Pineal region tumours (PRT) are rare, accounting for less than 1% of all Central Nervous System (CNS) neoplasms1. Several distinct tumour types can occur in this location, reflecting the heterogeneity of the various structures of this small region. Pineal parenchymal tumours (PPT) represent approximately 27% of PRT and they are thought to be derived from pineocytes [1], cells with photosensory and neuroendocrine functions associated with melatonin production. According to the World Health Organization (WHO) 2016 classification of CNS tumours, PPT can be divided into three distinct tumour types, that differ in the degree of differentiation and biological behaviour: pineocytomas, pineal parenchymal tumours of intermediate differentiation (PPTID) and pineoblastomas [1].
