Endoscopic endonasal pituitary hemitransposition for resection of suprasellar and retrosellar dermoid cyst.

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. The video can be found here: https://youtu.be/BHtNf5invUI.

Endoscopic Removal of Suprasellar Colloid Cyst with Interpeduncular and Prepontine Cisterns Extension.

Colloid cysts (CCs) are rarely found in the sellar-suprasellar region. Differential diagnosis of CCs is more challenging in this region because many other cystic lesions may locate or invade sellar or suprasellar structures. We present a large and unusual case of sellar-suprasellar CC with extension into the suprasellar, interpeduncular, and prepontine cisterns. This is the first case of sellar-suprasellar CC treated with an endoscopic transsphenoidal approach. A 33-year-old woman presented with a 1-year history of recurrent headaches. Her headaches had been unresponsive to medical treatment for the last 2 weeks. She had normal neurologic and ophthalmologic examinations. Neuroradiologic studies showed a large cystic sellar lesion with extension into the suprasellar, interpeduncular, and prepontine cisterns. The lesion did not show any enhancement, not even in the cyst wall. Her hormonal status was also normal. The cystic lesion was totally resected via a purely endoscopic endonasal approach. There were no complications, and the patient was recovered completely with improvement of her headache. Pathology was consistent with a CC. At 6-month follow-up, magnetic resonance imaging did not show any evidence of the residual or recurrent lesion. Although rarely found in this location, CC should be considered in the differential diagnosis in patients who present with a sellar-suprasellar cystic lesion. Additionally, sellar-suprasellar CC would be a good candidate for the endoscopic endonasal approach.
