This case highlights the interplay of skull base defects and intracranial pressure in cerebrospinal fluid rhinorrhea, suggesting improved diagnosis and management.
This case highlights the interplay between skull base defects and ICP, including subclinical IIH, in spontaneous CSF rhinorrhea. Surgical repair unmasked symptomatic IIH and dynamic venous sinus stenosis secondary to elevated ICP. Recognizing this pathophysiology enables accurate diagnosis, avoids unnecessary intervention, and guides appropriate management. https://thejns.org/doi/10.3171/CASE25775.
