A 47-year-old woman presented with hemoptysis and her chest X-ray films showed an opacity suggesting a mass in the left lower lung field. Based on radiographic investigations, the mass was diagnosed as an aneurysm develop in an anomalous vessel and was considered to be a Pryce type I pulmonary intralobar sequestration. Resection of the left lower lobes was performed and the aneurysm was found to be filled with thrombus. It is rare for an aneurysm to form in an aberrant vessel. This complication may have been the result of regional sclerosis affecting the anomalous artery as well as systemic atherosclerosis.
一名47岁女性因咯血就诊，胸部X线片显示有一不透光区，提示左下肺野有一肿块。根据影像学检查，该肿块被诊断为异常血管内形成的动脉瘤，被认为是普赖斯I型肺叶内隔离症。行左下叶切除术，发现动脉瘤内充满血栓。动脉瘤在异常血管中形成较为罕见。这种并发症可能是局部硬化累及异常动脉以及全身动脉粥样硬化的结果。
