[Cerebral embolism as an atypical presentation of May Thurner syndrome]

May-Thurner syndrome is an anatomic abnormality that predisposes patients to increase risk of paradoxical embolism and stroke. It consists of chronic compression of the left common iliac vein by the overlying right common iliac artery and lumbar spine. This may lead to deep venous thrombosis and paradoxical embolism that could provoke cerebral ischemia in patients with a cardiac shunt from right-to-left. Embolic cerebral ischemic event is reported in a 30-year-old man after sexual intercourse. Further studies revea led suggestive findings of May-Thurner syndrome coupled with a patent foramen ovale and a factor V Leiden thrombophilia. He was placed on anticoagulation therapy and has not had any recurrent events.
