Primary Brain Lymphoma

The broad spectrum of C.T. findings in a group of 15 patients with primary brain lymphoma are reviewed. An attempt has been made to emphasize the more typical lesion characteristics, including location, definition, multiplicity and attenuation, both prior to and following contrast administration. Clinical presentation, changing C.T. appearances following radiotherapy and ultimate prognosis are briefly described. Differential diagnoses and their significance for management are discussed.
