Abstract Atrial myxomas are rare cardiac tumors. It has to be surgically resected early when diagnosed, due to possible complications such as intracardiac obstruction, embolus, and metastasis. It becomes more challenging when found as an incidental finding in routine evaluation for a case of a ruptured aneurysm. Atrial myxoma is a common cause of ischemic and hemorrhagic strokes, but in 10%–15% of cases, it is associated with the development of metastatic intracranial aneurysms which is a rare complication of myxomatous emboli. We report the case of a 42-year-old female patient presented with subarachnoid hemorrhage, posted for the repair of left paraclinoid internal carotid artery aneurysm under general anesthesia with left interatrial septum myxoma.
