Transclival pseudomeningocele secondary to ecchordosis physaliphora: case report and literature review.

ABSTRACT

We describe a 52-year-old woman who presented with meningitis secondary to a pseudomeningocele within the sphenoid sinus derived from a bony defect in the clivus. The bony defect was radiologically characteristic of an ecchordosis physaliphora (EP). She underwent surgical repair of the defect and had resolution of her symptoms. This case report will discuss the second case of transclival pseudomeningocele in the English literature and present EP as a cause.
