Abstract
A 24-year-old woman presented with a seizure-like episode of left hemibody sensory loss. Magnetic resonance imaging and magnetic resonance angiography revealed multiple distal fusiform cerebral aneurysms requiring angiographic evaluation and possible endovascular treatment. On preoperative workup, transthoracic echocardiography revealed a large, 4.1× 2.1 cm, mobile left atrial mass prolapsing into the left ventricle during diastole. Multidisciplinary discussion among representatives from neurosurgery, cardiology, and cardiothoracic surgery determined the plan to proceed with diagnostic cerebral angiogram and aneurysm embolization before moving forward with heart surgery. Cerebral angiogram revealed several right distal middle cerebral artery fusiform aneurysms and a right distal posterior inferior cerebellar artery fusiform aneurysm. Subsequently, the patient underwent endovascular coil embolization of the largest distal M4 fusiform aneurysm, measuring 3.3× 3.2 mm in maximal diameter. The patient recovered to baseline in the surgical intensive care unit and was discharged home on postoperative day 7 with close neurosurgical and cardiology follow-up.
