title: [Intrahepatic splenosis: a case report].
abstract: 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.
