Abstract | OBJECTIVE: METHODS: Twenty-four hepatic TB lesions in 15 patients were studied with conventional ultrasonography ( CUS) and contrast-enhanced ultrasonography (CEUS). Pathologic characteristics of the lesions were evaluated and were then correlated with enhancement patterns. RESULTS: The appearance of hepatic TB on CUS was variable and nonspecific with respect to the shape, echogenicity, and boundary of the lesions. The diameters of the lesions obtained from CEUS were statistically larger than those from CUS, with largest diameters +/- SD of 4.2 +/- 1.8 and 3.1 +/- 1.9 cm, respectively. During the arterial phase, 13 of 24 lesions (54.2%) showed a rapidly and markedly enhanced rim with a hypoenhanced or nonenhanced center; 9 of 24 lesions (37.5%) showed transient enhancement of the whole lesion with inconsistent intensities. During the portal phase, most lesions showed distinct wash-out of the contrast agent and maintained a hypoechoic appearance. Pathologic studies confirmed that the different appearances of hepatic TB on CEUS were related to the different pathologic stages of the lesions. CONCLUSIONS: Findings of hepatic TB on CEUS may be helpful in differentiating the diagnosis from other hepatic focal lesions. Correlation with pathologic findings would enrich the understanding of CEUS findings in hepatic TB.
