Bone marrow uptake was also represented as multiple focal increased spots without any corresponding lytic or sclerotic lesions in CT. MRI revealed a high and homogeneous T2 signal within the bone marrow, without any contrast-enhanced or diffusion-restricted lesions. Further workup, including a bone marrow biopsy, revealed the diagnosis of myelodysplastic syndrome. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
