Lanny Garth Close, MD Chair, Professor, Department of Otolaryngology-Head and Neck Surgery, Columbia University College of Physicians and Surgeons 33(3):535-40. [QxMD MEDLINE Link]. Delayed fistulas are difficult to diagnose and can occur years after the trauma or operation. DeConde AS, Suh JD, Ramakrishnan VR. A positive diagnosis of CSF fistula is made by finding direct continuity of the CSF fistula with the subarachnoid space. government site. A control pledget for lacrimal secretions is placed under one inferior nasal turbinate. Epub 2013 Jul 1. Pledgets are scanned in a glass tube at intervals of 2-24 hours, with the highest count rate indicating a possible leak site. Results: [31] Cotton pledgets labeled for the placement site are positioned in the nose before the lumbar subarachnoid space injection of the isotope. The doublering sign found in contrastenhanced computed tomography, which reflects inflammatory changes in the adventitia and oedema of the intima, is thought to be characteristic of. Toxicology Rounds: A Non-Diabetic with Lactic Acidosis? Serum glucose, chloride,. 2010 Mar. These symptoms also occur in multiple common conditions and so should be evaluated by an ENT specialist if they are not easily explained or do not clear up on their own in a week or so. Some otolaryngologists use a dilute solution of fluorescein to localize CSF fistulas both preoperatively and during surgery.

High-Resolution Computed Tomography as an Initial Diagnostic and Localization Tool in Patients with Cerebrospinal Fluid Rhinorrhea: A Meta-Analysis. [1] The fluid leak is a result of meningeal dural and arachnoid laceration with fistula formation. A 27-year-old male driver in a single-vehicle rollover collision was transferred to a trauma centre after stabilization and endotracheal intubation at a community hospital. Any surgical manipulation near the skull base can result in an iatrogenic CSF leak. 2022 Dec 8;12(12):1685. doi: 10.3390/brainsci12121685. [QxMD MEDLINE Link]. The growth of benign tumors does not commonly result in CSF rhinorrhea. Please try after some time. Circulation of CSF is maintained by the hydrostatic differences between its rate of production and its rate of absorption. [24] Most MRI machines offer fat suppression and image gray-scale reversal. The most rudimentary test is for a so-called double ring sign (Fig. Oakley GM, Alt JA, Schlosser RJ, Harvey RJ, Orlandi RR. [30] The sensitivity for CSF leaks is in the range of 50-100%. 2007 Dec. 28(8):1131-9. The result will form two distinct rings, called a "target" or "double ring" sign. Another technique, the injection of intrathecal fluorescein, has been used not only to diagnose CSF rhinorrhea but to localize the site(s) where it occurs. The management of CSF rhinorrhea depends on the cause, location, and severity of the leak. What's the Most Likely Cause of This Man's Severe Headaches? The accuracy of active fistula detection with CT cisternography is 65-85%. Despite relatively low levels of evidence, recommendations for the diagnosis and management of CSF rhinorrhea can be made based on the current literature. Conclusion: (See images below.). J Neurotrauma. [15]. Wolters Kluwer Health, Inc. and/or its subsidiaries. The frequency of cerebrospinal fluid (CSF) rhinorrhea is determined by the underlying etiology. A new approach for simple radioisotope cisternography examination in cerebrospinal fluid leakage detection. Neurosurgery. Double Ring Sign (on bedding, paper) CSF Leakage will form appearance of watermelon in cross section Large Inner ring of pink, bloody CSF fluid Small outer ring of clear CSF fluid (analogous to the rind of a watermelon) Bedside Glucose of draining fluid CSF fluid will have bedside Glucose >30 mg/dl IV. This test uses the principle of chromatography: different components of a fluid mixture will separate as they travel through a material. A short repetition time can be used to achieve a result similar to that of the technique above, with slightly faster imaging times. In patients with nonsurgical trauma, waiting a period of 5-7 days to allow conservative measures (bed rest, stool softeners, and lumbar drainage) to assist with secondary closure of the traumatic defect is reasonable. However, locally aggressive lesions such as inverted papilloma and malignant neoplasms can erode the bone of the anterior cranial fossa. [QxMD MEDLINE Link]. Evaluation of high-resolution CT and MR cisternography in the diagnosis of cerebrospinal fluid fistula. Treatment of cerebrospinal fluid rhinorrhea. Positive predictive values of selected clinical signs associated with skull base fractures. The most common fracture sites leading to CSF leaks are the frontal sinus (30.8%), sphenoid sinus (11.430.8%), ethmoid (15.419.1%), cribriform plate (7.7%), frontoethmoid (7.7%), and sphenoethmoid (7.7%). J Neurosurg. 2016 Jan;6(1):8-16. doi: 10.1002/alr.21637. This dislocation allows CSF to flow to the opposite side and manifest at the contralateral naris. Magnetic resonance myelogram demonstrates pseudomeningoceles secondary to a stretch injury of the lumbosacral nerve roots. Gadolinium-enhanced, coronal, T1-weighted MRI. There may be apparent downward displacement of the optic chiasm.

