“…[3] Our patient also presented with syncope as reported by Treistman et al . [5] Although PAS is a rare tumor, the true prevalence is underestimated as many cases of PAS are misdiagnosed as PTE leading to inappropriate therapy. Both diseases appear as intraluminal filling defects in the pulmonary artery system on contrast-enhanced CT scans and differentiating radiologically between PAS and PTE is relatively difficult.…”

Pulmonary artery sarcoma (PAS), although rare, must be considered in the differential diagnosis of pulmonary thromboembolism (PTE). This tumor is highly malignant and the prognosis is very poor. As much as the standardized uptake values (SUVs) at fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) have helped in differentiating between benign and malignant tumors, visualization of a low-attenuation filling defect within a pulmonary artery on contrast-enhanced chest computed tomography (CT) can be suggestive of a malignancy, such as PAS, if the lesion shows high FDG uptake at PET. We present a case of PAS that showed high FDG uptake on integrated FDG PET/CT and with lung metastasis. Patient underwent endoscopic bronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA), which confirmed spindle cell sarcoma.

“…Progressive obstruction of the pulmonary artery results in RV hypertension, which may ultimately precipitate RV failure, syncope, or sudden death. 5,8 Although right outflow tract obstruction is commonly fixed, a ''toand-from'' movement caused by the contracting heart may result in dynamic obstruction. 9,10 Symptoms typically include dyspnea, cough, chest pain, syncope, and palpitations, and the disease is commonly misdiagnosed as a pulmonary embolism.…”

Purpose To describe a case of acute right ventricular dysfunction and hemodynamic collapse under general anesthesia in a patient undergoing resection of a pulmonary artery sarcoma. Clinical features A 67-yr-old woman with a presumptive diagnosis of pulmonary embolism presented to the hospital with progressive shortness of breath and syncope despite therapeutic anticoagulation. An echocardiogram revealed a large mass in the main pulmonary artery and a right ventricular systolic pressure of 105 mmHg. She was referred to our centre for urgent surgical management.
