Pulmonary Artery Fibroelastoma Excision in a 67-Year-Old Female Patient Presented With a Chronic Cough.

BACKGROUND: Papillary fibroelastoma is a rare, benign cardiac tumor, most commonly found on left-sided heart valves. Right-sided involvement, particularly the pulmonary valve, is exceedingly rare but carries a high embolic risk. CASE SUMMARY: A 67-year-old woman presented with chronic cough and dyspnea. Imaging revealed a mobile pulmonary valve mass, initially suspected as vegetation. Further evaluation with echocardiography and magnetic resonance imaging suggested fibroelastoma. Due to diagnostic challenge and high embolic risk, a diagnostic surgical excision was planned. DISCUSSION: This case highlights diagnostic challenges and reinforces the importance of considering cardiac tumors in atypical presentations.