The enzymatic breakdown or destruction of the bony architecture results in inflammation and potential violation of the dura. Cerebrospinal fluid (CSF) rhinorrhea is a rare but potentially devastating condition that can lead to significant morbidity and mortality for the patient. Paradoxical rhinorrhea occurs when midline structures that act as separating barriers (eg, crista galli, vomer) are dislocated. The high T2 signal from CSF fistula may be difficult to differentiate from that of sinusitis on axial images. Localization of the leak to the right or left nasal cavity may be difficult because of the tendency of the fluid to cross sides and flow from both nostrils.

Usefulness of beta 2-transferrin assay in the detection of cerebrospinal fluid leaks following head injury. 2008 Jan. 29(1):116-21. This image represents an endoscopic view with a 70-degree telescope through the left frontal recess. These are infrequently associated with CSF rhinorrhea. 93(6):E14-9. The lateral lamella of the cribriform plate appears to be involved in approximately 40% of the cases, whereas a defect in the region of the fontal sinus is detected 15% of the time. The ring is a result of the different densities of blood and CSF, and is concerning for a basilar skull fracture., While the presence of a double ring sign (sometimes called a halo sign) is often cited as indicating the presence of CSF (Sapira's Art and Science of Bedside Diagnosis. Bernard D Coombs, MB, ChB, PhD Consulting Staff, Department of Specialist Rehabilitation Services, Hutt Valley District Health Board, New ZealandDisclosure: Nothing to disclose. Surgical outcomes of the endonasal endoscopic approach within a standardized management protocol for repair of spontaneous cerebrospinal fluid rhinorrhea. We are prepared to diagnose any electrical problem you're facing and resolve it. Federal government websites often end in .gov or .mil. Mjovsk M, Grotenhuis A, Foroglou N, Zenga F, Froehlich S, Ringel F, Sampron N, Thomas N, Komarc M, Netuka D. Neurosurg Rev. The leak almost never recurs. 8600 Rockville Pike 2017 Feb. 78 (1):18-23. CT findings associated with cerebrospinal fluid leaks include fractures or other bone defects; meningocele; focal fluid accumulation in the ethmoid air cells; frontal, sphenoid, or maxillary sinuses or mastoid air cells; and, sometimes, pneumocephalus. This finding is consistent with a meningoencephalocele of the temporal bone. Reddy M, Baugnon K. Imaging of Cerebrospinal Fluid Rhinorrhea and Otorrhea. [QxMD MEDLINE Link]. For example, anosmia (present in 60% of individuals with post-traumatic rhinorrhea), indicates an injury in the olfactory area and anterior fossa, especially when it is unilateral. Compared with external techniques, endoscopic techniques have several advantages, including better field visualization with enhanced illumination and magnified, as well as angled, visualization. Sagittal magnetic resonance cisternogram demonstrates the connection of the meningocele to the middle cranial fossa; this finding facilitated surgical planning. Brain tissue herniation is best seen on MRI. Temporal lobe gyral herniation may occur through a petrous temporal bone tegmen tympani defect. 