Gallbladder Polyps Coexisting with Adenomyomatosis Clinical History A 48-year old lady presented with a long-term history of right upper quadrant abdominal pain. The patient was referred to have an ultrasound of the abdomen to check for possible gallbladder calculi (gallstones). Case Description An abdominal ultrasound was performed using a 6 MHz curvilinear transducer. Ultrasound revealed multiple tiny gallbladder polyps. The largest polyp measured up to 4 mm x 4 mm in length and AP diameter. The gallbladder was thin-walled and contained no calculus within its lumen. However, there were multiple gas pockets within the gallbladder wall that appeared as ‘comet tail’ artefacts in keeping with Rokintansky Aschoff sinuses. These ultrasound appearances of the gallbladder have been known to be related to gallbladder adenomyomatosis. Diagnosis/ Discussion/ Treatment/ Follow up The patient was placed on an ultrasound pathway where the gallbladder would be monitored every six months to check for any abrupt change in appearances.
