We present a patient who had suffered from mild hemoptysis for six years. Abnormal bronchovesicular breath sounds over the left lower lung filed were noted. The chest film also revealed infiltration over the left lower lung field. High-resolution computed tomography (HRCT), aortogram and pulmonary angiography demonstrated anomalous arterial supply to the basilar segments of the left lower lung without coexistence of pulmonary sequestration. Only total nine cases have been reported in English or Chinese literature. The improvement of diagnostic method has enabled an accurate diagnosis before operation with non-invasive examination. Also, this congenital abnormality may not be so rare if meticulously surveyed.
我们报告一名有六年轻度咯血病史的患者。左下肺野可闻及异常支气管肺泡呼吸音。胸部X线片也显示左下肺野有浸润影。高分辨率计算机断层扫描（HRCT）、主动脉造影和肺血管造影显示左下肺基底段存在异常动脉供血，且无肺隔离症并存。英文或中文文献中仅报道过9例。诊断方法的改进使得在术前通过无创检查就能做出准确诊断。而且，如果仔细检查，这种先天性异常可能并不罕见。
