Granular cell tumors of the sellar region: what should be done after subtotal resection? A systematic review.

Purpose: Granular cell tumors (GCT) are highly vascularized and adherent to adjacent structures, and so, complete resection represents a challenge. Adjuvant therapy decisions for residual GCTs currently relies on individual clinician decisions due to a paucity of systematic literature data. We present a comprehensive analysis about the impact of adjuvant therapy in reported cases of patients with incomplete GCT resection.

[Purely endoscopic supracerebellar infratentorial approach for epidermoid cyst in third ventricle].

Background: The epidermoid cyst as a pineal region tumor is an infrequent pathology and with few descriptions in literature. Its prevalence in the third ventricle is 0,0042% of all intracranial tumors. To achieve a complete exéresis we used an endoscopic supracerebellar-infratentorial approach, surgical technique for pineal region approach.

Clivus Hemangioma in a Pediatric Patient: Case Report.
