Gallbladder ghost triad

Last revised by Daniel J Bell on 8 Feb 2021

Gallbladder ghost triad is a term used on ultrasound studies when there is a combination of three gallbladder features on biliary atresia:

  • atretic gallbladder, length less than 19 mm
  • irregular or lobular contour 
  • lack of smooth/complete echogenic mucosal lining with an indistinct wall

The term gallbladder ghost was coined in 2003 by a Singaporean radiologist Anne Poh Ann Tan Kendrick (fl. 2019) because the gallbladder is so small and difficult to see in biliary atresia, like a ghost 1.
