High-altitude Pulmonary Edema with Pulmonary Thromboembolism

High-altitude pulmonary edema (HAPE) is a form of noncardiogenic pulmonary edema. The pathophysiology of HAPE remains unclear. A case of HAPE was associated with pulmonary thromboembolism of a left upper pulmonary artery. Pulmonary thromboembolism was an important factor in development of HAPE in this case.
