Pulmonary Artery Sarcoma Mimicking Massive Pulmonary Embolus: A Case Report

Abstract

Intimal sarcomas of the pulmonary artery are rare tumors that are often difficult to distinguish from pulmonary thromboembolic disease, complicating accurate diagnosis and timely therapy. We report the case of a gentleman with a primary pulmonary artery sarcoma who presented with a massive pulmonary embolism and complete right ventricular outflow tract obstruction. The patient's condition was successfully managed with urgent pulmonary artery thromboendarterectomy, pulmonary valve replacement, and tricuspid valve annuloplasty.
