Computed tomography and magnetic resonance imaging findings in a case with biliary microhamartomas

Alper Dilli et al. Case Rep Med. 2012.

Abstract

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 tomography, routine magnetic resonance imaging, and magnetic resonance cholangiopancreatography in the diagnosis of biliary microhamartomas in a 61-year-old woman.

Ultrasonographic image of liver (L). No prominent lesion could be demonstrated.

Contrast-enhanced CT revealed multiple, scattered, small, hypodense nodular lesions in liver (black arrows).

Figure 3
On T1-weighted image of the liver (a), multiple, small, hypointense nodular lesions with slightly irregular contours (white arrows) are demonstrated, which are hyperintense (b) (white arrows) on T2-weighted image. Diffusion-weighted image (c) reveals no restriction of diffusion in the liver lesions. MRCP (d) depicts an abundant number of hyperintense small lesions allover the liver which show no association with the biliary system. The widths and contours of intrahepatic and extrahepatic bile ducts and pancreatic canal are normal.
