Characterization of focal liver lesions in non-cirrhotic liver
Table 5. Demographic characteristics and indications for biopsy in 58 histological proven haemangiomas.
Characteristics
Demography
no (M/f) 58 (29/29)
Mean age (year)
indication for biopsy
56 ± 13 [24 – 77]
Underlying malignant disease 41/58 (81%)
growing tumour* 2/58 (3%)
(suspected) liver cirrhosis (HcV/PBc/cf*) 15/58 (19%) (10/4/1)
m = male, f = female, HcV = hepatitis-c-virus infection, PBc = primary biliary cirrhosis, cf = cystic fibrosis
*an impressive growth pattern from less than 20 mm to more than 50 mm within 2 years was seen in a patient with a malignant
ovarian tumour.

Figure 2. Giant haemangioma. a)
B-mode. b) Arterial phase – typical
nodular, peripheral enhancement. c)
Portal phase – progressing fill-in of the
enhancement. d) Late phase progressing
fill-in, most of the lesion is enhanced.
e) Late phase – almost whole
lesion is enhanced, non-enhanced parts
are depicting thrombosis or fibrosis.
*representing the colour Doppler imaging (cDi) sign of peripheral nodular contrast enhancement in patients with liver cirrhosis
the tumours were hyperechoic in 14 and isoechoic in 1. in none of the patients cDi was helpful in identifying shunts since
perfusion patterns can not be displayed.
