Abstract:
The paper describes thickening of the wall of the common bile duct in acute pyogenic cholangitis demonstrated by ultrasound. The abnormality appears as a hypoechoic stripe lying internal to the echogenic line of the normal common bile duct. The clinical features of acute cholangitis may be atypical and this new sign should be of value in these difficult cases.
