Multiple T2 hyperintense, T1 hypointense lesions throughout the spine, including the sacrum.
Enhancing destructive lesions in the bodies of T8, T9 and T10 extending into the right pedicles and laminae with intradural extension, causing cord compression. Additional soft-tissue extension into the paravertebral muscles at these levels.
4 cm mass in the lower pole of the left kidney.
Skeletal metastases are common and MRI is frequently performed to assess for cord compression.
Renal cell carcinoma is one of the typical primaries, along with lung, breast and prostate, to metastasize to the spine.
