GALLBLADDER PATHOLOGY
GALLBLADDER SLUDGE
• Occasionally sludge can be thick and mimic an intraluminal gallbladder mass.
• This is referred to as tumefactive sludge. Mobility of this type of sludge is very important to visualize.
• Tumefactive sludge can form into sludge balls, which will be mobile and will not produce acoustic shadowing.
• Sonographically sludge appears as a collection of low-level non- shadowing dependent echoes within the gallbladder lumen.
