Agenesis of the right hepatic lobe
Agenesis of the right hepatic lobe is a rare variation in liver anatomy.
Radiographic features
- absence of the right hepatic lobe
- absence of right hepatic artery, right portal vein, and right hepatic biliary system
- compensatory hypertrophy of the left hepatic lobe and caudate lobe
- possible retrohepatic gallbladder
Differential diagnosis
- hepatectomy (look for postsurgical change)
- severe hypoplasia/atrophy of the right hepatic lobe: right lobe structures will still be present
