A 36-year-old-male was admitted complaining of headache, right sided weakness and numbness of upper and lower extremity, and multiple cranial nerve deficits. Cranial magnetic resonance imaging revealed an abscess in the pontomesencephalic junction. Patient was then diagnosed to have Human Immunodeficiency Virus with a CD 4 count of 32 cells/ uL, his CSF assay was positive for Toxoplasmosis IgG and was managed as a case of probable brainstem toxoplasmosis. Patient was treated with Co-Trimoxazole 800/160mg 2 tablets twice a day. Upon discharge the patient clinically improved and was tolerating oral feeding. A repeat cranial magnetic resonance imaging after 6 weeks of antibiotic treatment revealed a decrease of size in the previous lesion. To our knowledge, there are no reported cases in the Philippines that shows the documentation of CNS toxoplasmosis in the brainstem. In this paper, a case of CNS toxoplasmosis in the pons of a newly diagnosed HIV patient is presented and how its course led to a good outcome.
