US, portal venous phase CT, and MRI-CSE (MRI with conventional spin-ec
ho sequence) findings in three cases of hepatic involvement in hypereo
sinophilic syndrome are presented. These showed varied imaging finding
s, but portal venous phase CT showed multiple, poorly marginated, and
hypodense hepatic lesions in all three cases, The result suggested tha
t portal venous phase CT is the optimal method for depicting hepatic i
nvolvement.
