PDFAbstract
Objective To summarize and analyze the imaging findings of extramedullary plasmacytoma(EMP) of the head , neck and thorax in order to improve the ability of imaging diagnosis and differential diagnosis of EMP. Methods A retrospective analysis was performed on imaging data of 6 patients with pathologically confirmed EMP. Results Of all the 6 cases included, 1 neoplasms was located in the oropharynx, 2 in the nasopharynx, 2 in the lungs and 1 in the mediastinum. CT demonstrated well-circumscribed, mildly or obviously enhancing soft tissue masses with dilated vessels around. MRI revealed isoor slightly long T1 and T2 signal intensity, with obviously restricted diffusion on DWI. Low-intensity septa was seen in some lesions and no remarkable necrosis was observed. Contrast-enhanced MRI showed homogenous enhancement of the masses. Conclusion EMP has several imaging features which are nonspecific and a definite diagnosis requires biopsy.Preoperative CT and MRI can help with the measurement of the extent of lesion and involvement of adjacent tissues and lymph nodes, which are of great significance for the early diagnosis and treatment evaluation of EMP.
