Contrast enhancement in 95 patients with histologically proven benign liver tumours or lesions
| Liver tumour | Isoechoic contrast enhancement |
|---|---|
| *The vascular phase contrast enhancement pattern of haemangiomas was variable. Characteristic was a progressive heterogeneous centripetal fill in and considerable enhancement on liver specific late phase imaging, revealing diminished contrast to the surrounding liver parenchyma in all patients. | |
| Benign liver lesions (n = 95) | 88/95 |
| Focal nodular hyperplasia (n = 36) | 35/36 |
| Haemangioma (n = 31) | 31/31* |
| Adenoma (n = 10) | 10/10 |
| Abscess (n = 5) | 0/5 |
| Microhamartomas (n = 4) | 4/4 |
| Focal steatosis (n = 4) | 4/4 |
| Focal biliary cirrhosis (n = 1) | 1/1 |
| Bacillary angiomatosis (n = 1) | 1/1 |
| Nodular regenerative hyperplasia (n = 1) | 1/1 |
| Regenerative nodule (n = 1) | 1/1 |
| Inflammatory pseudotumour (n = 1) | 0/1 |
