Multiple myeloma (MM) is a hematologic malignancy that accounts for 1-2% of all cancers and 17% of hematologic malignancies worldwide. It predominantly affects older adults, with a higher incidence in males and African American populations. Clinical manifestations often include bone pain, anemia, renal insufciency, and hypercalcemia, due to the proliferation of malignant plasma cells. Diagnosis is based on clinical, laboratory, and imaging ndings, including the detection of monoclonal proteins in serum or urine, and the presence of clonal plasma cells in bone marrow biopsy. Imaging techniques such as MRI and PET/CT play a key role in identifying osteolytic lesions and assessing disease progression. The management of MM has advanced with the use of autologous hematopoietic cell transplantation, triple drug regimens, and maintenance therapies.
