Abstract
The authors present a pediatric case of a pineoblastoma treated with gross-total removal through an occipital interhemispheric transtentorial approach (OITA). The child presented with acute hydrocephalus that was treated by endoscopic third ventriculostomy (ETV) and tumor biopsy through a single burr hole. Histology revealed a pineoblastoma. Microsurgical total removal was performed 3 months after neoadjuvant chemotherapy. OITA was chosen on the basis of the tumor’s location below the Herophilus-Galen line of sight. In this video, the authors show the positioning, the operating devices, the approach, and the microsurgical dissection, indicating all the neurovascular structures encountered.The video can be found here: https://stream.cadmore.media/r10.3171/2021.4.FOCVID2122.

The authors present a pediatric case of a pineoblastoma treated with gross-total removal through an occipital interhemispheric transtentorial approach (OITA)
We describe the occipital interhemispheric transtentorial approach to a pineoblastoma in a 4-year-old child
After identification of the ideal trajectory for endoscopic third ventriculostomy (ETV) joining the tuber cinereum and the center of Monro foramen, and identification of the ideal trajectory for tumor biopsy joining the tumor surface and the center of Monro foramen, we identify an entry point in the middle of the two trajectories allowing both procedures through a single burr hole
Summary
The authors present a pediatric case of a pineoblastoma treated with gross-total removal through an occipital interhemispheric transtentorial approach (OITA). It was decided to treat the hydrocephalus by endoscopic third ventriculostomy and biopsy the tumor with the single burr hole technique, allowing both procedures through the same approach.
