2015 Feb. 23 (1):59-64. Vanopdenbosch LJ, Dedeken P, Casselman JW, Vlaminck SA. Slow CSF leaks may be detected by postmyelogram CT scan in which there is a time delay between the contrast medium intrathecal injection in the fluoroscopic room and subsequent transfer to the CT scan room. DeConde AS, Suh JD, Ramakrishnan VR. Ryall RG, Peacock MK, Simpson DA. 2022 Nov;36(11):859-864. doi: 10.13201/j.issn.2096-7993.2022.11.010. [QxMD MEDLINE Link]. 1993 Apr. Although the value of this sign has been debated, an experiment showed that the sign was consistently visible when CSF concentrations were 30%90% when mixed with blood.2 However, the sign was not specific to CSF: mixtures of blood with saline, tears or rhinorrhea also produced halos; filter paper, paper towel, coffee filters and linen all showed a ring.2, Guidelines recommend a CT scan of the head when basal skull fracture is suspected.3 Although CSF leakage occurs in 2%21% of basal skull fractures, a recent review does not support the use of prophylactic antibiotics to prevent the development of meningitis.4. CSF consists of a mixture of water, electrolytes (Na+, K+, Mg2+, Ca2+, Cl-, and HCO3-), glucose (60-80% of blood glucose), amino acids, and various proteins (22-38 mg/dL). Conclusion: Nuclear cisternogram obtained at 24 hours demonstrates diffuse epidural accumulation of the tracer in the midlumbar region. (Defect measured approximately 7mm.). One test involves placing a sample of what the doctor suspects to be CSF discharge on a piece of filter paper . Rapid detection of heavy elements in blood extracted from wounds using x-ray fluorescence analysis. 30 (6):424-9. 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. If CSF is present, a dextrose stick test may be positive. Bookshelf A variety of cisternographic studies may be necessary to localize some spinal CSF fistulas. Pledgets are placed close to the cribriform plate, in the middle meatus, and in the sphenoethmoidal recess of the right and left nasal cavities. This test uses the principle of chromatography: different components of a fluid mixture will separate as they travel through a material. All editorial matter in CMAJ represents the opinions of the authors and not necessarily those of the Canadian Medical Association or its subsidiaries. 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). All of these changes are reversible with ablation of the cause of CSF leak, which is usually in the spine. Defects in the closure of the anterior neuropore can result in the herniation of central nervous tissue through anterior cranial fossa. The frequency of cerebrospinal fluid (CSF) rhinorrhea is determined by the underlying etiology. [28], In a small series of patients withspontaneous intracranial hypotension (SIH), instillation of preservative-free normal saline into the thecal sac followed by intrathecal Gd infusion was found to be a safe technique thatincreased the detection of a CSF leak on MR myelography images. ( Cochrane Database Syst Rev. Sagittal magnetic resonance cisternogram demonstrates the connection of the meningocele to the middle cranial fossa; this finding facilitated surgical planning. If persistent fluid drainage occurs after a fracture, the fluid may be evaluated to test for the presence of CSF. 2015 Jan-Feb. 29 (1):77-81. Paraspinal fluid collections can be localized for needle aspiration with ultrasound guidance. CSF will separate from blood when the mixture is placed on filter paper resulting in a central area of blood with an outer ring or halo. To study the development of a ring sign when blood is mixed with various fluids. Fluid contained in the meningocele and leaked fluid in the sphenoid sinus outline the meningocele membrane. For more information, see Medscape. 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 MR cisternography may demonstrate inactive CSF fistulas.

