Case History: 7-year-old patient with history of proptosis on the right side and temporal swelling.

The morphology is variable, ranging from well-defined rounded lesions to diffusely infiltrating lesions.
MRI appearances are similar to CT, but the greater contrast resolution of MRI makes it invaluable in the assessment of orbital masses.
Orbital metastasesÂ are relatively uncommon, but some primary tumors do have a predilection to metastasize to theÂ orbit.
UnlikeÂ primary orbital tumors,Â which most frequently present with proptosis and/or visual loss, orbital metastases most commonly present with diplopia.
Unfortunately, the discovery of orbital metastases usually indicates advanced and widespread metastatic disease and prognosis is dismal.
Differential diagnoses include primary orbital malignancy and extraocular extension of intraocular tumor.
