Abstract:
Objective To assess CT, MR manifestations and diagnostic value in hepatic tuberculosis. Methods CT findings in 12 cases and MR findings in 4 cases with hepatic tuberculosis proved by surgery or biopsy were retrospectively analyzed. Results (1) CT findings: one case of serohepatic type of hepatic tuberculosis was multiple nodular lesions in the subcapsule of liver. Parenchymal type were in 10 cases, including multiple,miliary, micronodular and low density lesions with miliary calcifications in 2 cases, singular, low density mass with multiple flecked calcifications in 3 cases, multiple cystic lesions in 1 case, multiple micronodular and low density lesions fusing into multiloculated cystic mass or “cluster” sign in 3 cases, and singular, macronodular and low density lesion with multiple miliary calcifications in 1 case. One case of tuberculous cholangitis showed marked dilated intrahepatic duct with multiple flecked calcifications in the porta hepatis. (2) MR findings in 4 cases were hypointense on both T 1WI and T 2WI in one case, hypointense on T 1WI and hyperintense on T 2WI in 3 cases. Enhanced MR in 3 cases showed slightly peripheral enhancement or with multilocular enhancement. Conclusions Various types of hepatic tuberculosis had their different imaging findings. The typical CT and MR findings could suggest the diagnosis.
