CHAPTER 52  ORBITAL TUMORS  415

KEY POINTS

•Unilateral or bilateral proptosis usually requires imaging, especially if it is progressive.

•CT of the orbit is generally easier to obtain and interpret than MRI.

•CT is the recommended imaging modality for trauma, infection, and thyroid eye disease (Graves’ orbitopathy).

•MRI is recommended for soft tissue processes, for imaging of the orbital apex/cavernous sinus, and for suspected intracranial processes.

•Orbital lymphoid hyperplasia requires systemic monitoring identical to orbital lymphoma.

•Well-tolerated, well-circumscribed lesions of the orbit can be followed conservatively with serial imaging alone in selected cases.
