title: [Acute psychiatric pathology disclosing subcortical lesion in neuro-AIDS].
abstract: Maccario et al. described, in 1987, the case of an HIV-positive patient whose psychotic symptomatology was the expression of right centrum semi-ovale lesion. We report the case of a patient who suffered a sudden delirium, expression of a probable right lenticular cerebral toxoplasmosis. This 35-year-old male homosexual, who had no psychiatric history, suddenly developed in November 1988 the following psychiatric signs: he started to walk back and forth incessantly, he had the impression that he was the subject of the conversations of the passers-by, that all the posters and notices refer to him, and that he was God. He was admitted in a psychiatric department where the symptoms were progressively curbed by neuroleptics (cyamemazine 75 mg, and haloperidol 15 mg). The episode was not questioned by the patient, but attributed to bad eating habits. HIV-positivity had been discovered a year later (during systematic screening). A computerized tomographic (CT) scan performed subsequently to this delirium was interpreted as normal. Four weeks later the patient was referred to us. The psychiatric condition was stabilized in spite of a certain aggressiveness and the probable persistence of an underlying delirium state. Laboratory examinations showed the following: blood count revealed leukopenia (2.2 G/l) and thrombocytopenia (135 G/l; OKT4/OKT8 ratio was 0.08; CSF: normal; sputum culture evidenced the presence of pneumocystis carinii; EEG were normal. Neuropsychological symptoms concerned in particular a lack of concentration during the different tests with a definitive wavering of attention. Lexical retrieval was poor whatever the topic proposed.(ABSTRACT TRUNCATED AT 250 WORDS)
