Malignant rhabdoid tumor of the kidney is a rare aggressive malignancy with poor prognosis. We describe FDG PET/CT findings in a case of malignant rhabdoid tumor of the renal allograft with regional lymph node and pulmonary metastases. The primary renal tumor and lymph node metastases showed intense FDG uptake. The pulmonary metastases showed minimal FDG uptake due to small size. Posttreatment FDG PET/CT showed no evidence of residual disease. This case suggests that FDG PET/CT may be useful in the management of malignant rhabdoid tumor from the transplanted kidney.
肾恶性横纹肌样瘤是一种罕见的侵袭性恶性肿瘤，预后不良。我们描述了一例肾移植后发生的恶性横纹肌样瘤伴区域性淋巴结和肺转移的 FDG PET/CT 表现。原发性肾肿瘤和淋巴结转移灶摄取 FDG 明显。由于转移灶较小，肺转移灶摄取 FDG 较少。治疗后 FDG PET/CT 未见残留疾病。该病例提示 FDG PET/CT 可能有助于肾移植后恶性横纹肌样瘤的治疗管理。
