Background: Cerebrospinal fluid (CSF) leak is a devastating complication after transsphenoidal surgical approach to pituitary adenoma and sellar repair has been postulated as crucial step in this approach. In this study, we describe our experience regarding sellar repair in pure endoscopic endonasal approach in 240 patients with pituitary adenoma. Methods: During April 2005 to April 2011, a tot...

Intracranial hypotension is a rare cause of persistent headache mostly originating from a dural CSF leak. If a conservative treatment fails, a minimally invasive EBP can lead to a successful sealing of such a leak. Independent of the leakage site, an EBP is usually applied at the lumbar level with varying success. We used CT myelography to detect the site of the dural leakage, then immediately ...

Dural tears can occur during spinal surgery and may lead to cerebrospinal fluid (CSF) leakage which is rarely involved in remote cerebellar hemorrhage. Only a few of cases of simultaneous cerebral and cerebellar hemorrhage have been reported in the English literature. We experienced a case of multiple remote cerebral and cerebellar hemorrhages in a 63-year-old man who exhibited no significant n...

A 45-year-old female patient visited the hospital complaining of severe sudden headache and posterior neck pain. The patient did not have any traumatic history or abnormal neurologic finding. The patient had sudden quadriplegia and sensory loss. Cervical spine MRI scan was taken, and the compatible findings to acute epidural hematoma were shown. The emergency operation was performed. After the ...

Rhinorrhoea is a clinical sign of cerebrospinal fluid (CSF) leakage in patients with skull fracture, but can also be attributable to respiratory secretions or tears. Laboratory tests confirming the presence of CSF are not sufficiently rapid to support clinical decision making in the emergency department and may not be universally available. Detection of glucose in nasal discharge was traditiona...

Subfrontal schwannomas are rarely reported. They are usually found only in the subfrontal area, but some extend to the nasal cavity. In these cases, prevention of postoperative cerebrospinal fluid (CSF) leakage through thinned or eroded anterior skull base is important. A 51-year-old female with anosmia and mild nausea was diagnosed as subfrontal extraaxial mass with nasal cavity extension. Thi...
