Pulmonary Artery Sarcoma Mimicking Chronic Pulmonary Thromboembolism: A Case Report

模仿肺栓塞之肺動脈肉瘤-病例報告

摘要


肺動脈肉瘤是造成肺動脈阻塞的極罕見病因。由於其臨床表徵及影像學特徵與肺栓塞極為相似,肺動脈肉瘤常被誤診為肺栓塞,真實發生率也因此而被低估。我們在此報導了一個最初被診斷為肺栓塞而之後確診為肺動脈肉瘤的病例。我們也從文獻中回顧此兩種疾病在臨床與影像學上可供辨識之特徵。

並列摘要


Pulmonary artery sarcoma is an extremely rare cause of pulmonary artery obstruction. Because of its similarity in clinical presentations and radiographic findings to pulmonary thromboembolism, the tumors are frequently misdiagnosed and its true incidence is probably underestimated. Herein, we describe a patient with a presumptive diagnosis of chronic pulmonary thromboembolism who was later found to have pulmonary artery sarcoma. We also review the distinguishing clinical and radiographic characteristics of the 2 diseases.