2001 Aug. 22(7):1239-50. By the same principles as those applied in planar chromatography, the drainage of bloody discharge onto the patient's pillow or a paper towel can be seen to . Another advantage is the ability to more accurately position underlay or overlay grafts. Cerebrospinal fluid fistula: detection with MR cisternography. 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. It should be kept in mind, however, that this test does not provide information regarding the site or laterality of the defect. Triplanar images of a patient with a left lateral recess meningoencephalocele. [19]. [QxMD MEDLINE Link]. Hoshino H, Higuchi T, Achmad A, Taketomi-Takahashi A, Fujimaki H, Tsushima Y. G-CSF-induced vasculitis has been reported to occur in 0.47% of patients. Double Ring Sign: CSF mixed with blood or nasal discharge forms two rings because CSF being a watery fluid invades linen more than blood called the double-ring sign, halo sign, or . Sign in 0 Cart; Gifts for Mom; Jewelry & Accessories . Spinal radiological findings in nine patients with spontaneous intracranial hypotension. This feature is the basis for a specific test for CSF based on immunoelectrophoresis. [16] Contemporary computer-reconstructed coronal images are usually of diagnostic quality, and direct CT coronal images may not be necessary. Spinal MRI in patients with SIHS may show some irregularity of the thecal sac due to partial dural collapse. Clinical images are chosen because they are particularly intriguing, classic or dramatic. 19(4):627-31. AJNR Am J Neuroradiol. Lee TJ, Huang CC, Chuang CC, et al. 92(5):873-6. In-111 has minimal background activity and does not accumulate in the brain. Please enable it to take advantage of the complete set of features! For otorrhea, 1 cotton pledget is placed in each external auditory canal. 2015 Sep. 123 (3):732-6. 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. A defect in the skull base is measured with a sterile ruler. 2016 Nov. 6 (11):1126-30. [QxMD MEDLINE Link]. The investigators suggested that intracranial hypertension may put patients at risk for developing these defects. 1993 Apr. 2011 Apr. By the same principles as those applied in planar chromatography, the drainage of bloody discharge onto the patient's pillow or a paper towel can be seen to . After transfer, a bloody discharge was noted from his right external auditory canal, and the right tympanic membrane was perforated. Int Forum Allergy Rhinol. Am J Rhinol Allergy. 29 (3):207-10. Albayram S, Kilic F, Ozer H, Baghaki S, Kocer N, Islak C. Gadolinium-enhanced MR cisternography to evaluate dural leaks in intracranial hypotension syndrome. Coronal CT image of the temporal bone demonstrates a bone defect (small arrows) in the tegmen tympani with a protruding soft-tissue meningoencephalocele (large arrows). sharing sensitive information, make sure youre on a federal CSF and blood disseminate at different rates due to different fluid densities creating a double ring with blood surrounded by a ring of CSF. [9]. [QxMD MEDLINE Link]. Surg Neurol. Extradural fluid collections are common in spinal CSF leak. Gadolinium-enhanced T1-weighted axial MRI shows diffuse moderate dural thickening with contrast enhancement. For more information, see the eMedicine topic Nephrogenic Systemic Fibrosis. 2015 Apr 28.

