A Transversal brain section showing a 2.0 × 2.0 × 2.5 cm in size measuring mass (♦), almost completely filling the dilated lateral ventricles with disruption of the interventricular septum and compression of the adjacent parenchyma (➔). B Histopathology of the ventricular mass revealed a granulomatous inflammation with high numbers of foamy, hemosiderin-laden macrophages (O, > in insert) in the choroid plexus with numerous, optically empty “cholesterol clefts” (*), separated by fibrous septae (➔), bars represent 200 µm in the overview, 20 µm in the Prussian blue staining (top right) and the HE (bottom middle) as well as 40 µm in the Azan (bottom right)
