Brainstem stroke caused by left atrial cardiac papillary fibroelastoma: an increasingly recognized rare cause of stroke.

Cardiac papillary fibroelastoma is a rare but increasingly recognized cause of embolic stroke that is prevalent in the older population and requires prompt surgical management. We report an unusual case of left atrial appendage cardiac fibroelastoma in a 76-year-old gentleman who presented with left internuclear ophthalmoplegia and ataxia, with corresponding diffusion-weighted imaging on magnetic resonance imaging of the brain. This case illustrates the importance of echocardiographic imaging in the workup of cardioembolic stroke in the older adult population in the acute setting.
