Abstract:

Objective

To explore the value of contrast enhanced ultrasound in the diagnosis of gallbladder adenomyomatosis.

Methods

Twenty-three patients with pathologic diagnosis of gallbladder adenomyomatosis were included in this study. The features of conventional ultrasound and contrast enhanced ultrasound were observed and the accuracy rates of conventional ultrasound and contrast enhanced ultrasound were compared.

Results

The typical conventional ultrasound features for gallbladder adenomyomatosis included the localized thickness of gallbladder, intramural small anechoic area, and intralumenal echogenic foci with comet tail. The accuracy for conventional ultrasound was 69.6% (16/23). The typical contrast enhanced ultrasound features were the heterogeneous enhancement with scattered small non-enhanced areas on both arterial phase and venous phase. The accuracy of contrast enhanced ultrasound was 95.7% (22/23), which was significantly higher than that of conventional ultrasound (χ2=5.447, P<0.05).

Conclusions

Both conventional ultrasound and contrast enhanced ultrasound had typical features for gallbladder adenomyomatosis. The diagnostic efficiency of contrast enhanced ultrasound was significantly better than that of conventional ultrasound.
