The use of topical intranasal fluorescein in endoscopic endonasal repair of cerebrospinal fluid rhinorrhea. The opposite is true for nontraumatic leaks, as only one third stop spontaneously. All methods of cisternographyradionuclide, CT, and MRprovide improved or optimal CSF fistula detection when the fistula is active and when a Valsalva maneuver or jugular venous compression is added to the imaging protocol. Disclaimer. Otolaryngology procedures, including FESS and septoplasty, can lead to a skull base defect and CSF rhinorrhea. 2022. Skull Fracture Additionally, a mixture of at least 30 percent CSF to blood was required to produce a double ring sign reliably, so the absence of a double ring sign does not exclude a CSF leak.

Drainage may be intermittent as the fluid accumulates in one of the paranasal sinuses and drains externally with changes in head position (ie, reservoir sign). CSF fistula can usually be demonstrated by using some method of cisternography. Contrast medium has drained out of the meningocele, but a small amount remains in the sphenoid sinus around the meningocele. Double ring sign | definition of double ring sign by Medical dictionary Meningoencephaloceles usually present in childhood as an intranasal/extranasal mass that transilluminates and expands with crying (Furstenberg sign). Immediate traumatic leaks result from a bony defect or fracture in conjunction with a dural tear.

CT showed decreased thickening of the arterial wall and was negative for the double-ring sign (Figure 1B). FOIA Beta-2 transferrin is the most reliable confirmatory test for CSF leak. Also, it serves as nutrient delivery and waste removal system for the brain. One drop of blood and one drop of either spinal fluid, saline, tap water, or rhinorrhea fluid were placed simultaneously on filter paper, and the specimens were examined after ten minutes for the development of a ring. Septal bone is used as an underlay graft in the repair of this skull base defect in a patient with a spontaneous leak and encephalocele. Beta-2 transferrin is the most reliable confirmatory test for CSF leak. Each patient subsequently underwent a procedure for an epidural blood patch, and all patients experienced symptomatic relief. 2nd edition. double-ring sign (Figure 1B).

Spontaneous CSF rhinorrhea occurs in patients without antecedent causes. 29 (3):207-10. Extradural fluid collections are common in spinal CSF leak. The underlying defect responsible for cerebrospinal fluid (CSF) leaks, regardless of the etiology, is the same: disruption in the arachnoid and dura mater coupled with an osseous defect and a CSF pressure gradient that is continuously or intermittently greater than the tensile strength of the disrupted tissue. Accessibility Cerebrospinal fluid (CSF) leak may occur from the nose (rhinorrhea), from the external auditory canal (otorrhea), or from a traumatic or operative defect in the skull or spine. CT scans may demonstrate skull base defects resulting from accidental or iatrogenic trauma, an underlying anatomic or developmental abnormality, or an erosive lesion such as a neoplasm. 2011 May. 26(7):628-9. The dura of the anterior cranial base is subject to wide variations in CSF pressure because of several factors, including normal arterial and respiratory fluctuations. Some otolaryngologists use a dilute solution of fluorescein to localize CSF fistulas both preoperatively and during surgery. [4], CT cisternography or radionuclide cisternography may be useful if CT and MR cisternography do not show the CSF fistula. double ring sign: two concentric rings around the optic nerve characteristic of optic nerve hypoplasia.

The intrathecal injection of gadolinium-based contrast media has been shown in several off-label studies to be effective and safe in selected patients in whom other cisternographic or myelographic studies have failed to demonstrate the CSF leak site. A biopsy should never be obtained unless a complete imaging workup has been conducted. Typically, 0.5 mL of a 10% fluorescein solution is injected into the lumbar subarachnoid space over more than 1 minute. Gadolinium-enhanced, T1-weighted axial MRI obtained 2 weeks after a 7-mL extradural blood patch was applied to the midlumbar region.

The 'ring sign': is it a reliable indicator for cerebral spinal fluid?. The fluid can be placed on filter paper and a "halo" or double ring may be seen. The intrathecal injection of 0.5 mL of gadopentetate dimeglumine diluted in 3-5 mL of CSF for MR cisternography has been reported to have high sensitivity and specificity for detection of active CSF fistula, exceeding the rate of fistula demonstration by CT, nuclear medicine, or noncontrasted MR cisternography. After transfer, a bloody discharge was noted from his right external auditory canal, and the right tympanic membrane was perforated. Coronal CT images of 2-3 mm thickness are then obtained through the face and cranium, including all of the paranasal sinuses and the mastoid air cells.
