A patient is described in whom clinical presentation, V/Q scan, and pulmonary angiogram were consistent with pulmonary embolus. No improvement occurred despite therapy with heparin. When sent for surgical embolectomy, sarcoma of the pulmonary artery was diagnosed. This entity, though rare, should be considered in the differential diagnosis of pulmonary vascular disease.

A 21-year-old male patient with massive acute pulmonary embolism was treated by thrombolysis, interventional thrombus fragmentation, and surgical pulmonary embolectomy. Within the following 2 years, the patient developed progressive dyspnea at exertion. Chronic thromboembolic pulmonary hypertension was diagnosed by right-heart catheter, VQ scan, magnetic resonance, and conventional pulmonary an...

A 44 year old patient with end stage idiopathic pulmonary fibrosis underwent single left lung transplantation. A perfusion lung scan performed 13 days after transplantation revealed deficient perfusion in the transplanted lung. Pulmonary angiography showed severe pulmonary artery anastomotic stenosis. Percutaneous insertion of a balloon expandable stent improved both pulmonary perfusion and res...

UNLABELLED INTRODUCTION When a pulmonary nodular lesion is detected by F-18 fluorodeoxyglucose positron emission tomography-computed tomography in a patient with post-surgical papillary thyroid carcinoma with undetectable serum-stimulated thyroglobulin levels and negative 131I whole body scan, diagnosis and management of the nodule may be confusing. CASE PRESENTATION We describe two post-s...

Plasma concentrations of cross linked fibrin degradation products, a marker of intravascular thrombosis and fibrinolysis, were measured in 495 patients with suspected pulmonary embolism referred for ventilation-perfusion lung scanning to determine whether concentrations are increased in pulmonary embolism and their potential use in diagnosis. Lung scans were described as normal (n = 66) or as s...
