Stroke is a second cause of mortality worldwide and a leading cause of acquired disability in adults. Approximately 20% of all ischaemic strokes are of cardioembolic origin. We present a case of a 60-year-old man with a history of stroke without changes in carotid and vertebral arteries. Echocardiography exam revealed patent foramen ovale (PFO) and abnormal echos in the aorta that were verified as advanced complex atheromas by computed tomography. Due to small size PFO was deemed insignificant and the source of embolism were most probably aortic atheromas. Patient was put on acenocumarol, aspirin and statin.
