title: Use of endoscopic ultrasound for diagnosis of cholangiocarcinoma in auto-immune hepatitis.
abstract: In this report, a patient was exposed to an herbal remedy for hypercholesterolemia. She became acutely jaundiced while taking the remedy and presented for medical care. Endoscopic ultrasound was utilized, and found a distal common bile duct mass. Endoscopic retrograde cholangiopancreatography guided bile duct biopsies revealed that the mass was cholangiocarcinoma (CCA). This case highlights a unique association between autoimmune hepatitis and CCA. It also highlights that EUS can be safely used in patients with cirrhosis to spare invasive evaluation such as exploratory laporotomy for diagnosis and staging of cholangiocarcinoma.
