MRI AND CT DIAGNOSTICS IN ACUTE CEREBRAL TUBERCULOSIS

5 unusual cases of cerebral tuberculosis are reported. Three of the ca ses initially showed the typical history and aspect of herpes simplex encephalitis, and two of a cerebral tumour. Both CT and MRI, and also the clinical neurological symptoms, were confusing. Microbiological cu lture in three and histological preparation in two cases confirmed the diagnosis of cerebral tuberculosis. Three cases showed the developmen t of tuberculomas under therapy. The study of the literature suggests that this is not rare, which is explained by pathogenetic reflexions c oncerning the allergical genesis of the tuberculomas.
