A Pitfall in the Diagnosis of Unresectable Liver Metastases: Multiple Bile Duct Hamartomas (von Meyenburg Complexes)
نویسندگان
چکیده
Von Meyenburg complexes (VMC) are a cluster of benign liver malformations including biliary cystic lesions, with congenital fibrocollagenous stroma. This rare entity can mimick multiple secondary hepatic lesions. We report a case of a 56-year-old woman who had multiples liver lesions 12 years after operation for breast cancer. Biopsy of the hepatic lesion confirmed the diagnosis of VMC. Preoperative discovery of multiple gray-white nodular lesions scattered on the surface of the liver should not always contraindicate curative liver resection. The diagnosis of VMC should be known and confirmed with liver biopsy.

Magnetic resonance imaging (MRI) demonstrated multiple highly intense, regular nodules (less than 15 mm) with no communication to the bile tree (Fig. 1A). After intravenous gadolinium DTPA, some nodules showed peripheral enhancement from hepatic ...

An obese 54 year old female patient with a BMI of 43kg/m2 was scheduled to undergo diagnostic laparoscopy and laparoscopic gastric bypass operation. At laparoscopy both liver lobes showed widespread small lesions involving all surface of liver, suggestive of metastatic malignant disease. Liver was normal in shape with multiple intricate white to pale yellow nodular spots of average diameter 0.3...
متن کاملRare liver tumor: symptomatic giant von Meyenburg complex
von Meyenburg complexes are hamartomas that arise from intra-hepatic bile ducts. Symptomatic lesions are uncommon and giant lesions are exceedingly rare. When encountered, they should be excised because there are reports of malignant change in large, symptomatic lesions. We report a case of a symptomatic giant von Meyenburg complex.

متن کاملComputed Tomography and Magnetic Resonance Imaging Findings in a Case with Biliary Microhamartomas
Biliary microhamartomas, also known as bile duct hamartomas and von Meyenburg complexes, are benign neoplasms containing cystic dilated bile ducts embedded in fibrous stroma. They develop in hepatobiliary system, do not generally give clinical outcomes, and are detected incidentally. However, they can rarely show malignant transformation. Our aim was to report the contribution of computed tomog...
