title: Computed tomographic evaluation of metatases to the orbit.
abstract: The computed tomographic (CT) findings in 22 patients with metastases to the orbit were evaluated. All the metastases appeared to be unilateral on CT. Sixty-eight percent of the patients showed evidence of aggressive adjacent bone destruction. Sixty-eight percent of the patients had intracranial metastatic disease, 46% had direct intracranial extension of the tumor, and 23% had CT evidence of separate intracranial metastases. Fifty-nine percent of the orbital metastases were extraconal, 19% were intraconal, and 19% were both intraconal and extraconal; one case of metastases to the globe was detected. All 13 patients examined before and after contrast showed evidence of enhancement.
