PINEAL PARENCHYMAL TUMOR OF INTERMEDIATE DIFFERENTIATION-A CASE REPORT

Abstract

Pineal parenchymal tumours are uncommon, accounting for less than 0.3% of all primary CNS tumours. Pineal parenchymal tumours are diverse entities with a wide range of morphology. These tumours are histologically subdivided into pineocytoma (grade I), pineoblastoma (grade IV), papillary tumour of the pineal region (grade II or III), and pineal parenchymal tumour of intermediate differentiation (PPTID) (grade II or III) according to the WHO classification for tumours of the central nervous system (2021 revision). PPTID is an illness that has only recently been identified. Here, we report a case of pineal parenchyma tumor of intermediate
differentiation. An adult female diagnosed with PPTID after surgery and treated with adjuvant EBRT alone to 54Gy in 30 fractions using shrinking field technique with CSI in initial phase. No other adjuvant treatment received.
