BSGAR RCR Gallbladder Workshop: Polyps and Cancer

This playlist has been created from material presented by Drs Helen Bungay, Jamie Franklin, Appu Rudralingam and Ed Godfrey at the BSGAR Gallbladder Workshop at the Royal College of Radiologists Annual Scientific Meeting 2016. 

This playlist presents a series of cases which address some of the key imaging considerations related to the diagnosis and management of suspected GB polyps and cancer. 

 

 

Learning points:

1. Gallbladder polyps 10 mm or larger, or those in patients with PSC should be discussed in the HPB MDT for consideration of cholecystectomy. Follow up of smaller polyps is controversial. 

2. Benign gallbladder conditions such as adenomyomatosis often have pathognomonic imaging features and can be confidently dismissed.

3. Gallbladder cancer manifests as a gallbladder mass and is usually associated with gallstones. It may be advanced at presentation. Common sites for metastases include the liver, peritoneum and umbilicus. 

4. Porcelain gallbladder, whilst previously thought to be a premalignant condition, is no longer thought to warrant cholecystectomy nor imaging follow up.

5. Xanthogranulomatous cholecystitis is a rare condition, 10 times less common than gallbladder cancer. It is a process centred on the gallbladder wall, with mural low attenuation/cystic spaces and preservation of the mucosa.
