title: Intracerebral mass lesions in patients affected by AIDS.
abstract: "Toxoplasma gondii" cerebral abscess is a common opportunistic infection in patients affected by AIDS. Making a reliable diagnosis of acute cerebral toxoplasmosis is difficult in AIDS patients because of the lack of specificity of serological data and neuroradiological findings. Brain biopsy is the only procedure which enables a reliable diagnosis to be made a trial of specific medical therapy for toxoplasmosis in patients affected by AIDS and intracranial mass lesion can be advisable before performing brain biopsy. The authors report the cases of three patients affected by AIDS and cerebral toxoplasmosis. Tissue diagnosis was made in the first patient from autopsy material while a presumptive diagnosis was made in the other two cases since specific medical therapy resulted in a dramatic improvement of the neurological status. Despite the good possibilities in the treatment of this complication AIDS, however, carries a poor prognosis.
