We present the unusual case of a 72-year-old woman whose chest X-ray showed an abnormal left hilar shadow. A pulmonary angiogram revealed an aneurysm in the pulmonary artery with a diameter of 55 mm that extended from the main pulmonary trunk to its bifurcation. Mild pulmonic stenosis with a systolic pressure gradient of 18 mmHg across the pulmonic valve was recognized. Mild dilatation of the ascending aorta was also present. The pressure gradient across the pulmonic valve was lower than is typical for an aneurysmal dilatation, suggesting that this patient represented a case of idiopathic pulmonary artery dilatation. We suspected the presence of a congenital structural alteration common to the pulmonary artery and the ascending aorta.
我们报告了一例不同寻常的病例，一名72岁女性，其胸部X光显示左肺门阴影异常。肺血管造影显示肺动脉有一个直径55毫米的动脉瘤，从主肺动脉延伸至其分叉处。经确认存在轻度肺动脉瓣狭窄，跨肺动脉瓣的收缩压梯度为18 mmHg。升主动脉也有轻度扩张。跨肺动脉瓣的压力梯度低于动脉瘤样扩张的典型值，提示该患者为特发性肺动脉扩张病例。我们怀疑肺动脉和升主动脉存在共同的先天性结构改变。
