Abstract:
Objective To investigate the imaging features of solitary plasmacytoma of bone(SPB),to improve the ability of imaging diagnosis of SPB.Methods Retrospective analysis by surgery or biopsy pathology confirmed 16 cases of patients with SPB clinical and imaging data.Results All lesions were single.X-ray and CT scan showed swelling bone destruction,boundary more clearly,in all cases no periosteal reaction.Compared with the muscle signal,T1-weighted images showed equal or slightly lower signal,T2-weighted images showed high signal.All patients had no significant peritumoral edema in the bone marrow,but were seen varying degrees of soft tissue invasion.Enhanced MR scan,most cases showed significantly enhanced uniformity.Conclusions SPB presents osteolytic destruction,expansive growth and soft tissue mass without bone reaction and peritumoral edema.X-ray,CT and MR together might improve the diagnostic accuracy of SPB.
