Multiple Myeloma Muscle Infiltration with Atypical Presentation: Lower Extremity Treatment with Three Arc VMAT Radiotherapy Plans

Extramedullary myeloma can occur in a variety of organs; however, muscle involvement is rarely reported. We present a case of multiple myeloma patient who progressed with extramedullary lower extremity muscle involvement while receiving chemotherapy. Pathologic plasmacytoma was confirmed by involvement biopsy. Palliative radiotherapy was planned for the patient who complained of severe pain, weakness and edema in the leg. Due to the very large radiotherapy field, a special three-arc VMAT plan was made for the patient.
