Spontaneous Cerebrospinal Fluid Rhinorrhea: A Case Report.

Cerebrospinal fluid (CSF) rhinorrhea refers to the loss of CSF through the nasal cavity. Its causes can be classified as either spontaneous or non-spontaneous. Spontaneous causes of CSF rhinorrhea include congenital anatomical defects and are extremely rare, accounting for less than 4% of reported cases. Following failure of conservative management, definitive treatment most commonly involves an endoscopic transsphenoidal repair of the defect. We present a case of spontaneous CSF rhinorrhea in a previously well 52-year-old female, which required surgical intervention due to failure of conservative management.
