The skeletal lesions were found to be caused by multiple myeloma rather than metastatic spread of prostate adenocarcinoma. An MRI can show if normal bone marrow has been replaced by myeloma cells or by a plasmacytoma, especially in the skull, spine, and pelvis. metastases metastasis BACKGROUND: Metastasis and multiple myeloma are common malignant bone marrow lesions which may be difficult to distinguish because of similar imaging findings. A plasmacytoma is a plasma cell tumor growing in bone or soft tissue. We present a patient with coexistent bone metastasis from multiple myeloma and prostate adenocarcinoma who exhibited synchronous bone involvement of both histologies within the same bone lesion, a rare phenomenon that has … • Conventional MRI diagnoses multiple myeloma by assessing the infiltration pattern.
