| [Abstract] Objective: To study the MRI findings of extramedullary plasmacytoma in the sinonasal and orbit.Materials and Methods: The MRI and CT findings of 4 patients with extramedullary plasmacytoma in sinonasal and orbit were retrospectively reviewed. All cases were proved by pathology.Results: The tumor mainly occurred in sphenoid sinus in 1 case, in maxillary sinus and nasal cavity in 1 case, in orbital 1 case, cranium, nasal and orbital were involved 1 case. On MRI, the tumors were usually isointensity on T1WI and T2WI. After administration of contrast medium, the tumors showed midrange or strongly enhancement. Among 2 cases dynamic contrast MRI, dynamic contrast curve showed rapid ascend and slow descend 1 case, rapid ascend and rapid descend 1 case. On CT of 3 cases, showed osteolytic bone destruction adjacent to the tumors.Conclusion: The MRI findings of extramedullary plasmacytoma in sinonasal and orbit are characteristic, but lack of specificity. The final diagnosis depend on the pathology. MRI is helpful in demonstrating the invaded extent of the lesions and can provide more comprehensive information in diagnosis and therapy of the tumor. |
