title: Foraminal expansion by malignant retroorbital lymphoma: CT findings.
abstract: A 43-year-old man presented with an orbital mass and cranial nerve dysfunction resulting from malignant lymphoma. Computed tomography showed prominent widening of bony foramina by the orbital and middle fossa tumor and an up to now unreported presentation of this lesion. Bony erosion, a distinctly atypical, although reported, feature of lymphoma suggesting malignancy, was also present. Implications for radiologic diagnosis are discussed.
