title: Isolated pyocele of anterior clinoid process presenting as a cavernous sinus syndrome.
abstract: A 37-year-old man presented with fever, decreased vision in the left eye, a partial left cranial nerve III paresis, and a left cranial nerve VI paresis. Neuro-imaging showed an opacification of a left pneumatised anterior clinoid process. After failing a course of intravenous antibiotics, a craniotomy was performed with exenteration of the cavity and resolution of symptoms. Although rare, a pyocele of a pneumatised anterior clinoid process may cause ocular morbidity and require surgical intervention.
