The empty azygos fissure.
The azygos fissure is typically visible on chest radiography as a right paramediastinal supernumerary line in projection of the right lung apex. The azygos vein, located at the bottom of the fissure, is visible as a teardrop-shaped opacity. The empty azygos fissure is a rare finding. It is the consequence of the displacement of the azygos vein out of the fissure with a close paramediastinal pos...
متن کاملReentrance of Azygos Vein into Azygos Fissure After Pneumothorax.
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...
متن کاملThe Azygos Lobe
Wrisberg (1778) was the first to give the anatomical description of this lobe. Stibbe (1919) reviewed 23 cases from the literature including one of his own. Since 1923 radiologists have often reported this abnormality. Litten (1929) gives a frequency of 0.07 per cent, while Le Bourdelles and Jalet (1931) give 2.6 per cent for the occurrence of the azygos lobe in chest radiographs. The cases rep...
متن کاملThe Abnormally Situated Azygos Vein
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 ...
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.
