ACUTE CALCULOUS CHOLECYSTITIS
Stones or concretions frequently occur in the gall bladder. Stones
occur about twice as frequently in women as in men. The majority of stones are cholesterol
stones, and less than 10% are pigment stones. Ultrasonography is the primary imaging
modality for diagnosing gall stones and gall bladder disease. A stone is seen as a
rounded, echodense (white) structure with a typical acoustic shadow behind it. USG
findings in acute cholecystitis include thickening of the gall bladder wall (greater than
3 mm), the sonographic Murphys sign, sludge and pericholecystic collection. In
chronic cholecystitis, collapsed gall bladder and thickened or calcified gall bladder wall
are noted. |
