Endoscopic approaches to the posterior wall of the third ventricle: An anatomical comparison.

Introduction: Surgery of lesions in the posterior wall of the third ventricle requires great expertise due to its deep location and important surrounding structures. This region has been traditionally reached through a supracerebellar infratentorial approach, but new options have emerged, especially with the development of neuroendoscopy.

Methods: One formalin-fixed cadaver human head was dissected.

Cardiac amyloidosis in patients with spinal stenosis and yellow ligament hypertrophy.

Background: Spinal stenosis (SS) is a manifestation associated with cardiac amyloidosis (CA). However, there is a lack of studies assessing the prevalence of CA among patients with SS. We aimed to address the prevalence of CA among patients with SS and YLH.

Accessory nerve ancient schwannoma: A case report.

Background: Lower cranial nerve schwannomas are rare and only 63 cases originating from the accessory nerve have been documented.

Case Description: We report a 61-year-old man who presented with a 3-month history of dysmetria, ataxic gait, and frequent falls. Magnetic resonance imaging revealed a giant rim-enhancing cystic lesion at the right cerebellomedullary cistern, which markedly displaced the brainstem and caused a critical compression on surrounding structures and mild hydrocephalus.

Pulmonary arterial hypertension due to ventriculoatrial shunts: A case report and literature review.

Cardiopulmonary complications are infrequent in patients with ventriculoatrial shunts (VAS). We report the case of an 18-year-old man with congenital hydrocephalus who developed pulmonary arterial hypertension (PAH) in the long-term follow-up after a VAS procedure. He presented with progressive exertional dyspnea, stabbing chest pain and acral cyanosis.
