Agenesis of the left hepatic lobe

Case contributed by Dr Nasr Timol


Incidental finding in a patient undergoing CTPA for suspected pulmonary embolus. No prior history of hepatectomy.

Patient Data

Age: 45 years
Gender: Female


The left hepatic lobe is largely absent with a small amount of remnant tissue noted adjacent to the falciform ligament.

The left hepatic artery is not identified.

The left portal vein is also not appreciated (despite scan not being the portal venous phase).

The right hepatic lobe and caudate lobe demonstrate mild compensatory hypertrophy.

Case Discussion

Incidental finding.

Absence of left hepatic vascular structures confirms developmental anomaly rather than atrophy of the left lobe.
