Figure 1.
Radiological and histopathological findings of patient 1 (a–d) and 2 (e–h) tumors: sagittal FLAIR magnetic resonance imaging showing hydrocephalus caused by a large hyperintense falx cerebellar lesion compressing the aqueduct of Sylvius (a). Computerized tomodensitometry scan displaying a well-circumscribed heterogeneous lesion of the right kidney on T1 sequence after injection of gadolinium (arrow) (b), composed of small and poorly differentiated cells (c; HE, × 380 magnification); loss of nuclear INI1 expression specifically observed in the tumor cells with preserved immunostaining in normal endothelial cells (d; × 380 magnification); axial magnetic resonance imaging showed an enhancing large hyperintense cerebellar lesion (e) and a second lesion within the left foramen of Monro on T1 sequence after injection of gadolinium (f); composed of poorly differentiated cells with typical features of rhabdoid cells in a part of them (g; HE, × 380 magnification); loss of the nuclear INI1 expression in the tumor cells (h; × 380 magnification).
