Axial T1 in-phase
MRI confirms the sonogram findings of no mass effect and focal fatty sparing appearing as a pseudolesion.
Case Discussion
Look for mass effect and any vascular compromise when viewing a sonogram for lesion vs pseudolesion. MRI is useful to assess whether there is truly a mass or mass effect. In this case, the patient can be told to undertake lifestyle changes for steatosis and that no further workup is necessary.
