【摘要】 目的研究原发性骨淋巴瘤及淋巴瘤骨浸润的CT、MRI表现,探讨CT、MRI对骨淋巴瘤的诊断价值。方法经病理证实的骨淋巴瘤23例,其中原发性骨淋巴瘤5例,全身淋巴瘤伴发骨浸润18例,回顾性分析各类病例CT、MRI表现。结果5例原发性骨淋巴瘤均为单发,分别位于股骨、髂骨、肱骨、胸骨和上颌骨,均为浸润性骨质破坏,可伴有少许硬化;18例继发性骨淋巴瘤单骨发生10例,8例为多发骨浸润,其中溶骨型5例,浸润型6例,硬化型2例,混合型5例,病变MRI表现为T1WI呈等或稍低信号,T2WI脂肪抑脂序列呈高信号,肿瘤可呈明显均匀或不均匀强化。结论骨淋巴瘤浸润具备一定的影像学特点,CT、MRI在骨淋巴瘤诊断和鉴别上有着重要价值。更多还原

【Abstract】 Objective To study the CT,MRI imaging findings of bone lymphoma,and to evaluation the value of CT/MRI in bone lym-phoma diagnosis.Methods 23 cases of bone lymphoma proved by pathology were collected,which including 5 cases primary bone lymphoma and 18 cases secondary bone lymphoma.The imaging findings were retrospectively analyzed.Results 5 cases of primary bone lymphoma were solitary lesion,bone lesions were infiltra-tive with soft-tissue masses.10 cases of secondary bone lymphoma were solitary lesion,8 cases were polyostotic lesions.Osteolytic lesion in 5 cases,infiltrative in 6 cases,selerotic in 2 case and mixed findings in 5 cases.Most of lesions showed equal or low T1 signal intensity and high T2 signal intensity in T2WI-FS.Le-sions showed significantly homogeneous or in-homogeneous enhancement.Conclusion Bone lymphoma can involved single or multi-lesions.They had some typical features in CT and MRI image.CT and MRI were valuable of bone lymphoma demonstrating or diagnosis.更多还原
