Introduction In the complex landscape of vascular neurology, identifying the etiology of an ischemic stroke is paramount for secondary prevention. While carotid stenosis and atrial fibrillation are the usual suspects, the aortic arch remains a critical, often underappreciated source of cerebral emboli. This condition, often referred to as Cerebral Embolism of Probable Aortic Origin , represents a significant diagnostic and therapeutic challenge. Today, we delve into a fascinating case study of a 70-year-old female presenting with a calcified cerebral embolus. We will explore the intricate imaging findings, dissect the pathophysiology of aortic arch atheroma , and review the latest evidence-based guidelines for diagnosis and treatment. This comprehensive guide is designed for medical students, residents, and practicing physicians preparing for board exams or seeking to update their clinical knowledge on cryptogenic stroke and calcified emboli . Case Study: The "Shaggy Aorta" ...
