Abstract Objective: To explore the clinical and imaging characteristics of plasmacytoma located in the spheno-clival region with multiple myeloma. Methods: The clinical materials and imaging information of three cases clinically confirmed spheno-clival plasmacytoma with multiple myeloma were reported. All of them performed CT and MRI scanning in our hospital. Results: In all of the three cases, homogeneous iso-density mass grew in the spheno-clival region with lytic bone destruction was shown on CT image. All masses were shown clear margin on MRI, two cases were homogeneous iso-intensity on T1WI, and one case was heterogeneous slightly hyper-intensity. One case demonstrated iso-intensity on T2WI, and the other two were shown slightly hyper-intensity. Two cases were performed contrated enhance MRI scanning before operation, and both of them demonstrated obvious homogeneous enhancement. DWI was performed on two cases and showed slightly hyper-intensity. Conclusion: Plasmacytoma located in the spheno-clival region with multiple myeloma is rare. If patients only show up with neurological symptoms, it needs to differential with other tumors frequently occur in this area. To combine analysing its characteristic appearance of MRI with clinical features and laboratory examinations ways would be helpful to improve the diagnostic accuracy, and final diagnosis need to be confirmed by pathological biopsy.
