CSF rhinorrhea associated with the empty-sella syndrome
Summary
Empty-sella syndrome involves cerebrospinal fluid (CSF) extending into the sella turcica, potentially causing CSF rhinorrhea. Early diagnosis and a multidisciplinary approach are crucial for effective management.
Area of Science:
- Neurosurgery
- Endocrinology
- Radiology
Background:
- Empty-sella syndrome is characterized by an abnormal extension of an arachnoid diverticulum into the sella turcica.
- This condition can compress the pituitary gland and erode the sellar floor.
Observation:
- The erosion can lead to cerebrospinal fluid (CSF) rhinorrhea through the sphenoidal sinus.
- Nontraumatic CSF rhinorrhea warrants consideration of empty-sella syndrome.
Findings:
- Definitive diagnosis requires advanced imaging like pneumoencephalography and thin-section polytomography.
- Coexisting pituitary adenomas should be investigated.
Implications:
- A multidisciplinary team approach involving otolaryngology, neurosurgery, neuroradiology, and neuroendocrinology is optimal for diagnosis and treatment.
- Transsphenoidal surgery can effectively repair CSF leaks associated with this syndrome.
