Von Meyenburg complex

The Von Meyenburg complex is a form of hepatic hamartoma. They are found in the periportal zone.^[1]

It is named for Hans von Meyenburg.^[2][3]

The Imaging findings are

• Biliary hamartomas are typically multiple round or irregular focal lesions of nearly uniform size (up to 15 mm) scattered throughout the liver.
• CT:Biliary hamartomas are hypoattenuating at CT
• MRI:Biliary hamartomas are hypointense at T1-weighted MR imaging and hyperintense at T2-weighted imaging. If the echo time is increased at T2-weighted imaging, the signal intensity of these lesions increases further and approaches that of cerebrospinal fluid. Biliary hamartomas do not usually show contrast enhancement, although a peripheral enhancing rim has been described. This has been hypothesized as related to compressed surrounding normal liver parenchyma
