Figure 1. (a) Axial T₁ weighted (repetition time (TR) 450/echo time (TE) 14) image of the orbits shows a complex mass in the left orbit. Anterior component is isointense to muscle. Posterior cystic component is well defined homogeneous, low signal intensity similar to vitreous/cerebrospinal fluid (CSF). (b) Axial T₂ weighted (TR 3000/TE 95) image of the orbits shows the soft tissue component to be heterogeneously hyperintense. The cyst appears brightly hyperintense with smooth thin walls. No normal orbital contents such as extraocular muscles or globe can be identified. (c) Axial post-gadolinium fat saturated T₁ weighted image shows heterogeneous enhancement of the anterior soft tissue mass. Enhancement is much more than brain parenchyma.
