US of the liver, oblique B-Mode imaging and colour-Doppler study at birth (upper line), at 1 month (central line) and at 3 months (lower line): there is a large heterogeneous mass, measuring about 20 mm, mostly iso-hypo-echoic, with internal anechoic tubular structures. Colour-Doppler images shows internal vessels characterised by both arterial and venous flow. At follow-up, B-mode evaluation shows slight reduction of diameter with increase of the internal anechoic necrotic component. Moreover, colour-Doppler tool demonstrates significant reduction and finally disappearing of internal vascular flow. These features were in keeping with the diagnosis of focal hepatic haemangioma
