Cases of inferior phrenic artery-to-pulmonary artery fistulas and those complicated by massive hemoptysis have been rarely reported. A 38-year-old man presented to our hospital with a chief complaint of coughing. Computed tomography (CT) revealed a nodule in the left lower lobe, and contrast-enhanced CT showed inflow of contrast medium into the nodule. CT angiography detected an aneurysm associated with a left inferior phrenic artery-to-left pulmonary artery fistula. Transcatheter arterial embolization (TAE) was performed to prevent hemoptysis. Hemoptysis did not occur during the 2-year follow-up. We report a rare case of asymptomatic aneurysm associated with a left inferior phrenic artery-to-left pulmonary artery fistula, which was successfully treated using TAE to prevent hemoptysis.
膈下动脉至肺动脉瘘合并大量咯血的病例鲜有报道。一名38岁男性因咳嗽为主诉前来我院就诊。计算机断层扫描（CT）显示左肺下叶有一个结节，增强CT显示造影剂流入该结节。CT血管造影检测到一个与左膈下动脉至左肺动脉瘘相关的动脉瘤。为预防咯血进行了经导管动脉栓塞术（TAE）。在2年的随访期间未发生咯血。我们报告了一例罕见的与左膈下动脉至左肺动脉瘘相关的无症状动脉瘤病例，该病例通过TAE成功治疗以预防咯血。
