Brainstem involvement by Toxoplasma gondii is probably more common than
other opportunistic infections, although it has not received adequate
attention. Identification of toxoplasmosis is essential, as this
condition responds to treatment with a significant increase in life
expectancy. During the past 4 years, 366 AIDS patients with central
nervous system toxoplasmosis diagnosed by biopsy or improvement
following empirical treatment were evaluated. Among them, 8 (7 men, 1
woman; aged 25-55 yr) presented with signs of brainstem dysfunction. Six
patients presented with an oculomotor nerve palsy and contralateral
hemiplegia; 1 had an additional ipsilateral rubral tremor. The seventh
patient had complete external ophthalmoplegia and the eighth had
Parinaud's syndrome. Computed tomography revealed enhancing lesions in
the brainstem of all patients. Seven responded to treatment with
pyrimethamine and sulfadiazine.
