Description

Von Meyenburg described bile duct hamartomas of the liver.


 

The von Meyenburg complex consists a cluster of benign duct-like structures in a fibrous stroma forming a small cystic nodule. A nodule may range from microscopic or up to 1.5 cm in diameter.

 

The number can range from 1 to many.

 

The lesions are often incidental findings. However, multiple lesions may be mistaken for metastatic carcinoma.

 

Complications are rare and may include:

(1) portal hypertension

(2) cholangiocarcinoma
