Although giant-cell tumor (GCT) of the bone was originally classified as a benign tumor, metastasis has been reported. The radiographic features usually comprise parenchymal solitary or multiple nodules that are round-to-oval nodular opacities of homogeneous density in patients with GCT. However, the patient described in this case presented with a hypervascular mass with feeding vessels and hemothorax, which are common features of pulmonary arteriovenous malformation. To the best of our knowledge, cases of pulmonary metastases presenting as a pulmonary arteriovenous malformation have not been reported. Here, we report a case of giant-cell tumor of the bone that exhibited histologically benign pulmonary metastases and mimicked an arteriovenous malformation.
尽管骨巨细胞瘤（GCT）最初被归类为良性肿瘤，但已有转移的报道。GCT患者的影像学特征通常包括实质性的单发或多发结节，表现为密度均匀的圆形至椭圆形结节状不透明影。然而，本病例中的患者表现为具有供血血管的高血运肿块和血胸，这些是肺动静脉畸形的常见特征。据我们所知，尚未有表现为肺动静脉畸形的肺转移病例的报道。在此，我们报告一例骨巨细胞瘤，其组织学上表现为良性肺转移，并酷似动静脉畸形。
