Bone metastases can present in a wide variety of appearances across all imaging modalities. We present a unique appearance of a distal femoral metastasis in a patient who initially complained of knee pain. The radiographic and CT findings were initially suspicious for calcium pyrophosphate deposition (CPPD) arthropathy; however, an MRI demonstrated multiple lesions with a lamellated appearance confirmed on biopsy to be metastatic disease. This unusual lamellated appearance has not been previously described. We present this case to help distinguish this entity radiographically and better classify this finding as a manifestation of metastatic disease.
骨转移在所有成像模态中可呈现出多种多样的表现。我们报告一例股骨远端转移瘤的独特表现，该患者最初主诉膝关节疼痛。X线和CT表现最初怀疑为焦磷酸钙沉积（CPPD）关节病；然而，MRI显示多个具有分层外观的病灶，活检证实为转移性疾病。这种不寻常的分层外观此前尚未见报道。我们展示此病例以帮助在影像学上鉴别该实体，并更好地将此发现归类为转移性疾病的一种表现。
