Cerebrospinal fluid (CSF) leak: Symptoms, treatment, and more If persistent fluid drainage occurs after a fracture, the fluid may be evaluated to test for the presence of CSF. If CSF is present, a dextrose stick test may be positive. Each patient subsequently underwent a procedure for an epidural blood patch, and all patients experienced symptomatic relief.

Lanny Garth Close, MD Chair, Professor, Department of Otolaryngology-Head and Neck Surgery, Columbia University College of Physicians and Surgeons The incidence of CSF fistula detection varies from 22 to 100% in clinical studies. This site needs JavaScript to work properly. Paradoxical rhinorrhea occurs when midline structures that act as separating barriers (eg, crista galli, vomer) are dislocated. Magnetic resonance cisternogram with cerebrospinal fluid rhinorrhea demonstrates a meningocele extending into the left lateral recess of the sphenoid sinus (arrows). HHS Vulnerability Disclosure, Help [1] The fluid leak is a result of meningeal dural and arachnoid laceration with fistula formation. 19(4):627-31. El Gammal T, Sobol W, Wadlington VR, et al. Additional hardware or software is not required to perform MR myelography or cisternography. 22(2):151-4. In most cases of iatrogenic injury presenting in a delayed fashion, surgical repair is necessary. Diagnosis of cerebrospinal fluid rhinorrhea: an evidence-based review with recommendations. Marshall AH, Jones NS, Robertson IJ. The brain is noted to sink downward in the cranium with development of a pseudo-Chiari I malformation. A defect in the skull base is measured with a sterile ruler. CSF fistula can usually be demonstrated by using some method of cisternography. Laryngoscope. J Neurol Neurosurg Psychiatry.
