cases were summarized to improve the clinicians′ recognition of the rare risk factor of stroke-venous aneurysms of the lower extremity deep veins.
