主　　题：Liver Extramedullary hematopoiesis Signal intensity Magnetic resonance imaging Case report 

摘      要：BACKGROUND Extramedullary hematopoiesis rarely occurs within the liver alone,and is easily *** radiological literature on this disease is exclusively case *** is a paucity of literature on the role of magnetic resonance imaging(MRI).The most common imaging modalities used are computed tomography and *** report aims to provide more data on the appearance of extramedullary hematopoiesis using MRI to help radiologists establish the *** SUMMARY Three patients(one male and two females)were incidentally found to have a hepatic mass or nodule,without hepatomegaly or *** tests including liver function,serum hepatic tumor markers,and hepatitis serologic markers were *** MRI scans,all lesions showed lower signal intensity on in-phase images than on out-phase *** case showed changes in signal intensity on T2 weighted images(WI)and diffusion WI,which shifted from hyperintensity to hypointensity with size enlargement between two rounds of imaging *** lesions exhibited different enhancement patterns on dynamic contrast enhancement *** The MRI signal change and in-/out-phase image might provide useful information and help radiologists establish the diagnosis of intrahepatic extramedullary hematopoiesis.
