The patient underwent a PET-CT scan.<\/p>\n<p>What is the most probable diagnosis?<\/p>\n<p>This is a \u201csuperscan\u201d, a term applied to skeletal scintigraphy whenever intense radiotracer uptake in axial skeleton and decreased uptake in soft tissues and kidneys is noted. The same image can be found in \u00b9\u2078F-fluorodeoxyglucose (FDG) positron emission tomography (PET)\/computed tomography (CT) in several conditions, mostly metastatic tumors of prostate, stomach and breast. It is also recorded whenever there is activation of the bone marrow by erythropoiesis- and colony-stimulating factors or in rebound activation after recent myelosuppressive chemotherapy. Persistent fever, either from infection or from other causes, may also provide a similar situation, probably due to interleukin-mediated upregulation of glucose transporters. Recently many PET\/CT \u201csuperscan\u201d cases have been reported in patients with hematological malignancies, i.e. non-Hodgkin lymphomas and acute lymphoblastic leukemia.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1767 aligncenter\" src=\"https:\/\/haema-journal.gr\/wp-content\/uploads\/2022\/11\/06_Image_Megalakaki_Eik-1-e1667387258197.jpg\" alt=\"\" width=\"750\" height=\"757\" srcset=\"https:\/\/haema-journal.gr\/wp-content\/uploads\/2022\/11\/06_Image_Megalakaki_Eik-1-e1667387258197.jpg 750w, https:\/\/haema-journal.gr\/wp-content\/uploads\/2022\/11\/06_Image_Megalakaki_Eik-1-e1667387258197-297x300.jpg 297w, https:\/\/haema-journal.gr\/wp-content\/uploads\/2022\/11\/06_Image_Megalakaki_Eik-1-e1667387258197-150x150.jpg 150w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><\/p>\n<p style=\"text-align: center;\"><strong>Figure 1<\/strong><\/p>\n<p>This particular patient had an overwhelming relapse of DLBCL, as a bone marrow biopsy showed heavy infiltration by lymphoma cells, as well as severe hemophagocytosis.
