Overview
Ultrasound may be helpful in the diagnosis of gallbladder cancer. Findings on an ultrasound suggestive of gallbladder cancer include polypoid gallbladder lesions, Mass in the gallbladder
and Asymmetric wall thickening of the gallbladder.
Ultrasound
- when gallbladder pathology is suspected ultrasonography is most commonly the first choice for screening.
- Sensitivity and specificity of ultrasound screening is 85% and 80%.
- A High-resolution contrast-enhanced ultrasonography identifies up to 70–90% of polypoid gallbladder lesions.[1]
- Gallbladder cancer on ultrasound have one of the following feartures[2]
- 1) A mass in the gallbladder
- 2) A polyp in the gallbladder
- 3) Asymmetric wall thickening of the gallbladder
- Polyps which are over 1 cm in diameter have higher chance to contain an invasive cancer than smaller ones.[3]
- With Contrast-enhanced ultrasonography gallbladder cancer shows an “eruption sign”[4]
