a Brain, basal ganglia. Granulomatous inflammation characterized by macrophages, lymphocytes, eosinophils, multinucleated giant cells and many gitter cells. (hematoxylin-eosin staining). Scale-bar: 40 μm. Inset: Embryonated egg (hematoxylin-eosin staining). Scale-bar: 10 μm. b Low magnificaton of cholesterol granuloma. Cholesterol clefts are surrounded by vascular proliferation with hypertrophic walls and scattered foam cells. Fragments of ependymal epithelium are visible (hematoxylin-eosin staining). Scale-bars: 300 μm
