In a patient with an asymptomatic left upper lobe pulmonary arteriovenous fistula, preoperative chest roentgenograms simulated bronchogenic carcinoma, but no overt feeding vessel was demonstrated. Intraoperatively no lesion could be palpated. Postoperative evaluation revealed a pulmonary arteriovenous fistula. This entity should be considered in the differential diagnosis of single or multiple pulmonary nodules. Careful review of chest roentgenograms for feeding arteries, or draining veins, and observation under fluoroscopy for changing size will aid in diagnosis, and potentially avoid bronchoscopy and possible transbronchoscopic biopsy of these vascular lesions.
在一名患有无症状左上叶肺动静脉瘘的患者中，术前胸部X线片疑似支气管源性癌，但未显示明显的供血血管。术中未触及病变。术后评估显示为肺动静脉瘘。在单发或多发肺结节的鉴别诊断中应考虑到这种情况。仔细复查胸部X线片以寻找供血动脉或引流静脉，并在荧光透视下观察其大小变化将有助于诊断，并有可能避免对这些血管病变进行支气管镜检查及可能的经支气管活检。
