Pulmonary artery aneurysms (PAAs) are rare but clinically important because their rupture can cause sudden death. This report describes a case of an asymptomatic patient with an unruptured PAA that was successfully diagnosed by dynamic digital chest radiography (DDCR) and was treated surgically. DDCR is an advanced, temporally resolved radiographic technique that offers high-quality fluoroscopy-like images at a low radiation dose. Although noncontrast chest computed tomography revealed only a nonspecific nodule, DDCR delineated this lesion as a pulsatile nodule synchronized with cardiac pulsations, thereby establishing the diagnosis of PAA. This diagnosis was confirmed by computed tomographic pulmonary angiography and surgery.
肺动脉瘤（PAAs）虽然罕见，但在临床上却很重要，因为其破裂可导致猝死。本报告介绍了一例无症状、未破裂的 PAA 患者，该患者通过动态数字胸部射线摄影术（DDCR）成功诊断，并接受了手术治疗。DDCR 是一种先进的、时间分辨的放射技术，可在低辐射剂量下提供高质量的类透视图像。尽管非增强胸部计算机断层扫描仅显示出一个非特异性结节，但 DDCR 描绘了这个病变为与心脏搏动同步的搏动性结节，从而确立了 PAA 的诊断。该诊断通过计算机断层肺动脉造影和手术得到了证实。
