case_images: Initial imaging - Axial and coronal contrast-enhanced computed tomography of the abdomen (portal venous phase) demonstrates a large, complex mass lesion in the right abdomen. It abuts the inferior liver border with a poor plane of separation and displaces the bowel to the left (arrowheads). There is a lack of peripheral hepatic parenchymal extension along the edges of the mass (claw sign); therefore, hepatic origin cannot confidently be suggested. Solid and cystic elements are clearly distinguishable (arrow) with the classic 'swiss cheese appearance'.

case_images: Contrast-enhanced abdominal computed tomography (CT) in the portal venous phase demonstrated a large, well-demarcated intraperitoneal mass (Figure 1), measuring approximately 17 cm x 16 cm x 15 cm.
case_images: Follow-up imaging - Abdominal computed tomography scout image and coronal contrast-enhanced imaging (portal venous phase) demonstrates the mass to have shifted into the left abdomen (arrow), causing displacement of the bowel to the right (arrowheads). This reveals the mass to be mobile and separable from the right and left liver lobes.

case_images: It revealed the mass to have shifted into the left-sided abdomen, completely separable from the right and left liver lobes, with displacement of the bowel to the right (Figure 2).
case_images: Follow-up imaging - Axial contrast-enhanced computed tomography of the abdomen (portal venous phase) shows the mass within the left upper abdomen. A thin pedicle is seen connecting the mass to the caudate lobe of the liver (arrowheads). This confirms a pedunculated mass of hepatic origin.

case_images: A thin pedicle could now be identified connecting the mass to the caudate lobe of the liver (Figure 3).
