Pseudomeningoceles of the sphenoid sinus masquerading as sinus pathology.

ABSTRACT:

Objectives/hypothesis

To describe the clinical presentation, pathophysiology, and treatment of spontaneous cerebrospinal fluid (CSF) leaks of the sphenoid bone, with an emphasis on a previously undescribed form in this location, in which CSF is trapped under the mucosa of the sinonasal cavity or in the soft tissue of the skull base.

Study design

Case series and literature review.

Methods

Analysis of cases through medical records and literature review.
