ABSTRACT

Backround: Pinealoblastomas (PB) are aggressive malignant brain tumors of the pineal region with challenging multimodal management. Objective: The aim of this observation is to highlight the role of a nonsurgical approach especially radiotherapy in the management of PB. The case: We report a case of a young female patient of 17 years old who presented with intra-cranial hypertension. The CT-scan showed a pineal mass with hydrocephalus and the MRI showed a voluminous tumor of the pineal region. The resection was not possible. A Ventriculo-peritoneal shunt was made with tumor a biopsy. The diagnosis of a pinealoblastoma was confirmed on pathology report. The patient received a cranio-spinal radiotherapy with a boost to the tumor and then adjuvant chemotherapy. Results: A complete remission both clinically and radiologically was observed with a follow up of 25 months. Conclusion: Radiotherapy remains a good and safe alternative for surgery in PB.
