Abstract
Cerebrospinal fluid (CSF) fistulas can become a life-threatening condition. These occur following a penetrating injury of the leptomeninges, dura, and bone, resulting in an extracranial discharge of CSF and providing an entry for pathogens into the subarachnoid space, potentially leading to meningitis. Therefore, early diagnosis of a CSF leak in patients with rhinorrhea or otorrhea of uncertain origin is essential.
