Reentrance of Azygos Vein into Azygos Fissure After Pneumothorax

Eurasian J Med. 2017 Feb;49(1):62-63. doi: 10.5152/eurasianjmed.2017.16267.

Abstract

Empty azygos fissure implies dislocation of the azygos vein to the mediastinal side of the right upper lobe from azygos fissure, which is usually secondary to pneumothorax, pleural effusion, parenchymal fibrosis, vertebral collapse or persistent vomiting. We are presenting here a case where a separated azygos vein in CT and radiography images was noted. Moreover, in the follow-up images, it appeared that the complete reexpansion of the right lung resulted in reentrance of the azygos vein into azygos fissure in its native position.

Boş azigos fissürü, azigos veninin pnömotoraks, plevral efüzyon, parankimal fibrozis, vertebral çökme ve persistan kusma gibi nedenlerle azigos fissüründen sağ üst lobun mediastinal tarafına doğru yer değiştirmesini ifade eder. Bu olgu sunumunda BT ve radyografilerde ayrılmış azigos veni bulunan ancak takip görüntülemelerde sağ akciğerdeki reekspansiyona bağlı azigos veninin azigos fissürü içine tekrar girdiği saptanan bir olgu sunulmuştur.

Keywords: Azygos vein; anatomic variation; multislice computed tomography; pneumothorax.
