Cerebrospinal fluid leak

Cerebrospinal fluid (CSF) is a colorless, transparent fluid found in the ventricles and subarachnoid space. The production, absorption, and flow of CSF play a crucial role in the dynamics of intracranial pressure. When the CSF cavity communicates with the outside, leading to CSF leakage, it is called cerebrospinal fluid rhinorrhea or otorrhea. CSF leakage can alter CSF pressure, leading to a series of neurological symptoms, most commonly headache. It is more common in adults. The incidence in children is significantly lower than in adults due to their softer and more elastic skulls and incompletely developed paranasal sinuses.

Skull base tumors

Skull base tumors refer to tumors that originate and grow in the skull base and surrounding tissues, including tumors of the brainstem, the superior surface of the skull base bone, the skull base bone itself, and the inferior surface of the skull base bone. These tumors can extend cranially, invading the intracranial cavity, or caudally, affecting areas such as the orbit, paranasal sinuses, nasal cavity, infratemporal fossa, and parapharyngeal space. They encompass a wide variety of tumor types, many of which are rare. Due to the diverse nature and extensive scope of skull base tumors, they can be observed in all age groups. Relatively, the incidence of discovery is higher in adulthood.