A variety of filter paper agents were used, including standard laboratory filter paper, paper towels, coffee filters, and bed linens. Cerebrospinal fluid imaging. 1-7. A lumbar drain placed at the time of repair has not been shown to decrease recurrence of the CSF leak. The patient's severe postural headaches were markedly decreased in intensity. In contrast to traumatic leaks, only 50% of patients with iatrogenic CSF leaks present within the first week after the insult. Please confirm that you would like to log out of Medscape. Digital subtraction radiographic cisternography can be similarly performed with a spinal subarachnoid injection of nonionic iodinated contrast medium. [22, 25] Gadolinium-based contrast media are approved for intravenous injection for MRI but have not been approved for intrathecal use in humans by the Food and Drug Administration (FDA). Skull radiographs are of limited diagnostic use in CSF leaks, but they may show a relevant skull fracture or the presence of empty sella. Methods: A variety of filter paper agents were used, including standard laboratory filter paper, paper towels, coffee filters, and bed linens. Zuckerman JD, DelGaudio JM. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. With one method, the average total time for coronal and sagittal imaging is 48 minutes. ), She stated that the cerebrospinal fluid (CSF) double ring sign raises concern about a CSF leak. CTA, MRA, or digital subtraction cerebral and cervical arteriography may then be necessary.

The fluid can be placed on filter paper and a "halo" or double ring may be seen. National Library of Medicine Several texts have suggested that CSF will separate from blood when the mixture is placed on filter paper or other media and will produce a clinically detectable sign, which has been referred to as a ring sign, double ring sign, or halo sign. Bethesda, MD 20894, Web Policies 134:110044. Case report. Iatrogenic causes include neurosurgical and otolaryngologic approaches to neoplastic disease, as well as functional endoscopic sinus surgery (FESS). Head images are acquired 2, 6, 12, and 24 hours after injection of the isotope. [QxMD MEDLINE Link]. B2Tr may be found in blood serum in liver disease, such as in chronic alcoholism and in patients with inborn errors of glycoprotein metabolism or genetic variants of transferrin. 28.10). -2 transferrin is a protein found in CSF, but not in serum, nasal secretions, or adjacent tissue. 2020;42[12]:31; http://bit.ly/2HVJcdt. Laryngoscope. 19(4):633-9. 2014 Jul;15(4):363. doi: 10.5811/westjem.2014.4.21346. The CSF double ring sign is based on the principle that blood and CSF will disseminate at different rates, due to different uid densities, creating a ''double ring,'' one of blood, 2nd edition. Conservative treatment has been advocated in cases of immediate-onset CSF rhinorrhea following accidental trauma, given the high likelihood of spontaneous resolution of the leak. To study the development of a ring sign when blood is mixed with various fluids. ISSN 1488-2329 (e) 0820-3946 (p). Cappabianca P, Cavallo LM, Esposito F, et al. 2012 Mar. [QxMD MEDLINE Link].

Intracranial repair was frequently used (and is still used in select cases) for the routine repair of anterior cranial fossa CSF leaks. Traumatic cerebrospinal fluid leak. The most rudimentary test is for a so-called double ring sign (Fig. A large defect is noted, and the meningocele has been resected. Cerebrospinal fluid (CSF) leaks are generally classified as traumatic, iatrogenic, and spontaneous/idiopathic. [QxMD MEDLINE Link]. CT cranial cisternography is performed with injection of 5-7 mL of nonionic myelographic contrast medium into the lumbar subarachnoid space. Various other authors, including Dohlman (1948), Hirsch (1952), and Hallberg (1964), subsequently reported successful repair of CSF rhinorrhea through different external approaches. J Neurol Surg B Skull Base. Bookshelf Intrathecal fluorescein (IF) may also be of benefit in certain clinical scenarios. Diagnosis of cerebrospinal fluid rhinorrhea: an evidence-based review with recommendations. In the study, about 72% of patients with spontaneous CSF leaks were female, and about 45% had obstructive sleep apnea. Double Ring Sign (on bedding, paper) CSF Leakage will form appearance of watermelon in cross section Large Inner ring of pink, bloody CSF fluid Small outer ring of clear CSF fluid (analogous to the rind of a watermelon) Bedside Glucose of draining fluid CSF fluid will have bedside Glucose >30 mg/dl 5 Testing fluid from the ear or nose for -2 transferrin is the recommended method to assess patients for a cranial CSF leak because this approach is noninvasive as well as highly sensitive and specific.
