To elucidate magnetic resonance imaging (MRI) findings of the spine with hematopoietic malignancies that require surgery, we retrospectively reviewed the MRI scans in these patients who underwent decompression surgery of the spinal cord or cauda equina. Preoperative MRI scans were obtained from nine patients with spinal involvement by a hematopoietic malignancy who underwent surgery: four with malignant lymphoma and five with multiple myeloma. The marrow involvement pattern, location of signal change of the vertebra, cortical destruction, vertebral fracture, epidural mass formation, paraspinal mass formation, and the wrap-around sign (spread to the extraosseous soft tissues without alteration in the shape of the affected vertebra) were determined by MRI scans. Diffuse marrow involvement (89%), anterior and posterior signal changes of the vertebra (100%), cortical destruction (100%), vertebral fracture (78%), epidural mass formation (78%), and paraspinal mass formation (100%) were commonly observed. The wrap-around sign was seen in only one patient (11%); it was due to vertebral destruction and deformity. Based on these results, we concluded that MRI findings of the spine with a hematopoietic malignancy requiring decompression surgery showed a characteristic diffuse marrow pattern; they also exhibited more expansive and destructive features than previously reported for hematopoietic malignancies without surgery.
