Solitary Osseous Plasmacytoma (SOP) is a rare lesion characterized by a localized accumulation of neoplastic monoclonal plasma cells, without evidence of systemic myelomatosis. It represents 5% of all plasma cell tumors. Its diagnosis relies on three essential elements: radiology, immunohistological examination, and biological investigation. Imaging plays a significant role in all stages of managing osseous plasmacytoma. It aids in detecting and confirming the isolated nature of the lesion, guiding potential biopsy procedures, assessing local tumor extension in pre-therapeutic evaluations, and ensuring monitoring during disease progression. Treatment is primarily based on radiotherapy. Prognosis depends on its progression to multiple myeloma, necessitating regular follow-up of patients with this lesion. This study illustrates a clinical case of a 55-year-old man, discussing the clinical, radiological, and histological aspects of these lesions. Objective: The primary objective is to illustrate the radiological aspect and specify the role of imaging in the diagnosis of solitary osseous plasmacytoma.
