Value of contrast-enhanced ultrasound in the differential diagnosis of gallbladder lesion

Figure 4 Gallbladder cancer in a 46-year-old male patient. A: B-mode sonography showed a heterogeneously hypoechoic mass in the gallbladder, and the posterior wall of the gallbladder was not very clear; B: Color Doppler ultrasound showed no color Doppler signal in the lesion. According to A and B, a diagnosis of probably malignant was made. C: CEUS showed a heterogeneously hyperenhanced mass with tortuous-type tumor vessel on arterial phase and the boundary of the mass was not clear; D: CEUS showed the enhancement of the lesion is much lower than that of the surrounding gallbladder wall on venous phase. According to C and D, a diagnosis of malignant mass was made. CEUS: Contrast-enhanced ultrasound.
