An abdominal ultrasound was performed, showing a voluminous multiseptated cystic mass in the liver, with no detected flow on color doppler mode (Figure 1).
Axial post-contrast CT image of the abdomen, showing the mesenchymal hamartoma (Orange arrows) of the liver. A hyper-enhancing nodule was seen within (Blue arrow). Spared segments II and VI of the liver can be seen (Asterisk).

A chest-abdomen-pelvis computed tomography (CT) was performed subsequently, showing a multicystic well-defined hepatic mass with regular contours, a thick wall, containing fluid and thick enhanced septas with a hyper-enhanced nodule within, occupying segments VIII, V and IV of the liver (Figure 2).
Images of liver mass: intraoperative (A), and after resection (B).

It involved a complete resection of the encapsulated mass, as well as a retrograde cholecystectomy due to the gallbladder's adherence to the mass (Figure 3).
Histopathologic examination images (A and B) (Routine stain, 40X magnification), showing a mixture of bile ducts, hepatocyte trabeculae, and congestive vessels on a hemorrhagic fibrous background.
