Figure 1: Patient 1. (a) T1 sagittal and (b) T2 axial MR images showing iso- to hyperintense, intraventricular lesion with moderate hydrocephalus. (c) Endosopic biopsy from the tumor (arrow). (d) H and E stained section (×400) showing sheets of small cells displaying round to oval hyperchromatic nuclei and scant cytoplasm with few fibrillary areas. Mitosis is seen. Occasional formation of rosettes is also noted. Calcification is prominent. The findings are suggestive of a pineoblastoma
