Here we report a 60 years old man without any previous medical condition who presented with non-specific symptoms and underwent different investigations for more than 1 year, until the presence of a continuous murmur raised suspicion toward his cardiovascular system. In echocardiographic and computed tomography (CT) angiographic studies a large pseudoaneurysm of aortic arch with compression effect on pulmonary artery was detected. At this stage he remembered having suffered a minor trauma 10 years ago. He finally underwent operation and his aortic wall was repaired successfully with a patch. This case highlights the importance of thorough history taking and physical examination in patients irrespective of symptoms and high index of suspicion to detect this life-threatening condition.
