乳腺原发性非何杰金淋巴瘤钼靶X线及MRI影像表现(附3例报告及文献复习)

目的探讨乳腺原发性非何杰金淋巴瘤的钼靶X线及磁共振的表现特征。方法回顾分析3例经病理证实的乳腺原发性非何杰金淋巴瘤的钼靶X线、MR I资料(3例均有双乳钼靶X线的MLO位及CC位片,其中1例有MR I资料),并结合文献对照分析。结果3例均为单侧发病,其中1例同侧有2个病灶,病灶均为>3 cm的团块灶,中等均匀密度,不规则但无毛刺和钙化,位于乳腺浅表处者无皮肤及乳头受累,T1W I呈均匀低信号、T2W I呈均匀稍高或等信号,强化均匀而明显,时间-信号强度曲线为平台型。结论乳腺原发性非何杰金淋巴瘤的钼靶X线及磁共振表现有一定的特点,治疗前确诊对制订正确的治疗方案有意义。

Mammographic and MRI Appearances of Primary Non-Hodgkin's Lymphoma of Breast

Objective To discuss the features of MRI and molybdenum target X-ray in mammary primary non-Hodgkin's lymphoma.Methods 3 cases of mammary primary non-Hodgkin's lymphoma were studied.The features of MRI and molybdenum target X-ray werecollected and analyzed(all 3 cases had molybdenum target X-ray in MLO site and CC site,one had MRI image).Results All 3 caseslesions were in single side,one case had two lesions in one side.The diameter of all the lesions were more than 3cm.The lesion presented as iso-or slight hyperdensity shadow,and related to breast tissue and density was hemogeneous.The tumor was irregular but no bristle andcalcification.There was no skin and nipple involved in superficial of mammary gland.In T_1WI showed even low signal.In T_2WI showedeven little high or equal signal.Intensity was hemogeneous and obvious.The curve of time-signal intensity was platform pattern.Conclusion The features of MRI and molybdenum target X-ray in mammary primary non-Hodgkin's lymphoma are characteristic and helpful for deciding correct therapy plan.
