We report a case of a 1-year-old girl where computed tomography (CT) angiography demonstrated presence of ill-defined heterogenous soft tissue thickening obliterating the mediastinal fat planes in right peri-hilar region and encasing the hilar right pulmonary artery and its segmental branches leading to marked narrowing with nonvisualization of the right-sided pulmonary veins. The case highlights the features of fibrosing mediastinitis as well as the role of CT angiography in the diagnosis and accurate depiction of the extent of involvement of the mediastinal vasculature and airways.

特发性局灶性纤维化纵隔炎伴单侧肺动脉和静脉受累

我们报告了一名 1 岁女孩的病例，其中计算机断层扫描 (CT) 血管造影显示存在边界不清的异质性软组织增厚，消除了右肺门周围区域的纵隔脂肪平面，并包裹了肺门右肺动脉及其节段导致右侧肺静脉显着变窄的分支。该病例突出了纤维化纵隔炎的特征以及CT血管造影在诊断和准确描述纵隔血管和气道受累范围方面的作用。
