Papillary fibroelastomas are rare and benign cardiac tumors that typically
affect the cardiac valves. To the best of our knowledge, the English litera
ture contains only 1 case report of pulmonary valve fibroelastoma diagnosed
by echocardiogram and confirmed by surgical resection. There is a paucity
of pathology literature on this subject. We describe an additional case of
pulmonary valve fibroelastoma diagnosed by transesophageal echocardiography
and magnetic resonance imaging confirmed by pathologic examination in a pa
tient who also had a thymoma.
