A Rare Pulmonary Artery Sarcoma Masquerading as Pulmonary Embolus.

We present the case of a 46-year-old woman with a presumed diagnosis of multiple unprovoked pulmonary emboli. Her cardiorespiratory function continued to deteriorate despite optimal medical therapy. At surgical thrombectomy she was identified to have an intimal soft tissue lesion arising from the right pulmonary artery.
