title: MRI finding of a papillary muscle cyst: a differential diagnosis.
abstract: Cystic lesions of the papillary muscle in the form of myxoma, hydatid cyst, papillary fibroelastoma, blood-filled cysts and endodermal heterotopia are rare causes of embolic stroke. In view of the potential complications caused by these lesions, surgery is often advocated but there is no consensus on which patients qualify. We examined a differential diagnosis of a papillary muscle cystic lesion in a patient presenting with features of embolic disease and identified the imaging features on MRI that directed management.
