Abstract

INTRODUCTION

The azygos vein arises below the diaphragm from the ascending lumbar and right subcostal veins, playing a critical role in venous drainage and being susceptible to anomalies.

CASE PRESENTATION

A 40-year-old woman, admitted after trauma, had an incidental finding of an enlarged azygos arch on CT, confirmed by CT angiography and managed conservatively.

DISCUSSION

The embryologic development and complex imaging features of the azygos system may mimic mediastinal masses; advanced CT techniques enable accurate differentiation.

CONCLUSION

Advanced imaging prevented unnecessary invasive procedures and underscored the importance of a timely, systematic diagnostic approach.

摘要

引言

奇静脉在膈肌下方由腰升静脉和右肋间静脉汇合而成，在静脉引流中起关键作用，且易出现变异。

病例介绍

一名40岁女性因外伤入院，CT偶然发现奇静脉弓增大，经CT血管造影证实后采取保守治疗。

讨论

奇静脉系统的胚胎发育和复杂影像学特征可能类似纵隔肿块；先进的CT技术有助于准确鉴别。

结论

先进的影像学检查避免了不必要的侵入性操作，强调了及时、系统的诊断方法的重要性。
