| 目的 提高对脾组织植入及其MRI表现的认识。方法 报告3例经病理证实的脾组织植入的MRI表现,结合文献复习探讨其发生的病理基础。结果 3例均有脾外伤,脾切除病史(18个月至27年),MRI检查表现为左上腹部包块,1例为多发包块。病灶在SE序列T1WI表现为低信号,T2WI表现为稍高信号,Gd-DTPA增强扫描,在动脉期呈明显强化,延迟期呈均匀中度强化。1例行超顺磁氧化铁(SPIO)增强扫描,脾组织植入在T2WI呈明显的低信号。结论 脾组织植入MRI表现为脾外伤、手术后出现的腹部包块,MRI表现为在各个扫描序列上与正常脾脏一致。诊断的关键在于提高对该病的认识。 |

| Objective To describe the MRI features of splenosis. Methods The MRI features in 3 cases of splenosis were reported,and literature was reviewed. Results All of them had prior abdominal trauma and splenectomy (from 18 month to 27 years).MRI showed abdominal masses.The lesions were showed hypointense on T1WI and hyperintense on T2WI.After administration of Gd-DTPA,the lesions showed hyperintenses in early phase and mordeate enhancement in late phase.One case were also underwent superparamagnetic iron oxide (SPIO) contrast enhanced,the lesions remained slightly hyperintense relative to the hypointense liver parenchyma. Conclusion Splenosis was featured as abdominal masses after splenectomy.MRI fueatures of splenosis were similar to normal spleen.The key of the dignosis is to enhance the understandings of this dieases. |
