Preschooler with a right orbital mass

MR of orbital myofibroma
Coronal T1 MRI without contrast of the orbits (left) and coronal T2 MRI (middle) shows a round soft tissue mass superior and lateral to the right orbit that is isointense on both sequences and that on coronal T1 MRI with contrast (right) is seen to enhance uniformly and intensely.

The diagnosis was myofibroma.
