Abstract
The evolution of sphenoid sinus meningoencephalocoeles and cerebrospinal fluid (CSF) rhinorrhoea is poorly understood. We present a case demonstrating the gradual evolution of encephalocoeles from both the lateral walls of a previously normal sphenoid sinus in a patient with dural arteriovenous fistula (DAVF), the CSF leak which developed following staged embolisation of the DAVF was managed by an endoscopic endonasal transpterygoid approach. Our findings suggest that over a period of time, chronic elevation of intracranial pressure (ICP) results in gradual erosion of the lateral wall of the sphenoid with development of meningoencephalocoeles and CSF leaks.
