An Unusual Cause of Large Thrombosed Pulmonary Artery Aneurysms Associated with Chronic Thromboembolism

慢性肺栓塞引發的罕見肺動脈瘤併血栓性栓塞症-病例報告

摘要


由於影像學的進步,用電腦斷層診斷肺動脈栓塞已是廣為接受的檢查。本文報告一個罕見病例,因慢性肺栓塞而引發的單側多發性肺動脈瘤並合併血栓性栓塞症。胸部X光素片顯示在右側肺門區域有許多圓形的白點病灶。胸部電腦斷層顯示明顯的動脈瘤分布在右側肺動脈的主要分支,並且內含有大血栓。在過去的文獻裡,這種型態的肺動脈瘤並未描述過。

並列摘要


We present a rare case of unilateral multiple large thrombosed pulmonary artery aneurysms that occurred in the course of chronic pulmonary thromboembolism in a 51-year-old man. Chest radiography showed multiple rounded opacities in the right hilar and parahilar regions. CT scans showed marked aneurysmal dilatation of the segmental and lobar branches of the right pulmonary artery containing large thrombi. This pattern of pulmonary artery aneurysms has not been previously reported.
