The azygos vein may be abnormally situated due to anomalous embryologic development. Its abnormal location is infrequent, but radiologic recognition is much easier than that of the normal vein. This vein, normal or abnormal, becomes distended in conditions with an elevated venous pressure, systemic or portal. Changes in the size of the azygos vein on x-ray are noted to parallel fluctuations of ...

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 app...

The adult pattern of the azygos vein system of various mammals has received the attention of many early investigators (Eustachius, 1561 ; Bardeleben, 1848 ; Marshall, 1850; and Morrison, 1879). Since there has not almways been agreement among these workers in the patterns described, attempts were made by some of them to try to correlate the patterns on a developmental basis (Barcleleben, 1848 ;...
متن کاملMigrating azygos vein and vanishing azygos lobe: MDCT findings.
OBJECTIVE The purpose of this study was to describe six cases of migrating azygos vein and to explain the etiologic factors that contribute to the migration. Six patients with migrating azygos vein were studied by MDCT before and after migration. Five patients had right pneumothorax. All patients had repeated episodes of cough, vomiting, and a short mesoazygos. CONCLUSION Pneumothorax, increa...
