Misleading appearance of biliary dilatation.
Dilated biliary radicles demonstrated on 99mTc-dimethyl-acetanilide-imino-diacetic-acid (99mTc-IDA) imaging suggested biliary obstruction, and led to transhepatic cholangiography and endoscopic retrograde cholangiopancreatography. Both showed a biliary tree of normal diameter.
