Spontaneous cerebrospinal (CSF) rhinorrhea is a well-known entity, representing approximately 5% of all CSF leaks. These leaks usually originate from the lamina lateralis, lamina cribrosa, fovea ethmoidalis, and lateral sphenoid recess. We discuss a highly unusual case of spontaneous CSF rhinorrhea emanating from a foramen cecum defect in the posterior frontal sinus table; describe the presentation, imaging findings, and surgical repair; and provide a possible explanation for its origin. A review of the literature revealed no previous similar case.
