Abstract: Intravascular large B-cell lymphoma (IVLBCL) is a rare type of extranodal large B-cell lymphoma. Now, it remains a diagnostic challenge, because of non-specific findings on clinical, laboratory, and imaging studies. Here we present a case of an IVLBCL patient, who presented with fever of unknown origin and had skin involvement, that ¹⁸F-FDG PET/CT showed increased metabolism on systemic subcutaneous fat layer with a SUVmax of 1.29. After five courses of R-CHOP, 18F-FDG PET/CT showed disappearance of the diffuse FDG accumulation on systemic subcutaneous fat layer with a SUVmax of 0.55. These features make this case unique.
