When there is doubt about the origin of the blood, the diagnosis of a basilar skull fracture must be excluded. [15]. Disruption of the barriers between the sinonasal cavity and the anterior and middle cranial fossae is the underlying factor leading to the discharge of CSF into the nasal cavity. Meningoencephaloceles usually present in childhood as an intranasal/extranasal mass that transilluminates and expands with crying (Furstenberg sign). Generally, the goal of imaging is confirmation of the diagnosis of SIH through the visualization of a leak, as well aslocalization of the leak, to facilitate targeted treatment with either epidural patching or surgery. CSF and blood disseminate at different rates due to different fluid densities creating a double ring with blood surrounded by a ring of CSF. Delayed fistulas are difficult to diagnose and can occur years after the trauma or operation. Federal government websites often end in .gov or .mil.

Circulation of CSF is maintained by the hydrostatic differences between its rate of production and its rate of absorption. Conclusion: Ideally, the contrast medium is concentrated in the intracranial anterior and posterior skull base regions under fluoroscopic guidance by tilting the prone patient head downward on a fluoroscopic tilt table. Iatrogenic causes include neurosurgical and otolaryngologic approaches to neoplastic disease, as well as functional endoscopic sinus surgery (FESS). Oh JW, Kim SH, Whang K.

This sign appears when CSF mixes with blood on an absorbent surface, such as paper or bed sheets, and creates a double ring pattern. This terminology seems to imply that spontaneous CSF leaks are idiopathic in nature; however, recent evidence has led us to realize that spontaneous CSF rhinorrhea may in reality be secondary to an intracranial process, namely elevated intracranial pressure (ICP). Compared with external techniques, endoscopic techniques have several advantages, including better field visualization with enhanced illumination and magnified, as well as angled, visualization. Despite relatively low levels of evidence, recommendations for the diagnosis and management of CSF rhinorrhea can be made based on the current literature. Observe with a Wood lamp 30 minutes later for fluorescence of nasal discharge; if present, this confirms CSF . In-111 has minimal background activity and does not accumulate in the brain. This article discusses current concepts in the etiology, diagnosis, and treatment of CSF rhinorrhea, as well as long-term management of patients following successful treatment. Fluid contained in the meningocele and leaked fluid in the sphenoid sinus outline the meningocele membrane.

The patient is maintained in the prone position until a CT scan is performed. In many cases, a CSF leak will heal on its own accord following conservative treatment, including strict bed rest, increased fluid intake and caffeine. Extradural fluid collections are common in spinal CSF leak. Cochrane Database Syst Rev. 2005;38[4]:597), an elegant study from 1993 shows the double ring sign is neither sensitive nor specific for CSF.
