abstract
- We report an unusual case of biliary obstruction secondary to adenomyoma of the common bile duct. Adenomyomas are benign tumors, found infrequently in the biliary tree. Clinical presentation, biochemical, radiographic, and endoscopic investigations do not distinguish adenomyomas from malignant or other lesions; diagnosis requires histological examination. The natural history and optimal treatment of these tumors have not been established.
