(a) A 10-week-old female infant. Note multiple segmental facial red haemangiomas, the ulceration on the bottom lip, and the sub-
cutaneous haemangioma of the left upper medial eyelid that causes swelling and partial obscuring of the left eye. (b) Same patient after 9
months on propranolol. Note the degree of involution of the lesions shown in c. (c) Another patient, a 6 month-old female, with a palpable soft
mass in the left lateral neck, an IH. Axial T2-weighted image with fat saturation demonstrates a well-de
fi
ned, hyperintense soft-tissue mass in
the left neck with few internal serpiginous
fl
ow voids. (d) Contrast-enhanced T1-weighted image with fat saturation demonstrates avid, ho-
mogeneous internal contrast enhancement of the solid vascular mass. (e
e
f) Time-resolved DCE-MRA in the arterial phase demonstrate that the
avid homogenous enhancement of the IH starts in the arterial phase (note that only the arteries are enhanced, no veins visualized) from a
feeding artery taking off from the left external carotid artery (arrow). Serpiginous
fl
ow voids noted in c were demonstrated to represent the
feeding arteries and draining veins of the IH. Note the draining vein into the left subclavian/IJ junction (arrow) (f).
