A 46-year-old woman presented with an intermittent nontraumatic cerebrospinal fluid (CSF) left rhinorrhea. A multidetector computed tomographic (MDCT) study was performed to investigate a CSF fistula (Figure). The sphenoidal sinus is prone to CSF leakage, when anatomical variations occur. The basilar expansion is a posterior expansion of the sphenoidal sinus (postsellar). It is considered criti...

Hydrocephalus is defined as an abnormal enlargement of the ventricles of the brain due to an excessive accumulation of cerebrospinal fluid (CSF) because of a disturbance of its flow, absorption and/or secretion. The usual method of CSF diversion is a ventriculo-peritoneal shunt. Complications of implanted shunt systems include mechanical failure, shunt pathway obstruction, infection, foreign bo...

OBJECTIVE The surgical removal of a jugular foramen (JF) tumor presents the neurosurgeon with a complex management problem that requires an understanding of the natural history, diagnosis, surgical approaches, and postoperative complications. Cerebrospinal fluid (CSF) leakage is one of the most common complications of this surgery. Different surgical approaches and management concepts to avoid ...

Spontaneous intracranial hypotension (SIH) is an increasingly recognized syndrome associated with a specific set of clinical and imaging findings; however, determining the site of spinal cerebrospinal fluid (CSF) leakage in these patients is often difficult, and indications for surgical intervention need to be better defined. The authors report on a 55-year-old woman who presented with posture-...

Association of deep white matter infarction with chronic communicating hydrocephalus: implications regarding the possible origin of normal pressure hydrocephalus. Idiopathic normal pressure hydroceph-alus may be a " two hit " disease: benign external hydrocephalus in infancy followed by deep white matter ischemia in late adulthood. T he article in this month's American Journal of Neuroradi-olog...

Farm workers are at increased risk for animal-inflicted head injuries that are associated with significant morbidity and occasionally may be fatal. These injuries may cause permanent eye damage with or without concomitant skull base fracture. Here, we present a male farmer who suffered a cow attack that resulted in perforating orbital injury with comminuted frontobasal cranial fracture caused b...

Owing to the complexity of spinal surgery, there is a great prevalence of dural tear causing cerebrospinal fluid (CSF) leakage. Many studies focused on suture repair for dural tear to stop CSF leak. Now some new treatment strategies have shown a promising effect that is listed as follows: 1) creating watertight dural closure to stop CSF leak with the help of dural substitute material; and 2) re...

OBJECT The extended transsphenoidal approach is a less invasive method for removing purely suprasellar lesions compared with traditional transcranial approaches. Most advocates have used a sublabial incision and a microscope and have reported a significant risk of cerebrospinal fluid (CSF) leakage. The authors report on a series of purely endoscopic endonasal surgeries for resection of suprasel...

We propose a double layered (intradural and epidural patch) duraplasty that utilizes Lyoplant and Duraseal. We examined a 47-year-old woman after decompression for thoracic ossification of posterior longitudinal ligament was performed in another hospital. On postoperative day 7, she complained of weakness in both legs. Postoperative magnetic resonance imaging (MRI) showed cerebrospinal fluid (C...

We aimed to compare systemic and cerebral hemodynamics coughing during emergence after pituitary surgery endotracheal tube (ETT) extubation or replacing ETT with a laryngeal mask airway (LMA). Patients were randomized awaken an in place it LMA. recorded mean arterial pressure (MAP), heart rate, middle artery (MCA) flow velocity, regional oxygen saturation (SrO2), cardiac index, plasma norepinep...
