H&E stained sections demonstrating the degenerate parasite after initial craniotomy. (a) The entire tissue is a complex of cysts, with no viable basophilic nuclei apparent at low power, including no inflammatory cells (original magnification 12.5x). (b) At higher magnification, the edge of the abnormal tissue has the typical appearance of a chitinous exoskeleton with a few surviving small nuclei beneath it (original magnification 400x).
