Abstract:
Objective To retrospectively analyze CT and MR appearances of hepatic adenoma,and to study the causes of misdiagnosis with review of relative literatures.Methods CT and MRI data of 8 patients with pathologically confirmed hepatic adenoma were retrospectively analyzed.Pre-and post-contrast tri-phase (arterial,portal venous and delayed) CT scans and routine MR .scan were performed in all 8 patients,and proton magnetic resonance spectroscopy (~1H-MRS) was performed in 2 patients.Results Typical demonstrations were found in 4 patients who were correctly diagnosed.Among the others with atypical findings,3 patients were misdiagnosed as liver cancer and 1 as focal nodular hyperplasia (FNH) .The ~1H-MRS curves of 2 adenoma tumor showed that the peak of choline of tumor tissue had no significant difference comparing with that of normal liver tissue around the tumor tissue.Conclusion CT and MRI findings of hepatic adenomas have some characteristics,but atypical manifestations lead to misdiagnose.~1H-MRS may be helpful for the differential diagnosis of hepatic adenoma.
