Revisiting the metastatic potential of childhood pineal parenchymal tumor of intermediate differentiation: a case report
Pineal parenchymal tumor of intermediate differentiation (PPTID) is a rare entity, the biological behavior of which is largely unknown due to few reported cases overall and diagnostic pitfalls in the small sample [1, 2]. The extent of surgery as well as the role of adjuvant chemoradiotherapy in PPTID is still contentious. Dissemination into spinal axis, a known phenomenon for childhood pineoblastoma (PB), has been reported rarely in PPTID [2, 3, 4] and embarks upon redefining the treatment paradigms for these tumors. Simultaneous intracranial as well as spinal dissemination at presentation in childhood PPTID is a rarity indeed and provides new insights to the varied biology of this potentially malignant tumor.
