[Von Meyenburg Complexes or Biliary Hamartomas: A Case Report].

INTRODUCTION

. Von Meyenburg complexes or biliary hamartomas are a rare benign congenital anomaly of the intrahepatic bile ducts. They are usually asymptomatic and incidentally found on imaging studies but can cause jaundice, abdominal pain, and cholangitis.

CASE REPORT: . An 80-year-old male patient was admitted to the emergency department due to progressive jaundice associated with pruritus, with an altered hepatogram and a cholestasis pattern. Imaging studies were performed in which there were no alterations in the liver parenchyma or bile ducts. A liver biopsy was performed, which revealed perivenular canalicular cholestasis and the presence of von Meyenburg complexes. The patient was treated with ursodeoxycholic acid with normalization of cholestasis at outpatient follow-up.

CONCLUSION

. The diagnosis of biliary hamartomas should be considered in patients with intrahepatic cholestasis in whom the etiology is not identified by initial studies. They represent a diagnostic challenge as they are not always seen in imaging studies.
