case_images: Abdominal radiographs of a 2-year-old female Shih tzu dog. (A): Ventral-dorsal radiograph reveals that gastric silhouette is displaced toward the left abdominal wall. (B): lateral radiograph reveals gastric silhouette parallel with the diaphragm outline.

case_images: An abdominal radiograph revealed that gastric silhouette was parallel with the diaphragm outline (Fig. 1).
case_images: Transverse computed tomography images of a two-year-old female Shih tzu dog before surgical treatment. (A): Dorsal-ventral abdominal radiograph. Three lines reveal each transverse section level. Transverse computed tomography images at levels of (B) the tenth, (C) the eleventh and (D) the twelfth thoracic vertebrae in the portal phase revealed an enlarged bile duct (large arrow: blue) and gallbladder (arrowhead: red) and a shunt vessel (small arrow: yellow) between the caudal vena cava and left gastric vein. No left liver parenchyma was observed at any transverse section levels.

case_images: No portal and hepatic veins of these lobes were observed during the portal and equilibrium phases (Figs. 2 and 3).
case_images: Computed tomography multiplanar reconstruction (MPR) images of a two-year-old female Shih tzu dog before surgical treatment. (A): Sagittal MPR image. Three lines reveal each dorsal section level. (B-D): Dorsal MPR images reveal that the greater part of the left diaphragm is attached to the stomach and the remaining liver exists only on the right side of the gallbladder. Large arrow (blue) shows spleen, small arrow (yellow) shows pancreas, large arrowhead (red) showed bile duct and small arrowhead (red) shows the gallbladder. No left liver parenchyma was observed at any dorsal section levels.

case_images: No portal and hepatic veins of these lobes were observed during the portal and equilibrium phases (Figs. 2 and 3).
case_images: Portography and three-dimensional computed tomography (3D-CT) images of a two-year-old female Shih tzu dog. (A): Portography after temporary occlusion in the remaining liver. Portal veins of the right medial hepatic lobe (large black arrow), right lateral hepatic lobe (white arrowhead) and caudate process of the caudate lobe (white arrow) were visualized, but no other vessels were observed. Large white arrow shows a gastroduodenal vein. (B): Preoperative 3D-CT image. Preoperative liver volume was 127 cc (18.4 cc/kg). Yellow: abnormal shunt vessel, red: artery, blue: vena cava and purple: portal vein. (C): Postoperative 3D-CT image. Postoperative liver volume was 187 cc (27.1 cc/kg). Gastroduodenal vessels were moved to left after surgery due to liver volume increasing.

case_images: No portal vein branches of the left lobe, quadrate lobe and papillary process of the caudate lobe were visualized under DSA guidance, even after temporary ligation (Fig. 4A). Liver volume two months after surgery was 187 cc (27.1 cc/kg), which showed an increase of 47.2% (Figs. 4B and 4C).
