We report a case of intrahepatic splenosis in a 55-year-old man. The lesion in the right lobe of the liver appeared similar to hemangioma on dynamic CT and MRI, but was compatible with normal splenic tissue. On T2WI after the injection of superparamagnetic iron oxide (SPIO), the lesion showed a loss of signal intensity but remained slightly hyperintense relative to the hypointense liver parenchyma. Reports on the radiographic features of intrahepatic splenosis are rare, and a combination of the findings of CT, MRI (including SPIO injection), and angiography might lead to the diagnosis of splenosis.
我们报告一例55岁男性的肝内脾组织异位病例。肝脏右叶的病变在动态CT和MRI上表现类似血管瘤，但与正常脾组织相符。注射超顺磁性氧化铁（SPIO）后的T2WI上，该病变信号强度减低，但相对于低信号的肝实质仍略呈高信号。关于肝内脾组织异位影像学特征的报道很少，CT、MRI（包括注射SPIO）及血管造影检查结果相结合可能有助于脾组织异位的诊断。
