【摘要】：目的探讨软组织原发性淋巴瘤的影像学表现。方法回顾性对照分析2例软组织原发性淋巴瘤患者的CT、MRI、SPECT/CT表现和手术、病理结果,并复习文献。结果 2例软组织原发性淋巴瘤CT平扫及增强上均显示边界不清的等密度影,其中1例肩胛骨骨质受侵犯,CT能清晰显示骨质破坏范围;2例肿块T1WI上均呈等信号,T2WI呈高信号,增强后均匀强化,肿块与周围肌肉分界显示清晰,2例肿块内均未见液化坏死及囊变信号,肿块周围肌肉脂肪间隙均存在;SPECT/CT显像1例显示局部软组织肿块及受侵犯骨质的高代谢,另1例骨代谢呈阴性。结论 MRI能清楚显示软组织原发性淋巴瘤的部位、形态、范围及有无周围组织的侵犯,对临床诊断和治疗有重要价值。软组织原发性淋巴瘤的诊断最终取决于免疫组织学诊断。
[Abstract]:Objective to investigate the imaging features of primary lymphoma of soft tissue.Methods two cases of primary lymphoma of soft tissue were analyzed retrospectively. The CT findings, surgical findings and pathological findings of SPECT / CT were analyzed retrospectively, and the literatures were reviewed.Results in 2 cases of primary soft tissue lymphoma, both plain and enhanced CT showed isodensity with unclear boundary, and one case of scapular bone invasion could clearly show the extent of bone destruction. In 2 cases, the lesions were on the same signal intensity on T _ 2WI, and all of them showed the same signal intensity on T _ 2WI.After enhancement, the boundary between the mass and the surrounding muscles showed clear. In 2 cases, there was no liquefaction necrosis and cystic change signal in the mass. SPECT / CT imaging showed the high metabolism of the local soft tissue mass and the invaded bone in 1 case, and the muscle fat space around the mass was found in 1 case.The other one was negative for bone metabolism.Conclusion MRI can clearly show the location, shape, scope and involvement of surrounding tissues of primary lymphoma of soft tissue, which is of great value in clinical diagnosis and treatment.The diagnosis of primary lymphoma of soft tissue ultimately depends on the immunohistochemical diagnosis.
