Blood alone does not produce a ring. Other stresses include Valsalva-like maneuvers during nose blowing or straining. Fast spin-echo T2-weighted coronal image of a patient with a spontaneous onset of cerebrospinal fluid rhinorrhea demonstrates an empty-sella configuration. 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. MRI with intrathecal gadolinium to detect a CSF leak: a prospective open-label cohort study. Zuckerman JD, DelGaudio JM. 2020;42[12]:31; http://bit.ly/2HVJcdt. The image also shows a right-sided meningocele (large arrow) protruding through the cribriform plate, which was not suspected but was surgically repaired at the same time as the left cribriform cerebrospinal fluid leak site. The leak almost never recurs. According to another theory, the tear and bony defect are present from the time of the original injury, but the leak occurs only after the masking hematoma dissolves.

Gosal JS, Gurmey T, Kursa GK, Salunke P, Gupta SK. 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. Therefore, it is important to keep in mind exactly what you said while also making sure a CSF leak and a basilar skull fracture are not missed. 2015 Feb. 23 (1):59-64.

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. G-CSF-induced vasculitis has been reported to occur in 0.47% of patients. 142:43-7. Rapid echo-planar imaging with the patient in the prone position and performing a Valsalva maneuver may allow for limited coronal imaging and increase the accuracy of MR cisternography. 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.

Even if the tumor itself does not lead to CSF rhinorrhea, the resection typically results in immediate leakage. However, locally aggressive lesions such as inverted papilloma and malignant neoplasms can erode the bone of the anterior cranial fossa. The brain is noted to sink downward in the cranium with development of a pseudo-Chiari I malformation. Rapid detection of heavy elements in blood extracted from wounds using x-ray fluorescence analysis. One test involves placing a sample of what the doctor suspects to be CSF discharge on a piece of filter paper . CSF leak; CSF rhinorrhea; cerebrospinal fluid; diagnosis; diagnostic algorithm; localization. The type of filter paper did not affect the development of a ring. Enrique Palacios, MD, FACR Professor of Radiology, Tulane University Medical Center [QxMD MEDLINE Link]. Occasionally, a stream of contrast medium is demonstrated at the fistula site. The images may demonstrate a CSF fistula, but this technique is used less frequently than other cisternographic methods. NSF/NFD has occurred in patients with moderate to end-stage renal disease who have been given a gadolinium-based contrast agent to enhance MRI or MRA scans. CSF is colorless, clear, and typically devoid of cells such as polymorphonuclear cells and mononuclear cells (< 5/L). All rights reserved.

Neuroimaging features of spontaneous intracranial hypotension. Another Na+/K+ ATPase lining the ventricular side of the epithelium extrudes Na+ into the ventricle, with water following across this ionic gradient. This sign appears when CSF mixes with blood on an absorbent surface, such as paper or bed sheets, and creates a double ring pattern. 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.

