[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.
