Distal cholangiocarcinoma Aug 27, 2005
Small hypoechoic mass (10/8 mm) visualized in the terminal part of the common bile duct, with thickening of the walls and loss of the normal wall structure. As brush cytology during a previous ERCP was negative for malignancy, the diagnosis was confirmed by EUS-guided FNA. ERCP showed a tight stricture in the terminal part of the CBD, with subsequent dilatation of intra and extrahepatic ducts. A 12 Fr. stent was consequently inserted.

Small distal cholangiocarcinoma Feb 8, 2005
Small distal cholangiocarcinoma visualized on EUS as a hypoechoic tumor, in the intrapancreatic terminal part of the CBD, surrounding the stent inserted during previous ERCP. EUS-FNA was negative for atypical cells; however, brush cytology from the bile duct was positive, and the patient was referred for radical duodeno-pancreatectomy.
