The prognostic importance of CT features in primary intracranial lymphoma

Abstract

The correlation of computerized tomography (CT) features with survival of 28 patients with primary intracranial lymphoma was analysed retrospectively. Severe perifocal oedema, periventricular tumours and lesions which were non-homogenously enhancing or non-enhancing were found to be associated with a poor prognosis. The prognosis when multiple lesions were present was almost the same as that of a solitary lesion (p = 0.95). Ring enhancing lesions had considerably longer survival. Lesions in the frontal region and those close to the meninges, enhancing homogeneously, had a better prognosis.
