Abstract

Treating meningeal tumours invading the large dural venous sinuses is a subject of debate regarding the approach for removing the intra-sinus components. Additionally, directly observing the invasion site of tumours invading the lateral wall of the sinus is difficult. We describe our exo- and endoscopic two-step approach (EETA): an exoscope is used to remove the extra-sinus component, while an endoscope is used to observe the invaded lateral wall and remove the intra-sinus component. EETA can be a viable option for treating meningeal tumours invading the venous sinus owing to its high resection rate and low invasiveness.
