title: Lymphoma presenting as a periorbital tumor.
abstract: Lymphoma is a common tumor of the periorbital region. Facial radiographs may show a soft tissue mass. Radiologic differential diagnosis of orbital masses is difficult. Computed tomographic scanning with intravenous contrast medium is useful in diagnosing and staging neoplasms in this area.
