This case report illuminates the pivotal role of 2-[¹⁸F]fluoro-2-deoxy-D-glucose ([18F]FDG) PET/CT (Positron emission tomography integrated with computed tomography) scan in diagnosing uncommon and elusive pathologies. Through the detailed exploration of a challenging case, we underscore the significance of this imaging modality in unravelling diagnostic mysteries, guiding clinical decision-making, and ultimately improving patient outcomes. This case highlights the importance of considering haematological malignancies in the differential diagnosis of pyrexia of unknown origin (PUO), especially when accompanied by cytopenia and bone abnormalities. PET/CT scan revealed extent of disease involvement, it also guided to determine the site of bone marrow biopsy and to decide treatment protocol as well as in response assessment.
