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