Insights
A rare cardiac tumor, papillary fibroelastoma, caused a stroke in a 75-year-old man. Surgical removal of the left atrial mass led to a full recovery with no recurrence.
Area of Science:
- Cardiology
- Neurology
- Pathology
Background:
- Cerebral infarction can result from cardiogenic embolism.
- Cardiac tumors are an uncommon cause of embolic stroke.
Observation:
- A 75-year-old male presented with parietal lobe cerebral infarction.
- Imaging revealed a mobile, speckled mass in the left atrium.
- The mass's appearance on imaging suggested a cardiac source.
Findings:
- Surgical resection of the left atrial mass was performed.
- Pathological examination confirmed the mass as a papillary fibroelastoma.
- The tumor consisted of fibroelastic tissue with a single endocardial layer.
Implications:
- Papillary fibroelastomas, though rare, should be considered in cases of embolic stroke.
- Surgical excision is an effective treatment for cardiac tumors causing embolism.
- Complete resection of papillary fibroelastoma can lead to favorable long-term outcomes.
Abstract:
A 75-year-old man was admitted for cerebral infarction. Magnetic resonance imaging revealed parietal lobe cerebral infarction. Transesophageal echo and contrast-enhanced computed tomography indicated mobile and speckled mass arising from left atrium. He was diagnosed with cardiogenic cerebral embolism. Under cardiopulmonary bypass, resection of the mass including endocardium tissue was per formed. The resected specimen showed multiple small fronds resembling a sea anemone. Microscopic examination showed multiple branching fronds of paucicellular and avascular fibroelastic tissue lined by a single layer of endocardium. Pathological diagnosis was papillary fibroelastoma. Three years passed without recurrence.
