[Toxoplasma encephalitis with atypical manifestation and normal CT].

A case of cerebral toxoplasmosis in a HIV-positive man with unusual clinical manifestations and a normal computed tomographic (CT) scanning is presented. Even though most patients with cerebral toxoplasmosis have focal neurological deficits on physical examination, the patients can also present with more diffuse symptoms. Neither the lack of antitoxoplasma antibodies nor normal findings at CT scanning exclude the diagnosis of toxoplasma encephalitis. The sensitivity is higher with magnetic resonance than with CT scanning. We present a case story that demonstrate how delusive cerebral toxoplasmosis can be in HIV positive patients. It is recommended that the possibility of cerebral toxoplasmosis be considered in every HIV-positive patient with neurological symptoms and empirical therapy be instituted on wide indications.
