A 38-year-old man with an anomalous systemic arterial supply from the descending thoracic aorta to the normal basilar segments of the left lower lobe experienced symptoms of progressive exertional dyspnea. Although the pulmonary parenchyma was normal, there was no pulmonary arterial supply to the basilar segments of the left lower lobe. Left lower lobectomy was performed because of worsening left-to-left shunt. Aortography and pulmonary arteriography form the cornerstone for diagnosis, but a less invasive diagnostic method with less patient suffering is high-resolution computed tomography, which might replace bronchography for accurate evaluation of the distribution and patency of the bronchial tree and delineation of the characteristic "Medusa's hair"-like anomalous vascular supply penetrating into the nearly normal pulmonary parenchyma.
一名38岁男性，其降主动脉向左下叶正常基底段发出异常体循环动脉供血，出现进行性劳力性呼吸困难症状。尽管肺实质正常，但左下叶基底段无肺动脉供血。由于左向左分流加重，遂行左下叶切除术。主动脉造影和肺动脉造影是诊断的基石，但一种侵入性较小、患者痛苦较小的诊断方法是高分辨率计算机断层扫描，它可能会取代支气管造影，用于准确评估支气管树的分布和通畅情况，以及描绘穿透几乎正常肺实质的特征性“美杜莎之发”样异常血管供应。
