FIG 1. Images from the case of a 3-year-old female patient with a suspected vascular abnormality of the scalp.
A, Unenhanced sagittal T1-weighted MR image shows an extra-calvarial soft tissue mass.
B, Marked uniform enhancement can be seen after the administration of contrast material. Serpiginous flow void represents an enlarged feeding vessel.
C, Selected MR digital subtraction angiograms show prominent filling of contrast material in the arterial phase and prominent enhancement of the lesion. This was considered to represent a high-flow lesion.
