Case of the Week 52

Brain biopsy from an adult male with mental status changes. The 2 images are from the same microscopic field at different planes of focus, to demonstrate the range of findings. Identification? (CLICK ON IMAGES TO ENLARGE)

Toxo for sure. The cyst in the central field is a tachyzoite right?

Toxo (maybe I should have suggested brain biopsies in my psych job I did last!)
