A child with the isolated anomaly of azygos continuation of the inferior vena cava is presented. The interest of this abnormality lies in its detection as a mediastinal mass on the chest radiograph. Computed tomography with intravenous contrast enhancement is the method of choice to diagnose this venous anomaly. Awareness of the caval-azygos abnormality is important to surgeons and cardiologist...

Discussion Although anomalies of the inferior vena cava are commonly discovered during imaging for other diseases,'-3 it seems that the anomaly in this patient directly contributed to the pathogenesis of the haemoptysis. The bronchial venous system communicates freely with the pulmonary veins and alveolar capillaries on one side, and with the azygos vein on the other." A direct communication be...

Aneurysm of the azygos vein is a rare cause of mediastinal mass that is normally detected radiologically in asymptomatic patients. In some cases a diagnosis is made by noninvasive methods, such as computed tomography and magnetic resonance. However, in the present case imaging revealed what appeared to be a solid mass. When the mass had been excised by thoracotomy, the histopathologic diagnosis...

UNLABELLED We present a rare complex variation of the inferior vena cava and internal iliac veins demonstrated by a multidetector computed tomography. It was shown that patient had double inferior vena cava with azygos continuation of the right inferior vena cava, retroaortic left renal vein and the left and right internal iliac veins converged and drained to the right external iliac vein throu...

In man, the azygos vein is described as ascending on the right side of the vertebral column until it curves anteriorly over the right bronchus to end in the superior vena cava. However, it has been observed that frequently the azygos vein is found to run part of its course on the left side of the midline. No description of this course has been found in current anatomical textbooks or other lite...

The triad of extrapulmonary infection, contiguous septic vein thrombosis, and septic pulmonary embolism is a rare complex but associated with significant morbidity and mortality. Septic azygos vein thrombosis is extremely rare and potentially serious since it may also cause pulmonary emboli and sudden death. We report a case of a 32-year-old woman with history of IV drug abuse who presented wit...

Persistent left cranial vena cava (PLCVC) is an uncommon congenital thoracic venous anomaly in dogs. This study examines the clinical and CT findings of dogs diagnosed with PLCVC incidentally. In this study, complete type of PLCVC was diagnosed in 26 dogs with CT angiography. Shih tzu (17 cases) and Pekingese dogs (3 cases) were overrepresented. There was no gender predisposition, and the avera...
