Occipital Transtentorial Resection of a Mature Teratoma in The Pineal Region
Abstract
A 22-year-old presented with a large pineal region tumour. He presented to a peripheral hospital with obstructive hydrocephalus and an endoscopic third ventriculostomy was performed with a concomitant biopsy that was non-diagnostic. We took the patient to the operating room for definitive resection of this tumour through an occipital transtentorial approach. Intraoperatively, there were clearly two different morphologies to the tumour, which suggested a mixed cell type tumour. The final pathology was a mature teratoma.