Please confirm that you would like to log out of Medscape. J Neurosurg. Epub 2013 Jul 1. Obstructive sleep apnea (OSA) has also been linked to elevated ICP. Allows to idebtify if bloody fluid from ears/ nose contains CSF. [QxMD MEDLINE Link]. Double ring sign. Optic nerve deficits suggest a lesion in the region of tuberculum sellae, sphenoid sinus, or posterior ethmoid cells. Brain tissue herniation is best seen on MRI. Hence, the surgical team should be prepared to repair the resulting CSF leak at the time of the resection, either transcranially or endoscopically. 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. In radiology, the halo sign is a finding of a dark halo around the arterial lumen on ultrasound that suggests the diagnosis of temporal arteritis. Usefulness of beta 2-transferrin assay in the detection of cerebrospinal fluid leaks following head injury. Intrathecal fluorescein (IF) may also be of benefit in certain clinical scenarios. Drops of fluid from a CSF leak placed on absorbent filter paper may result in the double-ring sign, a central circle of blood and an outer clear ring of CSF. A variety of filter paper agents were used, including standard laboratory filter paper, paper towels, coffee filters, and bed linens. An absorptive sponge pad placed at or near the presumed site of fluid leak can facilitate the collection of the fluid. In patients with head trauma, a mixture of blood and CSF may make the diagnosis difficult. 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. The result will form two distinct rings, called a "target" or "double ring" sign. Lee TJ, Huang CC, Chuang CC, et al. The ring sign: Is it a reliable indicator for cerebral spinal fluid? A control pledget for lacrimal secretions is placed under one inferior nasal turbinate. A paediatric case of bilateral mandibular condyle fracture presenting with bloody otorrhoea following trauma. [16] Contemporary computer-reconstructed coronal images are usually of diagnostic quality, and direct CT coronal images may not be necessary. Free shipping for many products! This patient presented with a spontaneous onset of cerebrospinal fluid rhinorrhea 10 years after a head injury. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. A systematic review of the literature was performed using PubMed, EMBASE, and Cochrane databases from January 1990 through September 2014, to examine 9 diagnostic and localization modalities for CSF rhinorrhea. Blunt trauma is the most common cause. A 58-year-Old non-smoking woman with intractable cough and rhinorrhea. [QxMD MEDLINE Link]. Hegarty SE and Millar JS. Federal government websites often end in .gov or .mil. However, an astute clinician noted the double ring sign on the stretcher sheet, as noted in the Figure 1. Delayed fistulas are difficult to diagnose and can occur years after the trauma or operation. 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. Endoscopic endonasal minimal access approach to the clivus: case series and technical nuances. 2020 Apr 10. Am J Rhinol Allergy. Gadolinium-enhanced T1-weighted axial MRI shows diffuse moderate dural thickening with contrast enhancement. It cushions your brain and spinal cord from injury. The localization of one or multiple leaks can make possible and facilitate therapeutic CT-guided epidural blood patching. Would you like email updates of new search results? [29]. An official website of the United States government. 2015 Apr 28. Distinguishing blood due to a basilar skull fracture from cutaneous bleeding using the "halo sign" (applying a drop of blood to a filter paper looking for more rapidly diffusing cerebrospinal fluid surrounding the blood), is often cited but unreliable (3-5). Immediate traumatic leaks result from a bony defect or fracture in conjunction with a dural tear. Radiol Clin North Am. -2 transferrin is a protein found in CSF, but not in serum, nasal secretions, or adjacent tissue. Ratilal BO, Costa J, Pappamikail L, Sampaio C. Antibiotic prophylaxis for preventing meningitis in patients with basilar skull fractures. When CSF rhinorrhea is suspected, fluorescein may be injected into the lumbar subarachnoid space. Wolters Kluwer Health Axial magnetic resonance cisternogram demonstrates the connection of the meningocele to the middle cranial fossa (arrows).

Contrast medium has drained out of the meningocele, but a small amount remains in the sphenoid sinus around the meningocele. Toxicology Rounds: A Non-Diabetic with Lactic Acidosis? 83(987):225-32. However, locally aggressive lesions such as inverted papilloma and malignant neoplasms can erode the bone of the anterior cranial fossa. 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. Benedict PA, Connors JR, Timen MR, Bhatt N, Lebowitz RA, Pacione DR, Lieberman SM. This sign appears when CSF mixes with blood on an absorbent surface, such as paper or bed sheets, and creates a double ring pattern. Magnetic resonance cisternography (MRC) should be used for CSF leak identification as a second line for each of these if beta-2 transferrin is not available or if HRCT is ambiguous. Once in contact with the paper, any CSF will separate from any. This occurred on bed linen, filter paper, absorbent paper, and coffee filters. G-CSF-induced vasculitis has been reported to occur in 0.47% of patients. [QxMD MEDLINE Link]. Diagnosis of cerebrospinal fluid rhinorrhea: an evidence-based review with recommendations.

The resulting communication with the central nervous system (CNS) can result in a multitude of infectious complications that impart significant morbidity and potentially disastrous long-term deficits for the patient. Teachey W, Grayson J, Cho DY, Riley KO, Woodworth BA. Skull base injuries can vary from simple cracks in the bony architecture to large (>1 cm) defects with disruption of the dura and potentially brain parenchyma. 2008 Mar-Apr. Careers. Dynamic CT myelography is recommended in these patients, with the injection of the iodinated contrast medium intrathecal on the CT scan table with immediate spine CT scan. 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. Careers. CSF produced at the choroid plexus typically circulates from the lateral ventricles to the third ventricle via the aqueduct of Sylvius.
