METHODS: CT findings in 12 cases and MR findings in 4 cases of hepatic tuberculosis proved by surgery or biopsywere retrospectively analyzed. RESULTS: (1) CT findings: One case of serohepatic type of hepatic tuberculosis had multiple-nodular lesions in the subcapsule of liver. Parenchymal type was found 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 i case; multiple micronodular and low-density lesions fusing into multiloculated cystic mass or 'cluser' 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 ducts with multiple flecked calcifications in the porta hepatis. (2) MR findings in 4 cases were hypointense on both Tl-weighted imagings and T2-weighted imagings in one case, hypointense on Tl-weighted imagings and hyperintense on T2-weighted imagings in 3 cases. Enhanced MR in 3 cases was slightly shown peripheral enhancementor with multilocular enhancement. CONCLUSION: Various types of hepatic tuberculosis have different imaging findings, and typical CT and MR findingscan suggest the diagnosis.展开更多

However, the diagnosis of this disease must be based on clinical features and confirmed by pathology.展开更多
