Pulmonary arteriovenous malformation (PAVM) is an anomaly condition characterized by abnormal vascular communications between arteries and veins in the lungs. Hereby we describe a 60-year-old female with PAVM. Although the patient was asymptomatic, an abnormal round opacity was found on a chest X-ray film. Computed tomography (CT) of the lung disclosed nodules connected with enlarged vessels. Because PAVM was suspected, the patient was further evaluated by spiral CT coupled with three dimensional reconstruction of the images (3D-CT). As a result, PAVM was clearly visualized and invasive procedures such as angiography was not performed. The present case illustrates that 3D-CT is a diagnostic procedure of choice when PAVM is suspected.
肺动静脉畸形（PAVM）是一种异常状况，其特征为肺部动脉与静脉之间存在异常的血管连通。在此，我们描述一位患有PAVM的60岁女性。尽管该患者无症状，但胸部X光片上发现一个异常的圆形不透光区。肺部计算机断层扫描（CT）显示结节与增粗的血管相连。由于怀疑患有PAVM，该患者通过螺旋CT结合图像三维重建（3D-CT）进行了进一步评估。结果，PAVM清晰可见，未进行诸如血管造影等侵入性检查。本病例表明，当怀疑患有PAVM时，3D-CT是首选的诊断方法。
