a MRI (4 months post-liver resection): focal lesion at segment II/III of the liver measuring 2.5 cm in diameter, with signal intensity and enhancement pattern impressive of metastasis. b PET scan 4 months post-liver resection: intense uptake in the left lateral aspect of the left liver lobe (segment II/III) corresponding to an approximately 2 cm sized hypodense lesion. New intense uptake corresponding to hypodense lesion in the left liver lobe consistent with new liver metastasis
