Abstract

Pineal parenchymal tumours (PPTs) represent one third of the pineal region tumours. PPTs are subdivided
into pineocytoma (PC), pineoblastoma (PB) and PPT with intermediate differentiation (PPTID). We report
radiological, morphological and immunochemical features which permit to grade these tumours. Tumors of
the pineal region can arise from multiple cellular origins and thus represent a very heterogeneous group of
pathologies.Within the subgroup of pineal parenchymal tumors, there is a histopathologic spectrum ranging
from pineocytoma to pineal parenchymal tumors of intermediate differentiation to pineoblastoma. The
currentWorld Health Organization classification and the histopathologic features of the pineal parenchymal
tumor subtypes with intermediate differentiation are described.

Keywords: Pineal parenchymal tumours, Pineal parenchymal tumours with, Intermediate differentiation, Pineoblastoma and Pineocytoma.
