The video describes the surgical management of a giant pineal tumor resistant to chemotherapy in an 11-month old infant. The child was diagnosed with pineal tumor and hydrocephalus at the age of 7 months in a foreign institution: ventriculoperitoneal shunt was implanted and microsurgical biopsy was performed through a transcallosal approach. Histology was in favour of immature teratoma. Three cycles of chemotherapy were administered but the tumor continued to grow and the patient was referred to our hospital for surgical treatment.
Due to its dimensions (8x5x6 cm), the tumor could not be removed in a single surgical procedure; a staged resection, involving the four surgical procedures described in the video, was therefore planned: 1) Posterior interhemispheric transtentorial approach, very challenging in infants because of the haemorrhagic risks in presence of giant tumors. The techniques and pitfalls of dealing with severe continuous blood loss throughout the internal decompression of the tumor are shown and discussed. 2-3) The re-opening of an anterior interhemispheric transcallosal approach, very challenging as well especially in infants. Dissection and removal of the intraventricular component of the tumor are shown and commented. 4) The removal of the very last tumor nodule, hidden in the postero-superior aspect of the ventricle, through a purely endoscopic approach. The endoscopic procedure, the extensive use of the endoscopic ultrasonic aspirator are very well shown in the video.
Histology was in favor of a rare tumor of the pineal retinal anlage (WHO grade IV). The patient was referred to the neuro-oncology department for pursuit of chemotherapy.

In this video, we present the staged removal of a giant pineal tumor in an infant. I’m am Giuseppe Cinalli, head of the pediatric neurosurgery at Santobono-Pausilipon Children’s Hospital in Naples, Italy.
The clinical case is a seven-month-old baby boy with a pineal tumor and hydrocephalus. Emergency VP shunt and one month later, transcallosal approach for biopsy were performed in another county. And the histological diagnosis was a teratoma. Three cycles of chemo in the country of origin, and an MRI showed tumor progression. So he was referred at the age of 11 months for tumor removal.
