Endoscopic Transpterygoid Corridor for Petroclival Tumors: Case Series and Technical Nuances.

Background: The petroclival area is a technically challenging region to operate owing to the proximity of the internal carotid artery (ICA) and the need to obtain gross total excision of tumors in this area as they are often resistant to radiotherapy.

Objective: We present our experience with the endonasal endoscopic transpterygoid approach in managing tumors of the petroclival region and discuss various operative nuances for safer resection.

Materials And Methods: A retrospective study of all consecutive cases of lesions occupying the petroclival region that were operated via endonasal endoscopic transpterygoid approach at our center between January 2016 and December 2021 was performed.

Revisiting Dandy-Walker Malformation with Associated Neurofibromatosis.

This report describes a very rare Dandy-Walker malformation (DWM) associated with neurofibromatosis (NF) and bony defect over torcula emphasizing the role of meticulous follow-up for asymptomatic DWM. The clinical aspects of an adolescent patient with undiagnosed DWM who was asymptomatic until the age of 14 years are being discussed. Computed tomography and magnetic resonance imaging were revealed DWM.

Cyanosis and Clipping: Noninfectious Aneurysm in a Patient with 22q11.2 Deletion Syndrome.

Noninfectious cerebral aneurysms are rare in patients with congenital cyanotic heart disease. We present a patient with DiGeorge/velocardiofacial syndrome with a complex congenital cyanotic heart disease with a ruptured anterior communicating artery aneurysm. The 10-year-old child was managed by surgical clipping of the aneurysm.
