Symptomatic intracranial arachnoid cysts are commonly treated using neuroendoscopy.
Cysts located within the posterior fossa may present a greater surgical challenge
to the neurosurgeon due to the numerous vital neurovascular structures located within
this confined space. Adding neuronavigation during endoscopy helps a neurosurgeon
to visualize and utilize both anterior and posterior corridors safely to access and
manage these lesions. We present three symptomatic posterior fossa arachnoid cysts
that were treated successfully using minimally invasive neuronavigation-guided endoscopic
neurosurgery utilizing the anterior transfrontal transaqueductal, anterior transfrontal
transtrigonal, and posterior suboccipital infratentorial supracerebellar approaches.
