title: Nervous system manifestations and neuroradiologic findings in acquired immunodeficiency syndrome (AIDS).
abstract: We report a series of thirteen patients with nervous system complications out of a total of thirty AIDS patients admitted to our hospital over the last two years for which CT and/or MRI have been performed. Five were homosexual men and eight patients (5 men, 3 women) were of African origin (Zaïre and Rwanda) (n = 5) or had had sexual intercourse with the local African population (n = 3). The nervous system complications encountered included: toxoplasma gondii brain abscess (2 patients); cryptococcus neoformans meningitis + toxoplasmosis (1 patient); toxoplasmosis + lymphoma (2 patients); progressive multifocal leucoencephalopathy (1 patient); lymphocytic meningitis or encephalitis (3 patients); lymphoma (1 patient); polyradiculoneuritis (3 patients). Three of thirteen patients had multiple intracranial abnormalities: one had concomitant intraparenchymal toxoplasma abscess and cryptococcal meningitis; in one patient a lymphoma developed after the successful medical treatment of a toxoplasma abscess; conversely, one patient developed a toxoplasma abscess two years after mediastinal radiotherapy for a systemic non-Hodgkin lymphoma. In conclusion, in our experience, nervous system toxoplasmosis is the most frequent AIDS related CNS complication. Our series demonstrates the high frequency of a second neurological disease occurring either concomitantly or separately. In these cases, while CT may readily identify the intracranial abnormalities, it contributes little towards an etiological diagnosis. Finally, our series illustrates the importance of a central African endemic focus for AIDS.
