Abstract:
Objective To discuss CT and MRI manifestations and the differential diagnosis of hepatic tuberculosis.Methods The imaging manifestations of hepatic tuberculosis proved by pathology in 2 cases were analyzed retrospectively with literatures review.The plain and contrast-enhanced CT scans were performed in 2 cases and 1 case underwent plain MRI.Results On plain CT scan,the lesion was non-homogeneous low density with even more low density in the center in 1 case,and nearly isodensity in another case.On contrast-enhanced CT scan,the lesions were no enhancement in arterial phases,and slight enhancement in venous phase and balance phase.In 1 case,slight enhancement was also shown surrounding the necrotic area.On MR plain scan,the lesion demonstrated low signal intensity on T_1WI,iso-and high mixed signal intensity on T_2WI.Conclusion Hepatic tuberculosis is rare seen,so it is easy to misdiagnosis.CT and MRI scanning can demonstrate some features of hepatic tuberculosis,especially dynamic enhanced scanning is very helpful in diagnosis and differential diagnosis.
