We report a patient who presented with asymptomatic focal liver lesions and in whom a diagnosis of intrahepatic splenosis was made. This rare condition mostly occurs in patients who previously underwent splenic trauma or surgery. Magnetic resonance imaging (MRI) characteristics suggesting this diagnosis are described. The lesions were mainly hypointense on T1- and hyperintense on T2-weighted images. After administration of small iron oxide particles (SPIO-Endorem), the lesions remained slightly hyperintense relative to the hypointense liver parenchyma but showed a 50% loss in signal intensity. Knowledge of these MRI characteristics may avoid the use of surgical interventions to arrive at the correct diagnosis of these rare liver lesions.
我们报告了一名出现无症状性肝脏局灶性病变的患者，该患者被诊断为肝内脾组织植入。这种罕见疾病多见于既往有脾外伤或脾手术史的患者。文中描述了提示该诊断的磁共振成像（MRI）特征。病变在T1加权像上主要呈低信号，在T2加权像上呈高信号。注射小氧化铁颗粒（SPIO-Endorem）后，相对于低信号的肝实质，病变仍呈轻度高信号，但信号强度降低了50%。了解这些MRI特征可避免通过手术干预来正确诊断这些罕见的肝脏病变。
