Hypervascular liver lesions

Last revised by Yahya Baba on 21 Oct 2021

Hypervascular liver lesions are findings that enhance more or similarly to the background hepatic parenchyma in the late arterial phase, on contrast-enhanced CT or MRI.

Differential diagnosis

Primary lesions
Metastases

Although the majority of liver metastases are hypodense and enhance less than the surrounding liver, metastases from certain primaries demonstrate an increase in the number of vessels, resulting in a hyperechoic ultrasound appearance, and arterial phase hyperenhancement on CT or MRI which washes out on delayed scan (cf. hemangioma which does not show washout). The primaries typically include:

Other secondary lesions
