This is the case of a 25-year-old woman who had had a previous rupture of a dermoid cyst and now presented with recent MRI scans suggesting further growth of her dermoid cyst. Her lesion was located in the suprasellar space and extended into the interpeduncular fossa and prepontine cistern. Considering the location of the tumor, an endoscopic pituitary hemitransposition was selected for its resection. In this video we present the technical nuances and illustrate the anatomy used for an endoscopic endonasal pituitary hemitransposition for resection of a suprasellar dermoid cyst with extension into the interpeduncular fossa. In this case, a near-total resection was achieved, with no complications and no additional hormonal deficit after surgery.
