We present a case of azygos vein continuation with aneurysm of the azygos vein simulating a tumor in the right upper mediastinum. The dynamic CT examination initially showed a structure of malignant appearance during the early arterial phase. Further dynamic CT revealed marked enhancement of the mass during the late venous phase, suggesting a vascular structure. Confirmation of diagnosis was made by MRI using a fast gradient echo imaging technique in cine mode, showing turbulent flow in the azygos aneurysm, and contrast-enhanced MR angiography, demonstrating a dilated azygos vein. Dynamic CT has a potential pitfall in the diagnosis of vascular structures.

Resection and Reconstruction of the Inferior Vena Cava Using a Tunneled Peritoneal Graft for Renal Tumor With Thrombus: Venous Compensation via the Azygos Vein Following Early Graft Occlusion.

Inferior vena cava (IVC) invasion by tumor thrombus poses a significant surgical challenge, often requiring vascular reconstruction. Standard methods, including prosthetic and autologous vein grafts, have limitations such as infection risks, anticoagulation demands, and increased costs. We present the case of a 66-year-old male with a right renal tumor (T3bN0M0, Neves Zincke II) and gross hematuria, who underwent radical nephrectomy with open thrombectomy.

Heterotaxy syndrome is characterized by abnormal left-right arrangement of thoracoabdominal organs and is frequently associated with complex cardiac anomalies. However, cases with predominant extracardiac manifestations are increasingly recognized. This report describes a 20-year-old female of North African descent with consanguineous parentage, who presented with chronic cough and exertional dyspnea persisting over several years.

Background And Purpose: Symptoms indistinguishable from behavioral-variant frontotemporal dementia (bvFTD) can develop in patients with spontaneous intracranial hypotension associated with severe brain sagging. An underlying spinal CSF leak can be identified in only a minority of these patients and the success rate of nondirected treatments, such as epidural blood patching and dural reduction surgery, is low. The disability associated with bvFTD sagging brain syndrome is high and, because of the importance of the venous system in the pathophysiology of CSF leaks in general, we have investigated the systemic venous circulation in those patients with recalcitrant symptoms.

Polysplenia syndrome is a rare congenital disease with multiple systemic developmental abnormalities. Their occurrence and development are closely related to embryonic development. The prognosis of the disease depends on its anatomical structure, and the presence or absence of concomitant cardiac malformations also has a prognostic impact.

Background: Esophageal atresia is one of the most common life-threatening congenital malformations and is defined as an interruption in the continuity of the esophagus with or without fistula to the trachea or bronchi. Definitive treatment is surgical ligation of the fistula if present and esophageal end-to-end anastomosis of the two pouches, thereby reconstructing the continuity of the esophagus. During this procedure, the surgeon may choose to either ligate or preserve the azygos vein, a major draining vein for the esophagus and surrounding structures, but no definitive consensus on the matter exists.
