Abstract
The purpose of this report is to describe the magnetic resonance (MR) imaging characteristics
of low-flow vascular malformations of the face. We studied six patients ranging in
age from 1 month to 20 years old, with surgically proven or clinically certain low-flow
vascular malformations of the face. T1-weighted MR images of five lesions showed homogeneous
intermediate to low signal intensity, similar to the signal intensity of muscle. T1-weighted
images of one lesion showed mild high signal intensity and image of another demonstrated
fatty infiltration. After contrast administration, images of four lesions showed moderate
to marked enhancement, three diffused and one patchy. On T2-weighted sequences, five
lesions were heterogeneously of high signal and one of low signal intensity. Three
lesions exhibited low-signal septa, and two revealed low-signal vascular flow voids
on both types of sequences. Satellite nodules were present in three instances. Low-flow
vascular malformations involving the face in children and young adults have a heterogeneous
and nonspecific appearance on MR images. They should be considered in the differential
diagnosis of all facial masses presenting in children and young adults. Enhancement
with contrast material is essential to localize the mass.
