Patient was known for remote history of chronic lymphocytic leukemia (CLL), previously treated. Scan revealed diffusely increased abnormal tracer uptake throughout the marrow of the axial and proximal appendicular skeleton. Bone marrow biopsy revealed relapsed CLL. We present a rare case of relapsed CLL incidentally detected on 68Ga-DOTATATE PET/CT. Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.