However, an astute clinician noted the double ring sign on the stretcher sheet, as noted in the Figure 1. A halo pattern on a bedsheet produced by bloody otorrhea from a 27-year-old man who had been in a motor vehicle collision. Intervention for elevated intracranial pressure improves success rate after repair of spontaneous cerebrospinal fluid leaks. We do not capture any email address. 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 . It is produced in epithelial cells of the choroid plexus and meninges and is found in CSF, perilymph, seminal fluid, and urine. Wolters Kluwer Health 34(7):410-6. [QxMD MEDLINE Link]. Beta2-transferrin assay is currently single best laboratory test for identifying the presence of CSF in sinonasal fluid. doi: 10.1371/journal.pntd.0004516. This study may also be useful for detecting inactive fistulas, intermittent leaks, or suspected meningoencephaloceles. Epub 2013 Jul 1. Spontaneous CSF rhinorrhea: prevalence of multiple simultaneous skull base defects. Typically, the leak is caused by either spontaneous dural dehiscence or dural tears caused by degenerative causes. From the first intracranial repair in the 1900s to the use of endoscopes and image-guidance systems, the management of cerebrospinal fluid (CSF) rhinorrhea has greatly evolved. 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. 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%). High-resolution CT (HRCT) is then recommended as the first-line study for localization. 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. MRI in the Localization of CSF Fistulae: Is It of Any Value?. Diagnosis of cerebrospinal fluid rhinorrhea: an evidence-based review with recommendations. 1994. CSF leaks will often resolve within seven days with very few complications, and no clear evidence supports antibiotic prophylaxis for these leaks in the first seven days. European Pituitary Adenoma Surgery Survey (EU-PASS) results-technical part. In most cases of iatrogenic injury presenting in a delayed fashion, surgical repair is necessary. If CSF is present, a dextrose stick test may be positive. Gadolinium-enhanced T1-weighted axial MRI shows diffuse moderate dural thickening with contrast enhancement. A suggested algorithm for the diagnosis of a CSF fistula follows. 2015 Jan-Feb. 29 (1):77-81. Paradoxical rhinorrhea occurs when midline structures that act as separating barriers (eg, crista galli, vomer) are dislocated. Neurosurgery. Bharucha T, Chanthongthip A, Phuangpanom S, Phonemixay O, Sengvilaipaseuth O, Vongsouvath M, Lee S, Newton PN, Dubot-Prs A. PLoS Negl Trop Dis. The embryologic defect is typically a patent fonticulus frontalis or foramen cecum. Reddy M, Baugnon K. Imaging of Cerebrospinal Fluid Rhinorrhea and Otorrhea. 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). Sagittal magnetic resonance cisternogram demonstrates the connection of the meningocele to the middle cranial fossa; this finding facilitated surgical planning. The dye reaches the skull base in 6 hours and is present over the cerebral convexities in 24 hours. 2016 Jan. 206 (1):8-19. Epub 2012 Aug 13. [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. 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. CSF is produced at a rate of approximately 20 mL/h for a total of approximately 500 mL daily. After intrathecal fluorescein is administered, an exposed frontal recess encephalocele is seen. Breaking News: A Catastrophic Match: Now What? Lobo BC, Baumanis MM, Nelson RF. [QxMD MEDLINE Link]. 2015 Sep 15. Serum glucose, chloride,. On occasion, the patient has a history of headache relieved by drainage of CSF. 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. Endoscopic management of spontaneous CSF rhinorrhea with septal graft and middle turbinate rotational flap technique: a review of 31 cases. 52:768-770. With one method, the average total time for coronal and sagittal imaging is 48 minutes. Baltimore: Lippincott, Williams & Wilkins; 2003. 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. 2010 Mar. [QxMD MEDLINE Link]. 2016 Nov. 6 (11):1126-30. L Gill Naul, MD Professor and Head, Department of Radiology, Texas A&M University College of Medicine; Chair, Department of Radiology, Baylor Scott and White Healthcare, Central Division 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. CSF is manufactured continuously in areas of the brain called ventricles, and the bloodstream absorbs it. Cisternography with an intrathecal injection of radioisotope or nonionic iodinated myelographic contrast medium or MRI cisternography usually localizes the CSF leak. 2002 Feb. 44(2):143-50; discussion 151-2. Intermittent leakage over several years is characteristic. A high rate of fistula detection may be possible with imaging in the prone position, but this may be uncomfortable for the patient. Dandy is credited with the first surgical repair of a CSF leak via a frontal craniotomy approach in 1926. Case report. Normal CSF pressure is approximately 10-15 mm Hg, and elevated pressure constitutes an intracranial pressure (ICP) greater than 20 mm Hg. 2014 Sep. 59 (2):196-9. Neuroradiology. J Neurotrauma. Dr. Kaplan responds: Thank you so much for your thoughtful reply to my article. Skull radiographs are of limited diagnostic use in CSF leaks, but they may show a relevant skull fracture or the presence of empty sella. Compared with external techniques, endoscopic techniques have several advantages, including better field visualization with enhanced illumination and magnified, as well as angled, visualization. 2022 Feb;45(1):831-841. doi: 10.1007/s10143-021-01614-1. A history of headache and visual disturbances suggests increased intracranial pressure. [QxMD MEDLINE Link]. (Ann Emerg Med. 4:CD004884. Alternatively, radioactivity of the nasal pledgets is compared with that of known plasma radioactivity. G-CSF-induced vasculitis has been reported to occur in 0.47% of patients.1 The double-ring sign, which reflects inflammatory changes in the adventitia and oedema of the intima, is thought to be characteristic of Takayasu arteritis (TA); however, herein, it was also observed for G-CSF-induced vasculitis.2 It is
