Abstract:
Objective To discuss the imaging appearances and causes of hepatic pseudolesions around the falciform ligament.Methods 40 patients (23 cases of A-type,17 cases of B-type) of hepatic pseudolesion around the falciform ligament examined by CT were collected.Combined with pathology of 2 cases,follow-up of 6 cases,MRI findings in 5 cases,and with the relevant literature reviewes,the density change of CT plain and enhanced scan and the causes of hepatic pseudolesion around the falciform ligament were analyzed retrospectively.Results There were low density in 25 cases,isodensity in 13 cases,high density in 2 cases in arterial phase,density lower than that of liver in 40 cases in portal phase,low or slightly low density in 27 cases and isodensity in 13 case of A-type in delayed phase.Of 40 cases,there were isointense in 2 cases of A-type in any sequence,and no sigal changes on out-phase images;there were intensity decline on out-phase images comparing to in-phase images in 3 cases of B type.Of 6 CT follow-up cases,there were no changes in 2 cases of A-type and shrinked or disappear in 4 cases of B-type;and there were more shrinked in 1 B-type case of MRI follow-up again after one month.Conclusion Hepatic pseudolesion of A-type can be resulted from focal fatty infiltration,and that of B-type can be caused by special blood-supply.They have characteristics in locations,and characteristic imaging appearances on CT and MRI images,and they can be clearly diagnosed generally.
