Abstract
Myxomas are slowly growing benign neoplasms and represent the most common tumor of the heart. Embolism from cardiac myxoma occurs in 30-45% of patients and in at least half of the cases cerebral arteries are affected leading mainly to embolic ischemic strokes and rarely to delayed intracranial aneurysm formation. We present two cases with delayed intracranial aneurysmal formation 14 years and 18 years after cardiac myxoma resection. To the best of our knowledge these two cases represent the longest time interval between aneurysm detection after complete cardiac myxoma resection with no recurrence confirmed by transesophageal echocardiogram. Our study also provides the longest clinical and radiological follow-up on this type of lesion.
