CT scanning in epidural lymphoma

This study describes the clinical features and CT findings in 18 patients with epidural lymphoma seen in a large oncology hospital over a four-year period. The variety of CT appearances seen in epidural lymphoma are illustrated. The importance of recognition of small volume epidural disease on body CT is stressed. Patients with apparently minor CT abnormalities may have significant epidural disease. The prognosis for these patients with minimal symptoms and small volume disease is much better than for those with classical signs of cord compression and more obvious abnormalities on imaging.
