Endoscopic Transnasal Transclival Approach to a Pontine Cavernoma with Associated Developmental Venous Anomaly

This approach provided direct visualization of the lesion and the associated DVA allowing for a gross total resection without injury to the DVA. The transclival approach may be considered as an alternative to open lateral and dorsolateral neurosurgical approaches for ventral brainstem cavernomas in carefully selected patients.
