RADIOLOGY: HEPATOBILIARY: Case# 33656: AIDS CHOLANGITIS. 28 year old HIV positive male with right upper quadrant pain and tenderness. The gallbladder wall is diffusely is thickened without evidence of pericholecystic fluid or stones. No liver masses were identified. Both sclerosing and AIDS Cholangitis can have sonographically identical appearances with smooth or irregularly thickened biliary ducts. Wall thickening may be so marked as to compromise the lumen and lead to the clinical and laboratory findings of obstructive cholangitis. AIDS patients will also present with non-specific and diffuse gallbladder wall thickening, thought to represent infiltration of the HIV virus or other infectious etiologies such as CMV, MAI, or cryptosporidium.
