The magnetic resonance imaging (MRI) differential diagnosis of intrahe
patic biloma from intrahepatic subacute hematoma has been reported in
two cases. The biloma was heterogenously intense on T1-weighted images
and homogenously hyperintense on T2-weighted images, The hematoma was
hyperintense on the both T1- and T2-weighted MR images. The clinical
significance of this MRI difference is that intrahepatic biloma needs
drainage, whereas intrahepatic hematoma can heal spontaneously.
