The left optic nerve is entrapped by the homogeneous, slightly hyperintense on T2WI tissue, which strongly enhances on T1+C fat saturated series. The globe, extraocular muscles, lacrimal gland and retrobulbar tissue are normal.
Case Discussion
The enhanced tumor surrounds the nonenhanced left optic nerve and results in Tram-track sign (orbit) on the axial images.
