Primary angiosarcoma of the kidney is a rare aggressive malignancy. We describe MRI and FDG PET/CT findings in a case of primary renal angiosarcoma with hepatic, pulmonary, and bony metastases. The large primary tumor showed extensive necrosis and increased FDG uptake in the nonnecrotic components. Multiple metastatic lesions in the liver, lung, and bones were detected by FDG PET/CT. Most of the hepatic metastases seen on MRI were missed on FDG PET/CT due to low FDG avidity.
肾脏原发性血管肉瘤是一种罕见的侵袭性恶性肿瘤。我们描述了一例伴有肝、肺和骨转移的原发性肾血管肉瘤的 MRI 和 FDG PET/CT 表现。大的原发性肿瘤显示广泛坏死和非坏死成分中 FDG 摄取增加。FDG PET/CT 检测到肝脏、肺部和骨骼中的多个转移性病变。由于 FDG 摄取低，MRI 上看到的大多数肝转移在 FDG PET/CT 上漏诊。
