Abstract

---

Background: Mature teratomas are common tumors in the pediatric population. They can arise in the central nervous system and often require surgical resection. They are classified as non-germinomatous germ cell tumors and their recurrence are extremely rare. Case Presentation: We are reporting the case of a 6-year-old boy who was diagnosed with mature pineal teratoma after he presented with signs of acute hydrocephalus. Histopathology did not reveal any other germ cell tumor component. He underwent a complete resection of the mass, with no adjuvant chemotherapy. Nine years post-operatively, magnetic resonance imaging results showed recurrence of the pineal tumor as a germinoma. Chemotherapy and radiotherapy resulted in significant shrinkage of the mass and resolution of the clinical symptoms. Conclusion: This case illustrates the possibility of the late recurrence of a germinoma after the complete removal of a mature intracranial teratoma. It also raises the issue of whether mature teratomas should be treated with adjuvant therapy after surgical resection to prevent their recurrence as another germ cell tumor.
