【摘要】 目的探讨脾种植的影像学表现特征及病理学基础,提高其诊断的正确率。方法搜集经病理证实的脾种植患者9例,共25个病灶,分析其CT和MR平扫及增强特点,并与病理结果进行对照。结果脾种植患者均有脾切除术病史。脾种植特征性影像表现为:磁共振呈"双低"信号;病灶直径<3cm者,增强早期表现为均匀强化;病灶直径>3cm者,增强早期呈"花斑"样强化;增强延迟期包膜强化,"假脾门"结构的显示。结论对于有腹部外伤或脾切除史,CT或MRI检查示多发软组织肿块的患者,通过结合增强的强化特征及MRI信号特点,有助于提高脾种植的诊断率,避免不必要的手术。更多还原

【Abstract】 Objective To investigate the imaging features and pathological basis of splenic implantation, so as to improve the diagnostic accuracy. Methods From September 2010 to June 2018, 9 patients with splenic implantation confirmed by pathology were enrolled in this study. The CT and MR features of 25 lesions were analyzed and compared with pathological results. Results All of these patients had a history of splenectomy. The characteristic imaging features of splenic implantation were as follows: dual-low signal on magnetic resonance imaging; When the lesion diameter was less than 3 cm, the enhancement of arterial phase was often homogeneous enhancement; If the lesion diameter was > 3 cm, the enhancement of arterial phase was heterogeneous mosaic enhancement; capsular enhancement in the delayed phase and the structure of "pseudo splenic hilum" was shown. Conclusion For patients with multiple soft tissue masses on CT or MRI and with a history of abdominal trauma or splenectomy, according to the features of MRI signal and enhancement, it is helpful to improve the diagnostic rate of splenosis and to avoid unnecessary operation.更多还原
