Abstract: Objective To investigate the diagnostic value of CT plain scan + dynamic enhancement for hepatic tuberculosis. Methods The imaging findings of 15 cases of hepatic tuberculosis confirmed by surgery or puncture pathology were retrospectively analyzed. There were 10 males and 5 females with CT scan and dynamic enhanced scan of the upper abdomen. Results In 4 cases, there were single nodules in the liver parenchyma; 9 cases showed multiple nodules in the liver; 2 cases were located under the liver capsule. The enhanced scan showed mild inhomogeneous enhancement of the arterial phase in 2 cases, and the degree of enhancement in the portal vein and lag phase was reduced. The type of enhancement was “fast-forward and rapid-out”; 2 cases were mildly intensified in the arterial phase, and the portal vein and delayed phase were associated with the liver. The essence was basically similar, the type of enhancement was “slow-in and slow-out”; 4 cases showed ring-shaped enhancement; 5 cases showed “syncope” in the arterial phase; 1 case showed no obvious enhancement in arterial phase, and the portal vein and delayed phase showed lesions. There are mild enhancement and no obvious enhancement in 3 lesions. Calcification in 4 lesions. Conclusion CT plain scan and enhanced examination have high diagnostic value for hepatic tuberculosis. According to the different enhancement features of lesions, the pathological features of lesions can be judged.
