چکیده
1 of 2 DESCRIPTION A 38-year-old male admitted to the hospital with chest pain for few days. He does not have any signifi cant medical and surgical problems. Physical examination, lab work, imaging studies and exercise cardiolite stress were normal. Eventually, we concluded that this chest pain was most likely secondary to musculoskeletal origin. We found azygos lob incidentally on chest x-ray and computed axial tomography of chest. These images have typical appearance of azygos lobe, fi ssure and vein. The azygos lobe (azygos lobe in fi gures 1 and 2 ) is a uncommon anomaly that is found in 1% of anatomic specimens, 1 on about 0.4% of chest radiographs 2 and 1.2% of high resolution CT. 3 The azygos lobe is a developmental anomaly but not a true accessory lobe. On chest radiographs, azygos fi ssure (azygos fi ssure in fi gure 1 ) is visible as a fi ne convex line and its upper portion has triangular shape due to extrapleural areolar tissue and lower portion has tear-shaped shadow due to azygos vein (azygos vein in fi gure 1 ). Anatomy of azygos lobe is clinically important during thoracic surgical procedures. Cases of spontaneous pneumothorax have reported in patients with azygos lobe.

متن کاملReentrance of Azygos Vein into Azygos Fissure After Pneumothorax.

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 کاملImpressive dilatation of azygos vein due to congenital anomaly of inferior vena cava.
A right-sided thoracotomy was performed for pulmonary metastases in an asymptomatic patient. Preoperative computed tomography (CT) scan showed partial thrombosis or agenesis of the inferior vena cava (Fig. 1). Intra-operatively, an impressive dilation of the azygos vein was noted (Fig. 2). The azygos vein or superior vena cava was not invaded by tumour. Fig. 1. Preoperative thoracic CT scan sho...
متن کاملCatheter ablation of typical atrial flutter with the superior approach in a patient with inferior vena cava interruption
Inferior vena cava (IVC) interruption is a rare condition that might pose difficulties during typical flutter ablation. When azygos vein continuation is present ablation via the femoral route could be performed. In the absence of azygos vein continuation, typical atrial flutter ablation via a superior approach from the SVC is feasible.
