Reason: Multiple myeloma staging History: Multiple myeloma staging Several sequences are limited by patient motion artifact. There is a subcentimeter focus of increased bone marrow signal abnormality on fluid sensitive sequences within the right ilium which demonstrates decreased signal abnormality on T1-weighted images and enhancement on postcontrast sequences, suspicious for a myelomatous deposit. There are additional foci of increased signal abnormality on fluid sensitive sequences in the L4 vertebral body, seen on the large field-of-view images, however, these are not completely included in the field-of-view on the additional sequences and are incompletely characterized. Please refer to the dedicated MRI lumbar spine report for additional details. Heterogeneous bone marrow signal within the image lower lumbar spine, sacrum, and left and right ilium likely reflect residual islands of red marrow, however, diffuse myelomatous involvement cannot be completely excluded. The prostate is enlarged and heterogeneous. There is enlargement and dilation of the right seminal vesicle which is nonspecific.
7 mm focus of enhancing bone marrow signal abnormality in the right ilium is suspicious for a myelomatous deposit. Other findings as described above.
